If this is it for Jaso, the 34-year-old will be hanging up the spikes after 2591 career PA over parts of nine seasons with the Rays, Mariners, A’s and (for the last two seasons) Pirates.  Injuries and struggles against left-handed pitching limited Jaso’s usage as an everyday player, though he was very productive in various part-time capacities.  Jaso posted good career splits against right-handed pitching and was an above-average run producer overall in six of his eight full seasons, finishing with a 115 wRC+ for his career.  If this it for Jaso, we wish him congratulations on a fine career and we tip our hats to his most immediate postseason endeavor — helping with relief efforts in Puerto Rico.

Here’s the latest from both the NL and AL Central…

• The Tigers have asked the Rays about third base coach Charlie Montoyo, FanRag Sports’ Jon Heyman reports (Twitter links).  It’s hard to know where Montoyo sits on the Tigers’ list of managerial candidates due to the sheer number of names in their search; according to Heyman, Detroit began the process with around 50 names under consideration.  Montoyo, who has also drawn interest from the Mets, has been Tampa’s third base coach for three seasons and a manager at all rungs of their minor league system from 1997-2014.
• Matt Carpenter won’t require surgery on his right shoulder, he tells MLB.com’s Jenifer Langosch (Twitter link).  An MRI revealed only inflammation in the shoulder, which has been a nagging concern for the Cardinals infielder.  Possibly due to the injury, Carpenter saw drops in his batting average and slugging percentage from his previous two seasons, though he was still quite productive, hitting .241/.384/.451 with 23 home runs over 622 plate appearances for St. Louis.
• The rebuilding process for the White Sox has gone according to plan thus far, though as CSN Chicago’s Dan Hayes writes, the team has another long year ahead of it next season.  “We know we might be entering a slightly more difficult phase of this rebuild, and that is the phase where we have to allow this talent the time and patience to develop….We’re going to have to remain diligent and realize that this isn’t about any individual player or any individual season, this is about building something for the long term,” GM Rick Hahn said.  “For this next phase, that’s going to require player development to play its important role and for us to have patience in Chicago that would allow that to unfold.”
• Earlier today on MLBTR, we checked in with more notes from both Central divisions, including items on the Royals, Indians, Cardinals and Tigers.

More from Rosenthal:

• The Astros appeared to be making a serious push for Athletics righty Sonny Gray at one point this week, but they’re not aggressively involved in the sweepstakes for the 27-year-old right now, according to Rosenthal (FanRag’s Jon Heyman issued a similar report Thursday). Given the recent success of starters Mike Fiers and Brad Peacock, Houston could pursue an elite reliever instead of another piece for its rotation, suggests Rosenthal, who adds that prospect Derek Fisher will likely take over in left field next month if the team doesn’t trade him. Baseball America’s 54th-ranked prospect, the 23-year-old has slashed .311/.380/.584 with 21 home runs and 16 steals across 375 Triple-A plate appearances this season. Fisher got his first taste of big league action last month and swatted two homers in just 21 trips to the plate.
• As one would expect, the Rangers will have an “awfully high” asking price for ace Yu Darvish if they do market him, relays Rosenthal. Even though Darvish is an impending free agent on a team that doesn’t look likely to make the playoffs, trading him isn’t as obvious as it might seem, contends Rosenthal. Not only do the Rangers “have an unusually close relationship” with the 30-year-old and a desire to keep him for the long haul, but retaining Darvish for the stretch run will give them a better chance to make up a 4.5-game deficit in the wild-card race. Also, they’d lose the ability to make Darvish a qualifying offer after after the season, which Rosenthal regards as a formality. The Rangers will net a pick after the second round if they issue Darvish a QO and he rejects it.
• If the Braves trade lefty Jaime Garcia, they might use the money they save by dealing him (up to $4.7MM) to acquire a controllable reliever, says Rosenthal, who lists the Orioles’ Brad Brach as a possibility. Brach may not be a realistic target, though, given that Orioles general manager Dan Duquette shot down the idea of trading veterans Saturday.

