• The Cubs announced that lefty Brian Duensing has cleared waivers and been sent outright to Triple-A Iowa. He has enough service time to reject the assignment and still retain the entirety of this year’s $3.5MM salary, but there’s no indication yet whether he’ll choose to do so. The 36-year-old Duensing had a strong year with the 2017 Cubs but was clobbered for a 7.65 ERA in 37 2/3 innings last season after signing a two-year, $7MM contract to remain in Chicago. His second season with the Cubs saw him walk more batters (29) than he struck out (24), and his struggles continued into Spring Training, where he yielded eight runs in seven innings of work.
• Infielder Stevie Wilkerson was outrighted to Triple-A Norfolk after clearing waivers, per an announcement from the Orioles. The 27-year-old made his big league debut a year ago and hit .174/.224/.239 in 49 trips to the plate with the O’s. The versatile Wilkerson has experience at every position other than catcher and center field. He’s a career .266/.342/.368 hitter in parts of five minor league seasons.
• The Giants announced Thursday that left-handed reliever Steven Okert has been outrighted to Triple-A Sacramento after clearing waivers. Okert, 27, has spent time in the Giants’ bullpen in each of the past three seasons and compiled a career 4.28 ERA with 8.2 K/9 against 2.8 BB/9 in 48 1/3 innings as a Major League reliever. He’ll remain with the organization as a depth option should the club need to call upon some additional left-handed bullpen help at some point in the 2019 season.

Collins hit the open market Friday when the Twins released him, ending a short stay with the team that signed him to a minors pact in early February. The 29-year-old, who broke in as a quality reliever with the Royals back in 2011, has barely seen action in recent seasons on account of significant injury troubles (including multiple Tommy John surgeries). But Collins did return to the majors last year for the first time since 2014 and accrue 22 2/3 innings as a member of the Nationals, with whom he logged unspectacular numbers (4.37 ERA/5.76 FIP with 8.34 K/9 and 4.76 BB/9). Collins was neither tough on lefties nor righties last year in the majors, though he did perform well at the Triple-A level, where he put up a 3.94 ERA/2.71 FIP with 9.56 K/9 against 4.22 BB/9.

Collins will give the Cubs some lefty relief depth behind Mike Montgomery and along with the injured Xavier Cedeno. Duensing had been filling that role, and it’s possible he’ll continue to if he stays in the organization. The 36-year-old would first have to get through waivers unclaimed, which is a distinct possibility given that he’s due a $3.5MM salary this season. Duensing’s set to close out a two-year, $7MM contract, which he earned entering 2018 on the heels of a standout season in Chicago. Unfortunately for the two parties, though, Duensing struggled to a disastrous 7.65 ERA/6.35 FIP with equally unappealing strikeout and walk rates (5.73 K/9, 6.93 BB/9) in 37 2/3 frames last year.

• Yu Darvish, Hamels’s former rotation mate in Texas, has already been declared out for the rest of the 2018 season. He addressed that fact with reporters today, with MLB.com’s Carrie Muskat among those on hand. The veteran righty says he felt all along “there was something else other than the tightness” he was experiencing in his pitching arm, so much so that the diagnosis of a stress reaction came as something of a relief. Darvish indicated that he’s not even thinking about the season to come so much as he is trying to care for his ailing arm. Still, he expressed confidence that he’ll bounce back and be “stronger going forward.” That’ll obviously be the hope of the Cubs organization, which still has $101MM invested in Darvish after the present season.
• The club also announced today that righty Tyler Chatwood is headed to the DL with hip soreness, as Mark Gonzales of the Chicago Tribune covers. He’ll be replaced on the roster by Dillon Maples, for the time being, with Alec Mills set to come up to start tomorrow. Chatwood has been plagued by walks all year long, racking up 93 to go with his 85 strikeouts over 101 2/3 innings. That’s simply not a manageable rate of free passes, as his 5.22 ERA reflects. Details of the new malady remain scant, but it certainly seems there are good reasons for the club to find cause to give Chatwood a breather regardless.
• Another major recent open-market signee, Brandon Morrow, has performed as hoped when he has been available. But the closer has been sidelined for over a month with a balky elbow and still lacks a clear timeline. He went in for a checkup today, says Muskat. That examination evidently did not reveal anything of particular note, though it was not arranged due to any fear of a setback. It seems the hope remains that Morrow will return at some point in the final month of the regular season.
• In other Chicago reliever news, Brian Duensing — yet another hurler who signed with the Cubs in free agency last winter — is headed for a rehab assignment. The 35-year-old southpaw, who carries an ugly 7.34 ERA on the year, has been on the shelf for the past several weeks with a shoulder ailment.

