• Veteran outfielder Chris Denorfia has been released from his minor league contract with the Giants, according to Henry Schulman of the San Francisco Chronicle (Twitter link). Denorfia, 36, signed with San Francisco back in early June and batted .269/.329/.408 in 143 plate appearances across two levels (most of the time spent in Triple-A) before his release. He’s a veteran of 10 big league seasons and is a career .272/.330/.392 hitter at the Major League level.
• The Dodgers released infielder/outfielder Zach Walters following his DFA on Sunday, reports J.P. Hoornstra of the Los Angeles News Group (Twitter link). Walters received just five big league plate appearances with the Dodgers this season but slashed a respectable .276/.326/.444 in 366 plate appearances at the Triple-A level. Walters has plenty of pop, as evidenced by his 10 big league homers in just 181 plate appearances, but he’s also struck out in 36 percent of his trips to the plate as a Major Leaguer. Still, as a player with power and experience at shortstop, second base, third base and in the outfield, the 26-year-old switch-hitter figures to draw interest elsewhere.
• Right-hander Jeff Ferrell, who was designated for assignment by the Tigers last week, was released by Detroit yesterday, tweets Evan Woodbery of MLive.com. The 25-year-old entered the season as Detroit’s No. 21 prospect, per Baseball America, but he hasn’t pitched since May due to injury. Last season, Ferrell notched a 2.58 ERA with 10.6 K/9 and 2.1 BB/9 in 38 1/3 innings at the Double-A level.
• Outfielder Darin Mastroianni has signed a minor league contract with the Rangers, reports Mike Berardino of the St. Paul Pioneer Press (via Twitter). Mastroianni, 30, had a nice season as a fourth outfielder for the Twins back in 2012 but battled an ankle injury the following season and ultimately was designated for assignment in 2014. He’s bounced around the league on a number of waiver claims minor league deals since that time, making brief MLB appearances with the Blue Jays and with the Twins (in a second stint). The fleet-footed Mastroianni is a career .271/.341/.349 with 87 steals in 108 tries across 369 games.
• The Marlins released infielder Pedro Ciriaco, per Baseball America’s Matt Eddy. Miami acquired Ciriaco from the Rangers back on July 8 in exchange for lefty Eric Jokisch (who had been designated for assignment), but he hit just .221/.239/.250 in 68 plate appearances with Triple-A New Orleans. The versatile 30-year-old has plenty of big league experience under his belt, having compiled a .268/.294/.368 slash in 649 plate appearances across 272 Major League games from 2010-15.

• The Twins have released outfielder Darin Mastroianni, Mike Berardino of the Pioneer Press tweets. Mastroianni briefly played in the big leagues for the Twins earlier this season, but they outrighted him last month. The 30-year-old has batted just .256/.327/.300 in 203 plate appearances at Triple-A Rochester this season. As Berardino notes, the Twins recently optioned Byron Buxton to Rochester, and he figures to play center field there, leaving Mastroianni without much of a role. In parts of five big-league seasons with the Blue Jays and Twins, Mastroianni has batted .206/.271/.280 in 317 plate appearances.

As Phil Miller of the Minneapolis Star Tribune notes, Mastroianni now has 72 hours to accept an assignment to the Twins’ Triple-A affiliate.  He could elect free agency since he has been outrighted before (in September 2014 by the Blue Jays) but as Mike Berardino of the St. Paul Pioneer Press reports, Mastroianni is believed to be staying in the Twins organization.

Mastroianni signed a minor league deal with Minnesota last winter and appeared in seven games with the big club before hitting the DL.  Over his career, Mastroianni has a .206/.271/.280 slash line over 317 PA and 25 steals in 29 attempts.  All of his big league experience has come with the Twins and Blue Jays (in two separate stint with each team) and he has also played in the Phillies’ and Nationals’ farm systems.

O’Rourke, 28, made his MLB debut with the Twins last season and worked to a 6.14 ERA in 22 innings. He received another 7 1/3 innings this season and allowed four earned runs in that time. O’Rourke has picked up 29 strikeouts in his 29 1/3 big league innings, but he’s also issued 18 unintentional walks (20 total), hit a batter and thrown four wild pitches, demonstrating that his control leaves something to be desired. To his credit, lefties have mustered an abysmal .149/.286/.234 line against him in his brief time in the Majors, so perhaps a club in need of a left-handed specialist could harbor some interest.

12:59pm: The Twins will designate right-handed reliever J.R. Graham for assignment and select the contracts of outfielder Darin Mastroianni and catcher Juan Centeno, reports La Velle E. Neal III of the Minneapolis Star Tribune (links to Twitter). The disappointing Twins appear poised for a significant slate of roster moves today, though the club has yet to formally announce the full litany of moves. Last night, Mike Berardino of the St. Paul Pioneer Press reported that Tommy Milone and Casey Fien were to be placed on outright waivers.