• The Pirates have shifted Andrew McCutchen back to center field will utilize a combination of Adam Frazier, Josh Harrison, John Jaso and Jose Osuna (who was called up from Triple-A following Marte’s suspension) in right field, as MLB.com’s Adam Berry writes in an excellent breakdown on the fallout from Marte’s 80-game ban. The Bucs have no plans to shift Josh Bell back to the outfield at this time, per Berry.
• While the immediate reaction from many was that Marte’s suspension could open a window for touted outfield prospect Austin Meadows, GM Neal Huntington ruled out that possibility (also via Berry’s piece). “We’re encouraged by where Meadows will be at some point over the course of the summer,” Huntington told reporters. “He’s not ready right now, but we’re thrilled by where he can go.” It’s hard to refute Huntington’s assessment; even though Meadows clearly comes with a lofty ceiling, he’s followed up last year’s .214/.297/.460 showing in 175 Triple-A plate appearances with a mere .146/.217/.244 line through 46 PAs in Indianapolis this season. The Pirates typically wait until their top prospects have avoided Super Two status before promoting them to the Majors anyhow, but statistically speaking, Meadows has yet to demonstrate that he’s ready for more advanced competition.
• Marte first tested positive early in Spring Training, reports USA Today’s Bob Nightengale, but he was allowed to play through this point in the season as his appeal process played out. Nightengale adds that while the Pirates could theoretically make a run at Angel Pagan now with a hole in the outfield, they’ll likely pass. Huntington suggested that trades aren’t an option at this time, Nightengale adds. In Berry’s column above, Huntington indeed suggested that trades for impact players at this point of the season are “not real,” and he cast some doubt on bringing in a free agent: “We’ll always look for ways to improve the club. It would have to be someone who is a significant upgrade over our internal options.”
• Marte’s teammates, certainly, are disappointed by the news, but they also offered messages of support following the news, writes Stephen J. Nesbitt of the Pittsburgh Post-Gazette. McCutchen, Josh Harrison, Gregory Polanco and Gerrit Cole were among the members of the Pirates roster quoted in Nesbitt’s column. “He’s not exiled,” Harrison told reporters. “He made a mistake.” Polanco and Cole both referred to Marte as their “brother” when speaking to the media. “When you make a mistake, you gotta pay for it,” McCutchen said to reporters before also voicing his support. “…I’m just trying to be a good friend before I am a teammate.”
• Cubs first baseman Anthony Rizzo was among the players to call for more testing throughout the league. Rizzo was doing an interview with Yahoo’s Big League Stew at the time the news of the suspension hit, and told them (Twitter link): “It kinda makes you angry as a player, because you know there are still flaws in the system, you know there are still guys getting away with it. For me, I’ve been drug tested zero times this year. Not once since the beginning-of-Spring-Training standard drug test. Guys are going to get away with it as long as they can and obviously everybody’s going to say they didn’t know they were doing it.” Many current and former players took to social media to call for more stringent testing policies and, in some cases, harsher punishment for first-time offenders.
• ESPN’s Buster Olney opines that Marte’s suspension taints his legacy in Pittsburgh to the point that he can never provide a suitable return on their long-term investment in him. Marte’s suspension comes early in a pivotal season for the Pirates that may very well be McCutchen’s last year in black and yellow, Olney notes, and Pittsburgh had very little margin for error as it sought to keep up with the Cubs and Cardinals. While it’s hard to disagree with the notion that Marte’s suspension is a poorly timed blow that that Pirates could ill afford, the suggestion that he’s “torpedoed” his value beyond repair seems excessive. Marte is earning a combined $17.5MM in 2018-19 and has a pair of reasonably priced club options for the 2020 and 2021 seasons.
• Yahoo’s Jeff Passan lists a number of myths and truths about performance enhancing drugs in a reaction column, ultimately calling for transparency and regulated use of certain substances (though not necessarily Nandrolone). Passan points out that some steroids are already commonly used (e.g. cortisone injections for pain) as a reference point when citing that the term “performance enhancing drugs” is rather arbitrary in its nature. “There is a place for chemistry in baseball and all other sports, and it is in a tightly regulated, ever-evolving partnership with doctors, chemists, politicians, ethicists, management and players to develop fair rules for sport while acknowledging sport itself can benefit from the use of drugs,” writes Passan. “The rules in place now don’t work. They never have. They never will.” Passan also suggests that PEDs will never be eradicated from baseball and disagrees with any suggestion that Marte’s value has somehow been erased by the suspension, among other points.
• Marte might be the best player (at the time of his punishment) to ever receive a suspension for performance enhancing drug use, writes The Ringer’s Ben Lindbergh. Lindbergh profiles the numerous reasons that Marte has flown under the radar as one of Major League Baseball’s most underrated and unheralded stars in recent years, though certainly now that view will be tainted in the eyes of many. As Lindberg adds, there’s a cascading effect of Marte’s suspension, in that the downturn in the Pirates’ expected performance will now make a trade of McCutchen and, eventually, a promotion of Meadows all the more likely.