More from around the National League…

• In Muskat’s piece, Kris Bryant also gets a mention. The former MVP reportedly had a good day in the batting cages on Friday and is nearing a return from the DL. Bryant’s been sidelined since June 23rd with shoulder inflammation, and the Cubs have anxiously been hoping to get him healthy again and back in the lineup. P.J. Mooney of The Athletic reports on Twitter that Bryant is heading to the Cubs’ AA affiliate to begin his rehab assignment; he’ll be joined by lefty Brian Duensing. Mooney also notes that righty Anthony Bass is headed to the DL due to an illness; fellow righty James Norwood will take his place, making his first trip to the big leagues.
• The Padres still believe in the offensive potential of elite defensive backstop Austin Hedges, says AJ Cassavell of MLB.com. But they’re more than happy with the value he’s providing them with from behind the plate. Manager Andy Green had this to say on the subject: “We’re patient on the offensive side, because we see the value on the defensive side.” Hedges was right at the Mendoza line on the season with a .200 average entering play today, and his OPS sat south of .600 as well.
• Breakout Dodgers slugger Max Muncy has been tearing it up this season, with an ISO of .347 to go with an 18.9% walk rate. But he almost didn’t play baseball at all this year, as Tim Brown of Yahoo Sports chronicles. Following his release by the A’s last season, Muncy was looking into how many classes it would take to complete his business degree. “You start experiencing failure and you don’t know if you’re as good as you thought you were. Mentally I wasn’t doing as good as I should have been. And then, last year was a chance for me to regroup and recover and focus on myself,” Muncy said. “I could just focus on baseball, remembering how much I love the game and how much I liked playing it. For me, that was the biggest thing.” Now, of course, things have turned around to an extraordinary level, and Muncy is practically a lock for his first All-Star selection.

Now for the latest on a pair of NL Central teams:

• As the July 31 non-waiver trade deadline approaches, the Brewers are “open to every possibility,” according to GM David Stearns (via Tom Haudricourt of the Milwaukee Journal Sentinel). With his team in first place in the NL Central by 1 1/2 games, Stearns is “highly motivated” to make improvements, writes Haudricourt, who notes that the Brewers could opt for a high-profile addition to their lineup instead of their rotation. That could be Machado, who’d be a massive upgrade for a Brewers team that hasn’t gotten much from the shortstop position this year and sent Orlando Arcia to the minors Sunday. Machado’s not under contract beyond this season, though, and as a result, Haudricourt doesn’t expect the Brewers to end up with him.
• The Cubs announced that they’ve placed reliever Brian Duensing on the 10-day disabled list and recalled right-hander Dillon Maples from Triple-A Iowa. The left-handed Duensing is dealing with fatigue in his pitching shoulder, which continues a less-than-ideal season for the 35-year-old. After Duensing posted an outstanding 2017 with the Cubs, they re-signed him to a two-year, $7MM deal in the offseason. The investment hasn’t paid off so far, though, as Duensing has logged a bloated 6.92 ERA with horrid strikeout and walk rates (5.88 K/9, 6.92 BB/9) in 26 innings.

