MLB Daily Dish April 10: Josh Hamilton, Matt Moore, Ervin Santana, Addison Russell

After a relatively quiet day on Tuesday, a flurry of roster moves and signings took place across the majors on Wednesday. We've got it covered for you:

Injuries

• Los Angeles Angels outfielder Josh Hamilton will undergo thumb surgery, the team announced on Wednesday. Hamilton, who is batting .444 with a league-leading 1.286 OPS, was placed on the 15-day DL after being diagnosed with a torn ulnar collateral ligament and capsule in his left thumb. He is expected to miss 6-8 weeks, with outfielder J.B. Shuck being recalled from Triple-A to fill in during Hamilton's absence.

• The Tampa Bay Times' Marc Tompkin reported that Rays left-hander Matt Moore underwent tests on his UCL, with manager Joe Maddon stating that it's "not a slam dunk surgery right now." Further details should surface today. UPDATE: The Tampa Tribune's Roger Mooney wrote:

Further testing on Matt Moore's left elbow Wednesday revealed a tear in the ulnar collateral ligament. The Rays and Moore are deciding on the next step, which is either surgery or rehabilitation.

• Chicago White Sox outfielder Avisail Garcia left Wednesday's game after attempting a diving catch in the sixth inning. Garcia reportedly jammed his left shoulder, though X-rays came back negative, according to the Chicago Sun-Times' Daryl Van Schouwen. The Sox outfielder will be re-evaluated on Thursday.

• Miami Marlins starter Jacob Turner has been placed on the 15-day DL with a right shoulder strain, the team reported, with the move retroactive to April 4. Right-hander Arquimedes Caminero was recalled from Triple-A New Orleans to fill the vacant roster spot.

• Oakland A's top prospect Addison Russell will miss at least a month after suffering a torn right hamstring, reported Yahoo Sports' Jeff Passan. The injury is a grade three strain, meaning the A's will be careful to avoid rushing Russell back to action too quickly.

• The Minnesota Twins placed outfielder Oswaldo Arcia on the 15-Day DL, according to MLB.com's Rhett Bollinger. The team will recall Darin Mastroianni from Triple-A Rochester, where the outfielder is hitting .450 in 20 at-bats this season.

• The Seattle Mariners announced that they placed left-hander James Paxton on the 15-Day DL, recalling left-handed reliever Lucas Luetge from Triple-A Tacoma to fill in during Paxton's absence.

Roster Moves

• Atlanta Braves pitcher Ervin Santana made his first start of the season after being recalled from Triple-A Gwinnett. The right-hander shut out the Mets over eight dominant innings, allowing three hits and no walks. He threw only 88 pitches (65 strikes) in the outing as the Braves beat the Mets, 4-3.

• The Cleveland Indians recalled starter Trevor Bauer from Triple-A Columbus on Wednesday. The right-hander started the second leg of the team's doubleheader on Wednesday, putting up a solid pitching line despite taking the loss:

• The Boston Red Sox optioned right-hander Brandon Workman to Triple-A Pawtucket, according to the team's Twitter account. The move makes room for left-handed reliever Craig Breslow to join the big league club after a rehab stint in the minors, while Workman will likely assume starting duties at Triple-A.

• The Texas Rangers purchased the contract of third baseman Kevin Kouzmanoff, according to the Dallas Morning News' Evan Grant. The team designated right-handed pitcher Seth Rosin for assignment to make room for Kouzmanoff. A career .255 hitter, Kouzmanoff last appeared in the majors in 2011.

• The New York Yankees optioned catcher Austin Romine to Triple-A Scranton, recalling right-handed pitcher Shane Greene, according to Examiner.com's Dan Pfeiffer.

• The Kansas City Royals were busy on Wednesday. The team recalled second baseman Johnny Giavotella from Triple-A Omaha, activated right-handed reliever Louis Coleman from the 15-day DL, optioning starter Aaron Brooks and left-handed reliever Donnie Joseph to Triple-A to make room for Giavotella and Coleman.

• The Colorado Rockies recalled infielder Josh Rutledge, optioning right-handed reliever Wilton Lopez to Triple-A, per the Rockies PR department.

• The Toronto Blue Jays recalled right-handed reliever Neil Wagner from Triple-A Buffalo, optioning right-hander Marcus Walden to Triple-A, the team announced.

• The Los Angeles Dodgers activated starter Josh Beckett from the 15-Day DL and optioned right-hander Jose Dominguez to Triple-A Albuquerque, the team announced. Beckett started the Dodger's matchup against the Tigers on Wednesday night, allowing five runs (four earned) in four innings.

Signings

• The Kansas City Royals agreed to a minor league deal with right-hander Kameron Loe, via our own Chris Cotillo. He'll report to Triple-A Omaha, and the deal reportedly includes a June 15 opt-out clause. With Luke Hochevar going down earlier this season, the Royals might need to call on Loe to bolster their bullpen, assuming he shows some consistency in the minors.

Miscellaneous

• Pittsburgh Pirates starter Jeff Locke pitched in a rehab assignment at High-A Bradenton. The left-hander went six strong innings, allowing a pair of runs on five hits, a walk and 10 strikeouts, via TribLIVE.com's Rob Biertempfel.

• Pedro Alvarez and Russell Martin each homered twice as the Pirates downed the Cubs, 7-5.

• Angels starter Garrett Richards surrendered just one hit over seven shutout innings as Los Angeles blanked Seattle, 2-0.