• With Mark Teixeira retiring, the Yankees will have a new regular first baseman next season for the first time since Teixeira’s arrival in 2009, Chad Jennings of Lohud.com writes. GM Brian Cashman says the Yankees’ default approach next season will be to go with younger options at first. “[W]ithout having advance notice on what becomes available and what gets presented to you in various concepts – I would that that would be the way that we like to approach this going into Spring Training of next year,” he says. “Let the kids get a shot at it.” Greg Bird, Tyler Austin and Rob Refsnyder could all get opportunities at the position. Bird is currently playing in the Arizona Fall League after having missed the 2016 season due to a shoulder injury. If he proves he’s healthy, one would think he would have the inside track on playing time after batting .261/.343/.529 in his first 178 big-league plate appearances in 2016.
• Top Cubs executive Theo Epstein sees parallels between the organization he currently runs and the one he led while with the Red Sox, Evan Drellich of the Boston Herald writes. Epstein’s Cubs made their first playoff run last season but were ousted by the Mets in the NLCS. His first playoff team in Boston fell in the ALCS to the other New York franchise in 2003. The next year, of course, the Red Sox won their first World Series since 1918. “I’ve had some flashbacks here and there. First few days of the offseason last year, after getting knocked out by the Mets, definitely felt like the same kind of galvanizing time that we had in Boston after Aaron Boone walked us off,” Epstein says. “Hopefully the same results: ’03 to ’04, ’15 to ’16.”
• News that the Nevada Assembly has approved expenditures for a stadium designed to lure the Raiders from Oakland has no immediate impact on the Athletics, writes John Hickey of the Bay Area News Group. A’s owner Lew Wolff says he hasn’t heard anything about the possibility that the Raiders’ option to tell the A’s to find a new place to play should the Raiders find a home somewhere besides the Oakland Coliseum. “They were going to have to have a firm financial plan in place here if they were going to give us notice, and it doesn’t seem like that’s happening,” says Wolff. The A’s have been exploring other stadium options in Oakland, but for now, they don’t have any concrete plans to move.

A bit more from the NL Central…

• Reds manager Bryan Price tells MLB.com’s Mark Sheldon that Jose Peraza could remain with the team for the rest of the year even if Zack Cozart returns quickly from a minor Achilles injury, but he stopped short of committing to the notion of Peraza sticking in the Majors through the end of the Triple-A season on Sept. 5. As Sheldon notes, Peraza was scarcely used when he spent a month and a half in the Majors earlier this summer, but he’s had a pair of multi-hit games since being recalled to fill in for Cozart at shortstop and could get looks at second base, in left field and in center field over the course of September in an effort to see what he can do with consistent playing time against MLB pitching. It would be somewhat strange for the Reds not to work him into the lineup as much as possible in order to get a better evaluation of Peraza, especially considering the fact that he can be deployed at a number of positions.
• Having watched Dansby Swanson, Alex Bregman and Andrew Benintendi go from the 2015 draft to the Majors less than a year later, Reds third base prospect Nick Senzel said on the MLBPipeline.com podcast that he hopes for a similarly quick ascent (also via Sheldon). Senzel, the No. 2 overall pick in this season’s draft, is hitting .309/.400/.545 with seven homers in 46 games with Class-A Dayton. He hasn’t been moved quite as aggressively as Bregman, who played at Class-A Advanced during his debut season, but neither Swanson nor Benintendi topped Class-A last season and both still made it to the bigs this year. “You look at those guys … get there their first full year, as a player and a college hitter that makes you hungry to get up there,” said Senzel.
• Brewers left-hander Chris Capuano isn’t likely to return to the team in 2016, GM David Stearns tells Tom Haudricourt of the Milwaukee Journal-Sentinel. The 38-year-old has been sidelined by an elbow injury since late May, and a platelet-rich plasma treatment hasn’t sped along his recovery as much as had been hoped. Stearns notes that Capuano “is still very motivated to make it back and continue his career,” so it sounds as if there’s a good chance he’ll aim to return in 2017 if he can’t do so at the tail end of the present season.
• Another Brewers southpaw, Sean Nolin, recently underwent Tommy John surgery after trying to stave off the procedure, Haudricourt further reports. He, too, tried a PRP treatment but did not improve enough to avoid a UCL replacement. Milwaukee outfielder Rymer Liriano, meanwhile, has faced slow going after being struck by a pitch in the face this spring. Though he has now begun baseball activities, Liriano won’t be able to make it to the majors this year. Instead, says Stearns, he may be able to participate in fall instructional league action.