With a couple months left until the start of the season, the Mariners could still complement Hernandez & Co. with more starting help – payroll’s “not an issue,” according to CEO John Stanton. However, if we’re to take Dipoto’s word, it doesn’t seem likely. “We are doing the best we can to develop our system, not to clog it,” Dipoto said. “Could we go out and sign a free agent that would be better than our current fifth starter? Absolutely. Would that be the best thing for the present of the Mariners? Maybe. Would it be the best thing through the wider lens for the present and future of the Mariners? Probably not. We’ll be able to address those needs as we go. Because the one thing we’ve not had to deal with here is a lack of resources.”

More on a couple other West Coast clubs:

• In search of left-handed relief help, the Athletics “made some offers to some guys; we just weren’t able to get them here,” manager Bob Melvin informed Jane Lee of MLB.com and other reporters Saturday (Twitter link). One offer went to Brian Duensing, who turned down a deal worth $3MM more than the two-year, $7MM pact he took to re-up with the Cubs, Susan Slusser of the San Francisco Chronicle reports. The A’s also attempted to pick up outfielder Austin Jackson on a one-year deal, but the Giants reeled him in with a two-year, $6MM contract. Now, Oakland’s not discussing any “significant free agents,” Slusser writes.
• Andrew Baggarly of The Athletic has an excellent, free-to-read piece on new Giants hitting coach Alonzo Powell, who was diagnosed with prostate cancer Jan. 2 and will undergo prostate removal surgery on Tuesday. Powell’s support system includes his wife, Jana, as well as both the San Francisco and Houston organizations (he was the Astros’ assistant hitting coach from 2015-17), which Baggarly details. The Giants have been invaluable to Powell, as they took over his medical care after scans showed his cancer had spread to his bones. Had that been accurate, surgery would not have been an option for Powell, who would have instead had to go through a year of chemotherapy and radiation. But the Giants’ chief internist, Dr. Robert Murray, was skeptical of those results, and he had Powell undergo another bone scan that ultimately returned good news. After his surgery, Powell will need “daily radiation treatments for several weeks,” Baggarly writes, but the hope is he’ll be with the Giants when their pitchers and catchers report to spring training Feb. 13. We join those around the game in rooting for Powell to achieve that goal.

11:05am: Duensing has passed his physical, as the team has now formally announced his two-year contract. Chicago’s 40-man roster now sits at 39 players.

JANUARY 17: The Cubs have agreed to a two-year deal to bring back lefty Brian Duensing, according to Jon Heyman of Fan Rag (via Twitter). If finalized, it’ll guarantee the southpaw $7MM, per the report. Duensing is a client of the Legacy Agency.

Duensing, who’ll turn 35 years of age before the start of the 2018 season, was targeted by the Cubs last winter. He justified the team’s faith, turning in a quality season on a $2MM salary. Evidently, Duensing also enjoyed his time at Wrigley; per Heyman (via Twitter), Duensing had the chance to earn “significantly more” with other organizations this winter but chose instead to return.

Despite his encroaching age, the results certainly justify the contract. Duensing is fresh off of a 62 1/3-inning campaign in which he carried a 2.74 ERA with 8.8 K/9 and 2.6 BB/9. He also allowed just one earned run on one hit in his five postseason appearances.

In many ways, Duensing’s 2017 work represented a continuation of his typical efforts, as he sat in his usual range of fastball velocity (92 to 93 mph) and continued to bring a starter’s arsenal to bear in the bullpen. He continued a trend in pitch usage, utilizing his offspeed mix (slider/curve/change) more than half the time for the first time in his career, but generally continued down a path he had already embarked upon.

Duensing has generally been tough to square up as a reliever, holding opposing hitters to a .254/.322/.372 slash when he enters from the pen. He was reliable against both lefties and righties in 2017, but he has done that at times previously. Duensing’s 10.3% swinging-strike rate last year was the second highest mark in his career, though that fell mostly in line with prior output. And he carried a solid 48.6% groundball rate in 2017 that doesn’t stand out from his career average, either.