The 26-year-old Graham was Minnesota’s selection in the 2014 Rule 5 Draft, and the Twins carried him on the roster for the entirety of the 2015 season in order to retain the rights to the former Braves top prospect in spite of a 4.95 ERA in 63 2/3 innings. Graham, though, has been shelled at the Triple-A level this season, surrendering 10 runs on 11 hits and seven walks with seven strikeouts in just 8 1/3 innings. He matched that 10.80 ERA in his brief promotion to the Majors, yielding a pair of runs on three hits and a walk with two strikeouts in 1 2/3 innings.

The addition of Mastroianni and Centeno comes with some noteworthiness as well. The pair will presumably fill two of the 40-man roster spots that were vacated by the placement of Milone and Fien on waivers. Perhaps more notable than the duo’s addition to the roster itself is the likely implications carried by their promotion; Centeno’s addition means that offseason trade acquisition John Ryan Murphy, who has begun the season in a dreadful 3-for-40 slide, will be optioned to the minors, writes Neal’s colleague Phil Miller.

Why did they prefer Upton to Cespedes? Well, in part (link), the Tigers loved Upton’s consistent demeanor and his personality.  Upton also came with the endorsement of Alan Trammell and Kirk Gibson.  When all was said and done, Upton agreed to a six-year, $132.75MM deal with Detroit and Cespedes stayed with the Mets on a three-year deal that will allow him to opt out after year one.

Here’s more from the AL Central:

• Some Indians fans have been critical of the team’s decision to sign Mike Napoli, Rajai Davis, Juan Uribe, and Marlon Byrd (minor league deal) to one-year pacts rather than make one high-priced free agent splash this winter.  Terry Pluto of The Plain Dealer explained the Tribe’s thinking a little bit while pointing out the pitfalls of pricey multi-year deals, like the ones given to Nick Swisher and Michael Bourn.  The Indians wound up committing ~$104MM to both players and recently they had to trade both veterans to try and unload a portion of that money.
• Carlos Quentin has a June 1st opt-out in his deal with the Twins, assistant GM Rob Antony tells Mike Berardino of the Pioneer Press (on Twitter).  However, there’s also a “gentleman’s agreement” to cut him loose prior to that date if the team does not have big league plans for him.  Quentin appeared destined for retirement before he had a change of heart during the offseason.
• Ryan Sweeney has a straight minor-league deal with no opt-out clause or right to demand his release, Antony tells Berardino (on Twitter).  Sweeney sat out the 2015 season in an effort to allow his body to heal from multiple ailments.  While he was out of the game, the veteran collected on the $2MM still owed to him by the Cubs.
• Outfielder Darin Mastroianni also has a straight minor-league deal with the Twins, according to Berardino (Twitter link). The assistant GM says that the 30-year-old (31 in August) didn’t even ask the club for an opt-out due to his comfort with team brass.  Mastroianni signed on with Minnesota in December.

• The Red Sox announced that they’ve re-signed right-hander Anthony Varvaro to a minor league contract. Additionally, they announced the signings of outfielder Ryan LaMarre (as WEEI’s Rob Bradford first reported), catcher Ali Solis, infielder Chris Dominguez and right-hander William Cuevas to minor league deals. Of that group, Varvaro, LaMarre and Dominguez played in the Majors last season, with Varvaro logging 11 innings in the Boston bullpen. The 31-year-old Varvaro has seen Major League action in each season dating back to 2010, highlighted by 128 innings of 2.74 ERA ball for the Braves from 2013-14. LaMarre, 27, made his big league debut with the Reds last season and appeared in 21 games but recorded just 26 plate appearances. Dominguez, 29, also received a brief look from Cincinnati in 2015 and got a similar cup of coffee with the 2014 Giants. Boston also confirmed its previously reported signing of veteran right-hander Sean O’Sullivan on a minors pact.

Earlier Updates

• Among the Twins’ recent minor league signees are outfielder Darin Mastroianni, shortstop Wilfredo Tovar, and righty Brandon Kintzler, MLB.com’s Rhett Bollinger tweets. The 30-year-old Mastroianni failed to crack the majors last year for the first time in four seasons, and slashed just .257/.308/.345 in 484 Triple-A plate appearances. Tovar, 24, had spent his entire career in the Mets organization and put up a .283/.327/.356 batting line last year over 388 turns at bat in his first run at the highest level of the minors. Injuries have limited Kintzler, who is 31. He only threw 29 1/3 innings at all levels last year after contributing 135 1/3 major league innings of 2.93 ERA pitching over 2013-14.
• The Padres have signed backstop Erik Kratz to a minor league deal, Dennis Lin of the San Diego Union-Tribune recently reported on Twitter. Kratz, 35, only saw 28 MLB plate appearances last year but provides another depth piece for a San Diego club that has numerous options behind the dish.