• In an interview with Jim Duquette and Jim Bowden on MLB Network Radio on Sirius XM (audio link), Brewers GM David Stearns discussed that his team’s plan “at this stage [is to] acquire and develop the best young talent we possibly can,” and thus if teams come calling about Milwaukee’s young players, Stearns would want an “exceptionally high” return.  Stearns, however, didn’t exactly say that this makes a veteran player like Jonathan Lucroy or Ryan Braun more likely to dealt.  In fact, he noted that the possibility of trading Braun hasn’t been something that he’s had to seriously consider in his brief time as Milwaukee’s GM, and “there is no motivation for us to move…an elite-level player.”  That said, Stearns did say he’d already talked to both Braun and Lucroy about the trade rumors circling around both men and said he’d keep them appraised of any developments should they arise.  Stearns expects “active discussions” leading up to the trade deadline he said the Brewers “are in a situation where we need to be open-minded and we need to be open to any possibility.”
• If the Cubs keep running away with the NL Central, ESPN’s Buster Olney (subscription required) feels the Pirates may focus on deadline acquisitions that can help them in 2017, as reaching the coin flip that is the Wild Card game isn’t worth giving up substantial talent for a short-term rental.
• While the Pirates may have a need at catcher, both Clint Hurdle and Neal Huntington felt John Jaso’s past concussion history ruled him out of consideration for work behind the plate, Bill Brink of the Pittsburgh Post-Gazette tweets.  Chris Stewart and the newly-acquired Erik Kratz look to handle the catching duties while Francisco Cervelli is on the disabled list.
• It doesn’t appear that Sean Burnett will exercise his June 15 opt-out clause even he isn’t on the Twins’ Major League roster, Mike Berardino of the St. Paul Pioneer Press reports (via Twitter).  Burnett signed a minor league contract with Minnesota in May, his fourth minors deal with as many clubs since November following prior agreements with the Braves, Dodgers and Nationals.  The veteran southpaw has a 2.66 ERA over 20 1/3 relief innings at Triple-A this season as he looks to return to the bigs for the first time since undergoing Tommy John surgery in 2014.
• Bryan Shaw had another tough outing on Saturday, leading Paul Hoynes of the Cleveland Plain Dealer to wonder if the Indians need to look for a more reliable setup man at the deadline.  Shaw’s season has been a roller-coaster, going from a terrible April to lights-out in May and thus far shaky in June, all adding up to a 5.18 ERA, 9.25 K/9 and 3.33 BB/9 over 24 1/3 innings.  Shaw’s main problem has been the long ball, as his whopping 2.2 HR/9 is more than triple his career average prior to this season.

Here’s more out of Pittsburgh:

• Juan Nicasio’s ability to command the fastball will determine if he can have an impact as a starting pitcher, writes Sawchik. The veteran righty has pitched well this spring with 16 strikeouts, three walks, and no runs allowed in 10 innings. Nicasio is now a viable alternative to Jon Niese, Jeff Locke, or Ryan Vogelsong. However, he might be better suited for relief work since his velocity played up to 96 mph out of the Dodgers bullpen last season. He’s sat 92 to 95 mph this spring as a starter.
• While pitching coach Ray Searage gets the credit for the Pirates ample success with starting pitchers, it’s an organization-wide philosophy, writes Rob Biertempfel of the Pittburgh Tribune-Review. Jim Benedict, now with the Marlins, helped to develop the philosophy. Now it falls to others in the organization like Double-A pitching coach Justin Meccage to continue implementing their proven techniques. While baseball strategy is important, Searage cites communication and trust as the keys to the Pirates Way.
• The Pirates have changed their policy for pre-arbitration players after the brouhaha with Gerrit Cole, GM Neal Huntington said on MLB Network Radio. Huntington admits the policy was probably outdated before the incident with Cole. Previously, the club followed strict policies for setting pre-arbitration salaries. Teams do this to minimize the need for negotiations over relatively small amounts of money. A set policy can also help to avoid hurt feelings or disputes. Obviously, that wasn’t the case here.