In large part, then, credit is due to the Cubs for recognizing Duensing as an under-appreciated hurler, rather than tweaking his approach. The team will hope that the success can continue even as he continues to age. While the expectation will presumably remain that Duensing will work in a relief role, perhaps it doesn’t hurt that he has a background as (and, as noted, continues to use the pitch mix of) a starter.

Dipoto, of course, has become known for his sheer volume of moves, which perhaps stands out all the more in a market setting that is still mostly on ice. Here’s the latest:

• The Cubs are “not done” and are focused especially on the pitching staff, president of baseball operations Theo Epstein said today (via ESPNChicago.com’s Jesse Rogers). He said it’s still possible the organization will pursue “depth moves” or that it will add “another real quality pitcher.” Is free agent Jake Arrieta still a possibility? “We’ve never ruled anything out with him,” says Epstein, as MLB.com’s Carrie Muskat tweets.
• Chicago is said to be among a handful or more of teams still in the hunt for top free agent starter Yu Darvish, who has himself added intrigue to the market with some comments from his Twitter account. After musing recently on a mystery team, Darvish again took to the airwaves today to address the interest of the Yankees. After first suggesting the team had not made him an offer, the veteran righty then tweeted he had received one — but that “the numbers are not correct.” That said, MLB.com’s Bryan Hoch reports (via Twitter) that New York has not, in fact, put together a contract proposal for Darvish. The Yanks have long seemed a lurking but less-than-perfect potential suitor, given the team’s interest in staying below the luxury tax line this year.
• Meanwhile, the Athletics seem to be targeting a lefty in the bullpen, as John Shea of the San Francisco Chronicle reports. Per Shea, Oakland has ongoing interest in Tony Watson and has also engaged Brian Duensing in talks. Both veteran free agents are among the best relievers still left on the open market. Indeed, it’s not hard at all to make the case that they are the two most appealing southpaws still looking for new homes.

Chicago inked Duensing to a then-surprising $2MM big league deal early in the 2016-17 offseason. While the 34-year-old had previously had some success out of the Twins’ bullpen, Duensing had a lackluster 2015 season in Minnesota and totaled just 13 1/3 innings in the Majors all of last year, logging a 4.05 ERA with the Orioles.

The Cubs, however, saw enough to pique their interest and have been rewarded with what now looks to be one of the best one-year, Major League contracts issued last winter. Through 61 1/3 innings out of the Chicago ’pen this year, Duensing has posted a 61-to-18 K/BB ratio and a 47.3 percent ground-ball rate en route to a 2.79 ERA. Duensing has relatively even splits versus lefties and righties, though his K/BB numbers are vastly superior against lefties and he’s traditionally had problems against right-handed bats.

As for Groome, the former No. 12 overall pick (2016) posted terrific numbers in three starts in the Low-A New York Penn League but has had more struggles in the Class-A South Atlantic League. Groome has missed bats at a high level in 2017 (11.7 K/9) but has averaged nearly five walks per nine innings and was a bit homer-prone when pitching in the more advanced of his two leagues this season (1.22 HR/9). He only just turned 19 last month, though, meaning he was routinely squaring off against considerably older and more experienced opponents.

Both switches are now reflected in MLBTR’s Agency Database, which contains representation info on more than 2,500 Major League and Minor League players. If you see any notable errors or omissions, let us know via email: mlbtrdatabase@gmail.com.

Settling for a one-year contract isn’t an ideal route for most free agents, but that doesn’t mean that those (relative) bargain pickups can’t bring significant on-field impact to the teams with which they sign. While none of the players on this list received all that much fanfare when signing, they’ve all provided some notable benefit to the teams that made these commitments:

