Jared Mitchell CF CWS 6 Hrs

The White Sox outrighted Mitchell to Triple-A Charlotte on Thursday, Colleen Kane of the Chicago Tribune reports.

Mitchell has not lived up to the potential that made him a first-round pick in 2009, so the White Sox decided his spot on the 40-man roster would be better used on a different player.

Ronald Belisario RP CWS 6 Hrs

The White Sox designated Belisario for assignment Thursday, Colleen Kane of the Chicago Tribune reports.

Belisario appeared in 62 games for the White Sox last season, but he posted a 5.56 ERA and 1.45 WHIP, so the club decided to remove him from the 40-man roster. It remains to be seen what his next step will be.

Onelki Garcia RP CWS 6 Hrs

The White Sox claimed Garcia off waivers from the Dodgers on Thursday, Colleen Kane of the Chicago Tribune reports.

Garcia appeared in just one game last season due to a longer-than-expected recovery from elbow surgery. He is an intriguing prospect, however, having struck out 71 batters and giving up just 49 hits in 64.2 minor league innings. Garcia will have an outside shot to earn a spot in the the White Sox' bullpen during spring training.

Josh Zeid RP DET 6 Hrs

Zeid (foot) was claimed off waivers by the Tigers on Thursday, Evan Drellich of the Houston Chronicle reports.

Zeid was knocked around the the tune of a 6.97 ERA in 23 appearances with the Astros last season, but he maintained a strikeout rate of 7.8 K/9 and trimmed his walk rate by nearly a full walk per nine innings (from 3.9 BB/9 to 3.0). The right-hander figures to compete for one of the team's final bullpen spots in spring training, assuming he's fully recovered from foot surgery.

Sean Coyle 2B BOS 8 Hrs

The Red Sox added Coyle to their 40-man roster Thursday, Sean McAdam of CSNNE.com reports.

A third-round pick in 2010, Coyle broke out at Double-A Portland in 2014, slashing .295/.371/.512 with 16 homers and 13 stolen bases in 97 games. He did benefit from a .362 BABIP, but the 22-year-old showed more than enough to warrant protection from the Rule 5 draft and could be an option for the big club late in 2015 if Pablo Sandoval signs elsewhere.

Yu Darvish SP TEX 8 Hrs

Darvish (elbow) will have his MRI postponed until early next week, Jeff Wilson of the Fort Worth Star-Telegram reports.

The reason for the delay is unknown, but it likely won't impact Darvish's offseason timetable. He's had the MRI scheduled for several weeks, and a clean bill of health will allow him to go forward with his usual offseason routine, which typically doesn't involve throwing until December.

Alex Hassan LF BAL 8 Hrs

Hassan was claimed off waivers by the Orioles on Thursday, Dan Connolly of the Baltimore Sun reports.

Baltimore attempted to claim Hassan, who spent last season with the Red Sox, last week but the Athletics beat them to it. However, after just a few days with the A's, Hassan was waived again, and Baltimore jumped at the chance to claim him. Hassan hit .287/.378/.426 with 55 RBI in 408 at-bats last season and can play both corner outfield spots, as well as first base.

Jon Niese SP NYM 9 Hrs

Niese's injury history has reduced the level of interest in him as a possible trade option by the Mets, the NY Daily News' Andy Martino reports.

Niese is slated to make $7, $9, $10, $11 million annually through 2018, with the final two years as club options, which on the face of it should be a trade friendly contract. However, his elbow and shoulder injuries has reduced interest in him, as the Mets look to possibly deal from their starting pitching depth to fill other holes.

Ryan Tepera RP TOR 9 Hrs

Tepera was added to the 40-man roster on Thursday, Ben Nicholson-Smith of Sportsnet reports.

In doing so, Tepera will be protected from being eligible for the Rule 5 draft. The 27-year-old, a 19th-round pick in 2009, spent last season at Triple-A Buffalo, going 7-3 with a 3.66 ERA in 64.0 innings. Tepera allowed just four home runs while striking out 67 batters and walking 24.

Yadiel Rivera SS MIL 10 Hrs

The Brewers added Rivera to their 40-man roster Thursday.

Rivera does not hit much, but he is known for his defensive abilities in the middle infield. He reached the Double-A level for the first time in 2014 and will likely open there next season.