• There’s a case to be made that Royals GM Dayton Moore qualifies as MLB’s most notable figure in 2015, ESPN.com’s Jerry Crasnick writes. While the publication gave that title to Bryce Harper, but the successful culmination of Moore’s efforts in Kansas City certain made for a notable story — particularly from a hot stove perspective.
• New Pirates first baseman John Jaso said yesterday on MLB Network Radio on Sirius XM (Twitter link) that he chose his new team in part due to the opportunity to play in the field. Most of the interest he saw was from American League clubs that would have utilized him as a DH, but he says he’s drawn by the challenge of being a quality defender at a new position.
• While the White Sox have had “dialogue” with the top three free agent outfielders — that’d be Justin Upton, Yoenis Cespedes, and Alex Gordon — there’s nothing close at present, Bob Nightengale of USA Today recently tweeted. That’s not particularly surprising to hear, in part because Chicago seems to be set up rather nicely to be an opportunistic buyer rather than focusing on getting a particular player at all costs.

• This offseason has been notable for the large contracts pitchers like Zack Greinke and David Price have received. Meanwhile, wages for relievers have remained flat, MacPherson writes. Greinke and Price’s deals are now the highest and second-highest ever in average annual value among contracts for pitchers, while the largest deal for relievers this offseason has been Darren O’Day’s four-year, $31MM deal. Admittedly, this offseason’s market hasn’t been heavy on top-flight closers, and new contracts for Ryan Madson (three years, $22MM) and Tony Sipp (three years, $18MM) do perhaps suggest some wage growth for talented middle relievers. Overall, though, as MacPherson points out, the market for elite relievers does not appear to have grown much in the many years since Jonathan Papelbon, Francisco Cordero and B.J. Ryan signed long-term contracts in the $46MM-$50MM range.
• The Pirates took a slight gamble with their signing of C/DH John Jaso, in that they signed him to play first base, Jeff Sullivan of FanGraphs writes. The Pirates themselves have seen the downside of gambling that a player can make an easy transition to first base — Pedro Alvarez’s defense there in 2015 was disastrous. As Sullivan points out, though, catchers from Buster Posey to Carlos Santana to Joe Mauer to Jason Phillips have generally done well in transitioning to first base. (I’d add Pickin’ Machine Scott Hatteberg to the mix as well.) Offensively, Sullivan writes, Jaso needs to be platooned, but he can be very effective against righties.

• The Pirates have outrighted right-hander Jorge Rondon to Triple-A Indianapolis. While Rondon hadn’t been previously designated for assignment, the Buccos needed to clear a roster spot to make way for John Jaso and his new two-year contract, and Rondon was the 40-man casualty. Rondon carried a 2.23 ERA over 60 2/3 innings at Triple-A last year, with 7.4 K/9 against 2.8 BB/9. He was once rated among the top thirty prospects of the Cardinals, and has a track record of solid, if unspectacular, numbers in the minors.
• The Mets have outrighted catcher Johnny Monell to Triple-A Las Vegas, according to ESPN New York’s Adam Rubin (Twitter link). Monell was designated for assignment last week when the team needed a roster spot for the recently re-signed Bartolo Colon. Monell, 30 next March, received his second taste of Major League action last season, collecting a career-high 52 plate appearances with New York. Prior to that, his lone experience in the big leagues was a brief eight-game stint with the 2013 Giants (nine plate appearances). In the Majors, Monell is a .161/230/.196 hitter across his small sample of 61 PAs, but he has a sound track record in the minors, where he’s put together a .279/.356/.455 batting line with 31 homers across 1012 PAs in Triple-A.
• Right-hander Brandon Cunniff has been outrighted to Triple-A Gwinnett by the Braves after clearing waivers, according to a tweet from the team. A former 27th-round draft pick by the Marlins, Cunniff spent three seasons in the independent Frontier League following his brief minor league career with the Marlins. The Braves plucked him from the indy circuit in June of 2013, and he rather quickly rose through their ranks over the past two years. Cunniff posted a brilliant 2.02 ERA in Double-A and jumped directly to the Majors, where he posted a 4.63 ERA with a 37-to-22 K/BB ratio in 35 innings.
• MLB.com’s Greg Johns tweets that outfielder Daniel Robertson has cleared waivers and been outrighted to Triple-A by the Mariners after being designated for assignment last week. Robertson lost his roster spot to the re-signed Hisashi Iwakuma but is clearly a player valued by GM Jerry Dipoto, who acquired him from Texas while serving as GM of the Angels and again picked him up from the Halos this winter after taking over the Mariners’ GM job. In 277 career plate appearances, Robertson is a .274/.324/.325 hitter. He also boasts a solid minor league track record and is capable of playing all three outfield positions, making him a valuable depth option for a big league team.