• Kurt Suzuki, $1.5MM, Braves: Suzuki languished in free agency for several months as players like Jason Castro, Matt Wieters and Welington Castillo all generated more attention from teams and fans. However, it might be Suzuki that has provided the most bang for buck on last winter’s catching market. The 33-year-old has had a surprising career year in Atlanta, hitting .266/.344/.507 with 15 homers to date. Some have been quick to suggest that Atlanta’s new homer-happy stadium has benefited Suzuki, and while that may be true to an extent, he’s hit for more power on the road than at home. He’s put himself in position for a possible two-year deal this winter, but if he has to settle for one yet again, it should come at a higher rate.
• Adam Lind, $1.5MM, Nationals: An awful 2016 season and an overcrowded market for corner bats created some questions about whether Lind would have to settle for a minor league contract late last winter. He ultimately secured a guaranteed deal, but it came with just a $1MM base and a $500K buyout of a mutual option. For that meager commitment, he’s given the Nats 267 plate appearances with a .297/.352/.490 slash to go along with 11 homers. Like Suzuki, that might not land him a starting role, but it could land him multiple years as a complementary bench piece.
• Chris Iannetta, $1.5MM, Diamondbacks: Iannetta has not only rediscovered his power stroke in 2017 — he’s made it better than ever. The 34-year-old’s .249 ISO is a career best, and he’s slugged 14 homers. While that’s still four shy of his career-best with the 2008 Rockies, Iannetta’s 14 big flies this year have come in just 272 PAs, whereas he needed 407 to reach 18 back in ’08. He’s also bounced back from a down year in the framing department and been above average in that regard, per Baseball Prospectus.
• Jhoulys Chacin and Clayton Richard, $1.75MM each, Padres: The Friars signed four starters for $3MM or less last winter — Jered Weaver and Trevor Cahill being the others — and have received a combined 345 innings out of this pair. Chacin’s run-prevention (4.06 ERA) and strikeout rate (7.44 K/9) have been better, while Richard has 13 more innings (179 total), superior control (2.6 BB/9) and superior ground-ball tendencies (59.1 percent). Neither is going to be mistaken for much more than a back-of-the-rotation stabilizer, but both have done enough to garner larger commitments on the upcoming open market.
• Brian Duensing, $2MM, Cubs: I doubt I was alone in being surprised to see Duensing, 34, land a Major League deal last winter on the heels of a lackluster season in the Orioles organization. Duensing, though, has quietly been outstanding for the Cubs. In 54 2/3 innings, he’s logged a career-high 9.05 K/9 rate with 2.30 BB/9 and a 47 percent ground-ball rate en route to a 2.63 ERA. He’s held lefties in check reasonably well, but the first time in his career he’s also striking out right-handed batters at a lofty rate. In fact, the .211/.276/.317 that righties have posted against him is actually weaker than the .256/.300/.388 slash to which he’s limited left-handed bats.
• Matt Belisle, $2.05MM, Twins: Belisle’s inclusion is arguable; he’s posted a pedestrian 4.36 ERA with 8.55 K/9, 3.69 BB/9 and a 42.2 percent ground-ball rate. Those numbers are largely skewed by a putrid month of May, however. Since June 3, Belisle has a 2.25 ERA with nearly a strikeout per inning and improved control and ground-ball tendencies — all while stepping into higher and higher leverage roles. He’s now serving as the Twins’ closer and has a 1.54 ERA with a 29-to-5 K/BB ratio since July 1. He’ll be 38 next season, so the earning power here isn’t sky-high, but he’s probably earned a raise, barring a late collapse.
• Logan Morrison, $2.5MM, Rays: Few players have benefited more from one-year, “pillow” contracts in  recent memory than Morrison, who has parlayed his $2.5MM deal into a .248/.355/.529 batting line and a 36-homer season campaign to date. Morrison only just turned 30 years old, so he’ll have age on his side this winter as well. A three- or four-year deal seems plausible for Morrison even with the diminished recent market for corner bats.
• Alex Avila, $2.5MM, Tigers: Avila hasn’t been as excellent with the Cubs as he was with the Tigers, but he’s still among the league leaders in hard contact and exit velocity — both of which have beautifully complemented his always-terrific walk rate (15.9 percent in 2016). With 14 homers under his belt and a batting line that grades out roughly 25 percent better than the league average, per context-neutral metrics like OPS+ (124) and wRC+ (127), Avila could vie for a multi-year deal and/or a starting job this offseason.
• Joe Smith, $3MM, Blue Jays: Smith’s K/9 has nearly doubled, from 6.92 in 2016 to 11.86 in 2017, and he’s posted a dramatically improved 1.82 BB/9 this year as well. Smith has also served up just three homers in 49 1/3 innings of work, and his 3.10 ERA, while solid, is actually representative of some poor fortune in the estimation of fielding-independent metrics (1.97 FIP, 2.35 xFIP, 2.34 SIERA). He’ll be 34 next year but should top that $3MM mark and could net the second multi-year free-agent deal of his career.
• Andrew Cashner, $10MM, Rangers: MLBTR’s Jeff Todd recently took a more in-depth look at Cashner, noting that his strong 3.19 ERA isn’t backed up by his K/BB numbers. Cashner’s complete lack of missed bats — he has the lowest swinging-strike rate and second-lowest K/9 rate of qualified MLB starters — is going to limit his earning power. But, he’s undeniably been better than he was in 2016, his velocity is comparable to last season and he’s limited hard contact quite well. A multi-year deal is certainly a possibility this offseason.
• Carlos Gomez, $11.5MM, Rangers: Gomez’s production hasn’t reached the star levels it did in 2013-14, but he’s been a better performer at the plate this season. A spike in his OBP (from .298 to .337) is due largely to a massive increase in the number of pitches by which he’s been hit, which is less encouraging than if he’d upped his walk rate considerably. However, Gomez has also shown quite a bit more power in 2017 than he had in recent seasons (.208 ISO in ’17 vs. .153 in ’15-16 combined), and Defensive Runs Saved feels he’s improved in center field as well. Gomez won’t see the massive payday he looked to be on pace for after 2014, but he’s still young enough to notch a multi-year deal this winter.