It seems likely that the Nats’ interest in Mastroianni relates to their recent loss of Reed Johnson to surgery. The team has top prospect Michael Taylor available to serve as a right-handed-hitting, center-field-capable bench option, but probably prefers that he receive everyday playing time with Denard Span back in the lineup. (It doesn’t hurt, of course, that Taylor won’t accrue service time while at Triple-A.)

It remains to be seen whether Mastroianni will head right to the big league roster. The fleet-footed 29-year-old has four seasons and 306 plate appearances under his belt at the MLB level. This year, at Triple-A, he has slashed .293/.333/.362 over 64 turns at bat.

The list of announced players is as follows:

• Infielder Andres Blanco
• Outfielder Brian Bogusevic
• Infielder/outfielder Russ Canzler
• Infielder/outfielder Chase d’Arnaud
• Outfielder Jeff Francoeur
• Catcher John Hester
• Outfielder Darin Mastroianni
• Outfielder Xavier Paul

Every player on that list has MLB experience, and many have fairly extensive time in the bigs. Francoeur, of course, is a former top prospect and long-time starter who spent time both playing in the outfield and pitching last year in the Padres organization. He is one of several signees who could provide options if the Phillies were to move any of their current outfielders. The infield-capable members of this list may create some flexibility as well.

At various times, all of Marlon Byrd, Ben Revere, and Domonic Brown have found their names as rumored trade candidates. Though shortstop Jimmy Rollins and, to a lesser extent, second baseman Chase Utley have both been named as potential trade chips as well, those players enjoy full no-trade protection and appear less likely to be dealt.

• The Mets have released Juan Urbina, reports Baseball America’s Matt Eddy (via Twitter). In five years with the Mets, the 21-year-old left-handed pitcher failed to pass Low-A ball. While he generally posted strong strikeout rates in limited work, he walked nearly the same number of hitters. The once-prospect signed for $1.2MM in 2009 and is the son of former big leaguer Ugueth Urbina.
• The Phillies have signed outfielders Brian Bogusevic and Darin Mastroianni to minor league deals. Bogusevic last appeared in the big leagues in 2013 and spent last season hitting .260/.349/.411 in 311 plate appearances for Triple-A New Orleans in the Marlins system. Mastroianni appeared briefly for the Twins and Blue Jays in 2014 but spent most of the season with Triple-A Buffalo, hitting .267/.349/.369 in 393 plate appearances.
• The Blue Jays have re-signed righty Bobby Korecky. The 35-year-old had a strong season in the Buffalo bullpen, posting a 1.97 ERA with 8.4 K/9 and 2.5 BB/9 in 64 innings.
• The Athletics have signed righty Kevin Whelan, who briefly appeared with the Tigers in 2014 and a 2.70 ERA with 11.2 K/9 and 4.4 BB/9 in 43 1/3 innings with Triple-A Toledo.
• The Royals have signed 24-year-old corner infielder Balbino Fuenmayor, who hit .347/.383/.610 in 413 plate appearances with Quebec in the Canadian-American Association, earning BA’s Indy League Player Of The Year award. The Blue Jays released Fuenmayor in 2013.
• Cubs outfielder Ryan Kalish, White Sox outfielder Michael Taylor and Phillies shortstop Andres Blanco have all elected free agency. All three players were recently outrighted.
• The Tigers have re-signed third baseman Mike Hessman. The 36-year-old Hessman has gotten few chances in the big leagues, but he’s still a feared slugger in the International League, where he hit 28 home runs and batted .248/.330/.500 in 2014. The veteran has 417 career minor league home runs, including 307 at the Triple-A level.

• 1B Daric Barton (Athletics), OF Tyler Colvin (Giants), OF Justin Maxwell (Royals), SP Jair Jurrjens (Rockies), RP Wilton Lopez (Rockies) and R Troy Patton (Padres) have all elected free agency, Baseball America’s Matt Eddy tweets.
• Seven former Blue Jays have elected free agency, Eddy tweets. Among them is first baseman Dan Johnson, who the Jays outrighted earlier this week. Johnson collected 48 plate appearances in Toronto this season, but spent most of the year with Triple-A Buffalo, hitting .232/.381/.434 in 459 plate appearances there. The others who elected free agency are shortstop Jonathan Diaz, outfielders Cole Gillespie and Darin Mastroianni, and pitchers Bobby Korecky, Brad Mills and Raul Valdes.