3:54pm: The Pirates announced that they have signed catcher/first baseman/outfielder John Jaso to a two-year contract. The ACES client will serve as the club’s left-handed half of a first-base platoon, pairing with Mike Morse and/or Jason Rogers to handle those duties.

“John Jaso is a proven Major League hitter who is a great complement to our existing lineup,” said GM Neal Huntington in the club’s press release. “John is enthusiastic about playing in Pittsburgh and developing as a first baseman. We feel he has the ability to play the position at the major league level, while adding significantly to our offensive production.”

Jaso is inexperienced at first base, to be sure, having logged just five innings there at the Major League level and a mere 15 more in the minor leagues. He’ll be learning on the fly, but he won’t have to develop into a plus defender at first base to serve as an upgrade over Pedro Alvarez’s defense. Last season, Alvarez rated 14 runs below average according to both Ultimate Zone Rating and Defensive Runs Saved, despite the fact that he logged just 906 innings at the position. Alvarez was charged with 23 errors in those 906 innings — the third-most of any player at any position in baseball. So, while Jaso will probably experience some growing pains as he learns the intricacies of a new position, the bar for improved defensive production, from the team’s standpoint, is a relatively low one to clear.

Clearly, Jaso wasn’t signed for his glove; he’ll bring to the Pirates a highly productive and exceptionally patient platoon bat to plug into their lineup. The 32-year-old batted .286/.380/.459 in 216 plate appearances in what was an injury-shortened 2015 campaign, with nearly all of his plate appearances coming against right-handed pitching. The Rays permitted Jaso to face a left-handed pitcher just 19 times in 2015, and he’s faced same-handed pitching just 75 times across the past three seasons combined. A platoon partner is a must for Jaso, who is just a .178/.309/.232 hitter against lefties. On the flip side, he boasts an excellent .274/.368/.429 batting line against righties and has been even better in recent seasons, slashing .285/.383/.458 against righties dating back to 2012.

That trait is particularly appealing to the Pirates because, as Travis Sawchik of the Pittsburgh Tribune-Review points out (Twitter link), the Pirates led the Majors in plate appearances against right-handed pitching last season. While some of that is happenstance, looking around the projected rotations of their division rivals, the only lefties that figure to be in Opening Day rotations are Jon Lester, Jaime Garcia and possibly John Lamb/Brandon Finnegan in Cincinnati.

In addition to working at first base, Jaso could also see some time in the corner outfield, tweets MLB.com’s Adam Berry. Jaso has also told the club he’s willing to serve as their emergency catcher, per Berry, though first base and the outfield will be his two primary positions. That’s probably best for Jaso, who has been plagued by concussion issues in recent years, thus necessitating the move to outfield and designated hitter in recent seasons.

Boxberger will likely be the team’s most sought after trade chip and will have the highest price in a trade, Topkin writes, though he notes that McGee is become pricey, at least by the Rays’ standards. Jepsen though, is the likeliest trade candidate among Rays relievers, according to Topkin, as his salary will get a notable bump this winter, and he’s eligible for free agency following the 2016 season. Cotillo also lists Jepsen among the team’s likeliest pieces to move. (He notes, as well, that starters Erasmo Ramirez, Nate Karns and Alex Colome are drawing interest, but the Rays aren’t inclined to deal from their rotation.)