Notable exceptions: Neither Welington Castillo nor Greg Holland is included on this list, though both have provided good value to their new teams (Castillo in particular). While their contracts are often referred to as one-year deals with a player option, that type of contract is no more a one-year deal than Jason Heyward’s eight-year, $184MM deal with a third-year opt-out is a three-year deal. Both players were guaranteed the possibility to be under contract for two years, and those agreements are considered two-year deals for the purposes of this list.

Jerry Blevins has also given the Mets terrific value on his one-year, $6.5MM deal, but the club option attached to that deal is a veritable lock to be exercised, so he’s unlikely to hit the free-agent market again following the season.

Here’s more from the NL Central:

• Cardinals GM John Mozeliak expressed some displeasure with recent comments from second baseman Kolten Wong, as ESPN.com’s Mark Saxon writes. Wong had stated rather forcefully that he was uninterested in sharing time at second — a possibility that has been discussed (externally, at least) due both to his continued struggles at the plate this spring and the presence of Jedd Gyorko. Though Wong softened his initial statement, making clear he wants to remain in St. Louis, Mozeliak said he felt the “comments were a little tough given the fact we have other players playing well.” The veteran executive took a measured tone, but made clear where the organization stands. “Starting Sunday, we’re playing to win,” he said. “Whenever a player is trying to accomplish something in spring training, that can’t be an excuse for why things aren’t going well.”
• Righty Drew Hutchison was officially removed from the battle for the Pirates’ final rotation spot, with the team announcing that he has been optioned to Triple-A. That leaves righties Trevor Williams and Tyler Glasnow fighting for the fifth starter’s job. Both reached the majors last year after strong showings in the upper minors, though neither established himself at the game’s highest level. The young hurlers have each staked their claim in differing ways this spring, with Williams posting a 2.63 ERA with a dozen strikeouts against just two walks over 13 2/3 frames and Glasnow racking up 23 Ks — but also allowing nine runs on 19 hits and six free passes — over his 14 1/3 innings.
• The Cubs have made their final Opening Day roster decisions, as Gordon Wittenmyer of the Chicago Sun-Times reports. Outfielder Matt Szczur and infielder Tommy La Stella are both slated for reserve roles. Szczur, who’s out of options, had been mentioned as a possible trade candidate had he ended up missing out on the Chicago roster. Meanwhile, lefty Brian Duensing will open the season on the DL after being slowed earlier in camp due to back spasms.