• The Blue Jays have outrighted outfielder Darin Mastroianni and corner infielder Matt Hague, according to the International League transactions page. Both 29-year-olds were designated on the 2nd in order to clear roster space for the team’s September call-ups. Mastroianni struggled in limited action in Toronto this year. Hague, meanwhile, has yet to see much of a chance at the MLB level but posted solid numbers at Triple-A this year.

The 40-man moves create space for the selection of top prospect Dalton Pompey’s contract, the selection of veteran George Kottaras’ contract and the reinstatement of Brandon Morrow from the 60-day disabled list. Additionally, Toronto has activated Dan Johnson from the DL and recalled Ryan Goins, Anthony Gose, Kendall Graveman, Sean Nolin and Daniel Norris from Triple-A.

Mastroianni, 29, hit .156/.156/.250 in 32 plate appearances with the Blue Jays after they claimed him on waivers from the Twins earlier this season. The Jays had lost Mastroianni to the Twins on waivers two years prior, and the speedster looked to have carved out a spot for himself in Minnesota as a fourth outfielder following a solid .252/.328/.350 batting line in 77 games. However, a series of ankle injuries kept Mastroianni off the field, and he’s yet to again show the respectable bat and plus speed that made him an asset in that 2012 season.

Hague, also 29, has posted strong Triple-A numbers this season between the Pirates and Blue Jays organizations. He’s totaled a .282/.371/.465 batting line with 15 homers in his fourth season at that level. Hague has never received an extended look in the Majors, though the first baseman does have 76 PA in the bigs. He’s hit just .222/.263/.250 in that limited chance, however.

Wagner underwent Tommy John surgery in August, which will likely sideline him for the majority of the 2015 season. He was a reasonably effective bullpen piece for the Jays in 2013, posting a 3.79 ERA with 7.8 K/9 and 3.1 BB/9 in 38 innings. Those numbers aren’t too dissimilar from his career marks at Triple-A, where he’s posted a 3.91 ERA with a superior 10.1 K/9 and a 3.3 BB/9 rate.

Mastroianni originally came to Minnesota from the Jays via waiver claim in February of 2012, as Mike Berardino of the St. Paul Pioneer Press notes on Twitter. The 28-year-old has not produced much in limited MLB time since,: he possesses a .220/.228/.295 career line, virtually all of which has come with the Twins. Mastroianni is known for his ability to get on base: he has a lifetime .372 OBP at both the Double-A and Triple-A level, having spent parts of four seasons at each.

Wilson, 24, has yet to see time in the bigs or the highest level of the minors. He is off to a slow start at Double-A (.210/.239/.306 in 68 plate appearances) after putting up a .259/.333/.375 line with 16 stolen bases in 242 plate appearances in his first stint at that level last year. Wilson opened the year at the 22nd spot on Baseball America’s list of the team’s prospects. The speedy center fielder is said to have starter upside if he can translate his tools into production.

Fuld, 32, appeared in just seven games for the A’s, hitting .200/.273/.433 in 33 plate appearances. He has a career .233/.312/.334 line in 841 career plate appearances, most of them with the Rays and Cubs. He signed a minor league deal with Oakland in February and made the team out of Spring Training when fellow defensively-savvy outfielder Craig Gentry was injured. Fuld became expendable with a healthy Gentry, who returned to the A’s lineup last week, and Coco Crisp, but he’ll be joining a Twins squad which badly needs outfield depth.

“He can steal a base. He’s a good defender. Puts together pretty good at-bats,” Twins assistant general manager Rob Antony said of Fuld (as quoted by Mike Berardino of the Pioneer Press). “He’s not a power guy. He is a gamer, a guy who comes to play everyday. Hopefully he can add a little life to the offense and (Twins manager Ron Gardenhire) can use him in different spots in the outfield as well.”

To make room for Fuld on the 40-man and 25-man roster, the Twins announced they have designated outfielder Darin Mastroianni for assignment. Mastroianni has gone 0-for-11 with five strikeouts in seven games since having his contract selected from Rochester on April 10th. The Twins now have 10 days to either trade, release, or outright the 28-year-old, who can opt for free agency instead of accepting a minor league assignment since he has been outrighted previously (per a Berardino tweet). Berardino notes this move may not have been necessary had Jason Bartlett’s retirement been finalized one day sooner with the Easter weekend also working against the Twins.

Zach Links contributed to this post.

Mastroianni made his MLB debut with the 2011 Blue Jays after spending most of the season at Double-A and Triple-A. The 26-year-old posted a .268/.353/.377 line with 34 stolen bases (44 attempts) in the upper minors last year. He has minor league experience at all three outfield positions and has mostly played center field.