For the Rays to part with Boxberger, one would have to imagine a fairly sizable haul. The 27-year-old came to the Rays along with Logan Forsythe in the trade that sent Jesse Hahn and Alex Torres to the Padres, and he’s been dominant since his acquisition. (He was quite good in San Diego as well.) Boxberger cemented himself as the Rays’ top setup man in 2014, and when McGee required offseason elbow surgery, Boxberger separated himself from the pack to lock down the closer’s role early in the season as McGee recovered. Over the past two years, he’s notched an excellent 2.67 ERA with 13.2 K/9, 3.4 BB/9 and a ground-ball rate a bit north of 40 percent.

In addition to Boxberger’s excellent results, he’s also controllable through the 2019 season, so any team picking him up would be doing so for another four and a half seasons. The former No. 43 overall pick won’t even be eligible for arbitration until after the 2016 season, so it’s easy to see why the Rays would place the highest price tag on Boxberger, whose salary should remain near the league minimum in 2016 and at least manageable for the Rays in 2017.

McGee, on the other hand, is already earning $3.55MM and has been nothing short of dominant since returning from the disabled list. Boxberger has remained the closer for most of the season, which will serve to limit McGee’s forthcoming arbitration raise to some extent, but the hard-throwing lefty still has plenty of holds and strikeouts this season that will come into play in such talks. In fact, McGee has allowed just four runs (three earned) all season long, and each of those runs came in one lone disastrous outing. He’s rattled off 20 consecutive scoreless appearances — a span of 19 1/3 innings in which he’s posted a 25-to-3 K/BB ratio.

As for Jepsen, he’s delivered strong bottom-line results since being acquired from the Angels in exchange for Matt Joyce (who has struggled in his new surroundings), but his peripheral stats have also taken a step back. Both his strikeout and walk rates are among the worst of his career, and while his 94.4 mph average fastball is strong, it’s down more than a full mile per hour when compared to his 2014 velocity. His swinging strike rate is down nearly three percent from 2014 as well.

Jepsen’s earning $3.025MM in 2015 and will get a raise this winter, so perhaps the Rays, faced with the possibility of paying a pair of relievers something in the vicinity of $5MM apiece, the team’s preference is to unload one of them right now. If that’s the case, moving Jepsen would be less detrimental to their 2015 chances than moving the more dominant and more controllable McGee.

Getting back to DeJesus and Jaso, both left-handed veterans are hitting reasonably well, though Jaso has spent most of the season on the disabled list. Each is a platoon player, with DeJesus having received just nine plate appearances against lefties all year. DeJesus has hit righties at a .270/.336/.395 clip, though, and he has a history of performing well when holding the platoon advantage. His contract contains a $5MM option for the 2016 season, so any team that picks him up could benefit from his services beyond this year.

Jaso only recently returned from a left wrist injury, but he’s shown no signs of ill effects at the plate. He’s mashed at a .359/.435/.538 clip thus far, and while that type of production clearly isn’t sustainable, Jaso has a very nice track record against right-handed pitching. He’s a career .275/.370/.428 hitter against righties and could help any club in need of help in that area. Jaso’s been a catcher for most of his career, but the Rays have used him at DH and in left field this year, as he does have multiple concussions in his past. He’s making $3.175MM in 2015 and is a free agent at the end of the year.

Earlier this week, Peter Gammons reported that there were as many as 16 clubs looking for bullpen help, so the Rays will have no shortage of trade partners. The Blue Jays, in particular, have been known to be hot after relief help. That’s also said to be the Twins’ top priority, and given the fact that Minnesota has an up-and-coming young core, adding a controllable arm such as McGee or Boxberger to supplement that group could hold appeal to them. The Pirates are reportedly working on a trade for a relief arm right now, with the other team in the mix not yet known. Jeff Todd and I discussed a number of AL teams looking to add relief help on yesterday’s podcast.