Duensing, 33, spent much of the 2016 season in the minors. But he performed rather well there — with a 2.23 ERA and 9.5 K/9 versus 1.7 BB/9 over 32 1/3 innings — and earned a late-season promotion with the Orioles. In fourteen appearances for Baltimore, Duensing allowed six earned runs on 13 hits while recording ten hits against three walks.

Chicago had a need on the southpaw side of its pen, particularly assuming that Mike Montgomery will become a part of the rotation. But it’s still a bit surprising to see the defending World Series champs place a bet on Duensing, who is perhaps best characterized as a steadily useful arm. Over his eight-year major league career — the vast bulk of which came with the Twins — he has allowed 4.13 earned per regulation game while striking out 5.9 and walking 2.9 batters per nine to go with a solid (but hardly world-beating 46.3% groundball rate).

[Related: Updated Baltimore Orioles Depth Chart]

The 29-year-old Despaigne was acquired in an offseason trade that sent Class-A righty Jean Cosme to the Padres. Despaigne totaled just 27 1/3 innings for the Orioles at the big league level, pitching to a 5.60 ERA with 5.6 K/9, 4.9 BB/9 and a 38.2 percent ground-ball rate. His work at the Triple-A level was considerably better, as the Cuban-born righty tossed 88 1/3 innings with 3.87 ERA, 7.1 K/9 and 2.8 BB/9. In total, Despaigne has a 4.84 ERA in 249 1/3 innings between the Orioles and Padres as a Major Leaguer.

Duensing, 33, hasn’t pitched since June 19 due to inflammation in his left elbow. The longtime Twin signed a minors pact with the O’s earlier this season and pitched just 6 2/3 innings before going down with his elbow ailment. Duensing will give manager Buck Showalter four lefties to choose from in his bullpen, as he’ll join brilliant closer Zach Britton, rookie Donnie Hart and Jayson Aquino in the relief corps. The former third-round pick carries a significant platoon split in his career, so he’s best deployed as a situational lefty. He’s held same-handed opponents to a .238/.289/.329 slash in 935 career plate appearances.

More on a few other pitchers:

• The Mariners promoted their top pitching prospect, Double-A reliever Edwin Diaz, and optioned fellow reliever Cody Martin to Triple-A Tacoma to make room, per a team announcement. Diaz, 22, has posted a sterling 2.21 ERA, 11.95 K/9 and 1.55 BB/9 in 40 2/3 innings this year. Most of those numbers came as a starter, but the Mariners decided to move Diaz to the bullpen early last month because they feel his ceiling as a reliever is higher. Diaz has a high-90s fastball out of the ’pen and has dominated in relief this season, writes The Seattle Times’ Ryan Divish. He’ll have a chance to earn a spot with the Mariners in the wake of veteran Joel Peralta’s designation for assignment earlier this week.
• Before lefty Brian Duensing agreed to a minor league deal with the Orioles last month, the Giants and Royals also pushed for his services, he told Roch Kubatko of MASNsports.com (Twitter link). Duensing became a free agent when he opted out of his contract with Kansas City in mid-May; as evidenced by Kansas City’s desire to re-sign Duensing, the defending World Series champions were obviously sorry to see him go.
• The Tigers’ Shane Greene made three of his four early season appearances as a starter before landing on the disabled list April 24 with a blister on his throwing hand. The right-hander is healthy again, but he will now come out of the bullpen, manager Brad Ausmus said (via Brendan Savage of MLive.com). “He’ll work out of the pen, probably sixth-seventh innings, right around there,” Ausmus stated. “Maybe eighth depending on who needs rest, who’s coming up, etc. He can work a couple innings. Availability will come into play but he can definitely work a couple of innings.” Prior to his injury, Greene put up a 6.28 ERA, 6.91 K/9 and 5.65 BB/9 in 14 1/3 innings. He worked almost exclusively as a starter last season (16 of 18 appearances), though his run prevention was even worse (6.88 ERA).

• Southpaw Andy Oliver has opted out of his contract with the Orioles, as Rich Dubroff of CSNmidatlantic.com tweets. The 28-year-old has received seven major league starts, all coming in 2010-11 with the Tigers. Over 34 2/3 frames at Triple-A Norfolk this year, Oliver had worked to a 2.08 ERA with 8.8 K/9 against 2.6 BB/9. That represents a big step forward for the former top prospect, who has issued 5.7 free passes per nine innings over his seven seasons in the minors.
• The Braves have acquired left-hander Jed Bradley from the Brewers in exchange for a player to be named later or cash considerations, the Brewers announced. Bradley, soon to turn 26, was the 15th overall pick in the 2011 draft but has never seen his career take off in the minors. He posted a 5.83 ERA between Double-A and Triple-A in 2015 and has struggled to a 6.20 ERA in 24 2/3 innings of work at the Double-A level this season. The Georgia Tech product was one of the game’s top 100 prospects heading into the 2012 season (per Baseball America and MLB.com), but it’s been quite some time since he’s been held in high regard as a prospect.
• The Twins inked outfielder Logan Schafer to a minor league contract, per MLB.com’s Rhett Bollinger (on Twitter). Schafer, not to be confused with former Twins outfielder Jordan Schafer (no relation), has spent his entire career prior to this season in the Brewers organization. He’s a lifetime .281/.338/.431 hitter in 277 games at the Triple-A level, but he’s struggled to a .212/.286/.319 batting line in 646 big league plate appearances. The 29-year-old recently took to the independent circuit after being cut loose by the Nationals in Spring Training and enjoyed a successful 17-game stint with the Atlantic League’s Lancaster BarnStormers. He’s already reported to Triple-A Rochester and will provide Minnesota with some organizational depth in the outfield, where he can play all three positions.
• Right-hander Deolis Guerra was outrighted to Triple-A Salt Lake by the Angels after clearing waivers, according to Alden Gonzalez of MLB.com (on Twitter).  The 27-year-old Guerra yielded four runs in 5 1/3 innings of relief for the Halos before being designated for assignment. Guerra doesn’t have much of a track record in the Majors, but he’s been dominant at the Triple-A level from 2015-16 between the Halos and Pirates, pitching to a 1.08 ERA in 41 2/3 innings of relief.
• Veteran left-hander Brian Duensing’s contract was selected by the Orioles yesterday, and he made his Baltimore debut last night, though the two runs he surrendered in an inning of work probably weren’t how he’d hoped to make his first impression. Duensing, 33, posted a 3.84 ERA in 190 innings of relief from 2013-15 with the Twins upon being moved to the bullpen on a full-time basis, but his strikeout rate fell off a cliff in his final season with Minnesota. He signed a minor league deal with Kansas City this winter but opted out of the deal after a strong showing with their Triple-A affiliate and quickly signed with Baltimore. With Brian Matusz out of the picture, Duensing could have a chance to lock down a spot as a lefty specialist in the Baltimore ’pen.
• The Phillies have released southpaw Bobby LaFromboise, tweets SB Nation’s Chris Cotillo. The 29-year-old had been pitching for Philadelphia’s Triple-A affiliate but limped to a 5.94 ERA in 16 2/3 innings of work there. That’s a noted departure from LaFromboise’s typically excellent work at the Triple-A level, and it’s worth noting that he’s pitched well in limited Major League action over the past two seasons with the Pirates, yielding just two runs on eight hits and a walk with a dozen strikeouts in a combined 11 2/3 innings of work.