• Red Sox righty Jonathan Aro’s path to the big leagues was an unlikely one, Alex Speier of the Boston Globe writes. As a teenager, Aro twice contracted Dengue fever. He was already contemplating his life after baseball before finally signing at 20, a late age for a Dominican player, and for just $10K. “First of all, I signed as a 20-year-old. Secondly, I signed as a $10,000 guy. Thirdly, all the guys who signed in my class were high-dollar guys. I thought I was at the low end of the priority list,” says Aro through a translator. “So, in short, no — I didn’t think this was attainable.” Aro gradually made his way through the minors, though, and excelled for Double-A Portland and Triple-A Pawtucket this year, posting a combined 2.22 ERA with 9.9 K/9 and 2.2 BB/9 in 44 2/3 innings. He made his big-league debut Thursday.
• Rays lefty Drew Smyly will pitch from a mound for the first time on Saturday since heading to the disabled list in May with a torn labrum, Marc Topkin of the Tampa Bay Times tweets. In early May, it looked like Smyly was headed for season-ending surgery, but he currently appears set to rejoin the Rays at some point late this season.
• In other Rays injury news, DH John Jaso will start a rehab assignment Saturday with the Class A+ Charlotte Stone Crabs, Topkin tweets. Jaso has missed much of the season with a wrist injury. Jaso should provide the Rays with another reliable bat, although they’ve done well at DH this season, with Joey Butler and David DeJesus taking most the available plate appearances.

• While most teams are quick to name a closer, the Yankees are taking a wait-and-see approach, writes Andrew Simon of MLB.com. New York has two excellent but unproven options in right-hander Dellin Betances and southpaw Andrew Miller. Selecting a closer could come down to bullpen composition, said manager Joe Girardi. “I think it’s affected by possibly losing someone out of your bullpen to a starting role. That changes things. So we’ve got to figure that out first, then we put the rest of it together.” To me, this means that Miller is more likely to close if Adam Warren earns a gig in the rotation. Betances provided great value in multi-inning appearances last season. If Warren returns to the pen, the Yankees may prefer Miller to be available for tough left-handed hitters.
• The trickle down effect from Marcus Stroman’s season-ending injury could cause the Blue Jays to roster a third left-handed reliever, writes Gregor Chisholm of MLB.com. With Stroman out, prospect Aaron Sanchez is likely to make the rotation with lefty Brett Cecil filling in as the closer. Southpaw Aaron Loup is also expected to make the roster. Jeff Francis and Colt Hynes are internal options for the third lefty role. Externally, Cardinals reliever Sam Freeman and Nationals pitcher Xavier Cedeno were connected to the Mets earlier this evening.
• John Jaso suffered two concussions in the last two seasons that have put his career in jeopardy, writes Marc Topkin of the Tampa Bay Times. Presently, Jaso feels fine, but he’s unsure if he can catch. Per Jaso, “if they were to say, ’Here, catch tomorrow,’ I don’t know. That’s the scary part. Like I don’t know if I could take one, take 40 foul tips, what it would be…What I do know is that the longer I have between episodes, the stronger I’ll be. It’s letting the brain heal all the way again. You might think it’s gone, you might think you are all right, but it’s still there.“

• GM Brian Cashman said on WFAN Friday that the Yankees had finished their “heavy lifting” this offseason, Brendan Kuty of NJ.com notes. Previous reporting had indicated that the Yankees might pursue in James Shields, but Cashman’s comments indicate that isn’t the case. As Kuty suggests, the idea that the Yankees won’t be a top bidder for Shields is consistent with their approach to the offseason so far — they re-signed Chase Headley and added Andrew Miller, but they’ve otherwise steered clear of top free agents after adding Jacoby Ellsbury, Masahiro Tanaka, Brian McCann and Carlos Beltran last offseason.
• Wilmer Flores isn’t listening to criticism about the Mets’ shortstop situation, Matt Ehalt of the Record writes. The Mets didn’t add a shortstop this winter and are heading into the spring with Flores as their likely starter, leading to plenty of second-guessing from commentators and fans. “People doubt a lot of people,” says Flores. “I’m not worried about that. I’m just going to go out and play.” Flores hit .251/.286/.378 last season, but he’s hit well in the high minors, and the Mets like his offensive potential. His defense remains open to question, although UZR has liked his glove work in small sample sizes in his first two partial seasons in the Majors. As Mike Petriello wrote for Fangraphs last month, concerns about the Mets’ shortstop situation might be somewhat misplaced. The position is weak throughout the Majors, and Steamer projects Flores will be the 19th most valuable shortstop by WAR in the big leagues in 2015, ahead of some of the top options available this offseason, like Asdrubal Cabrera and Stephen Drew.
