White Sox Claim Onelki Garcia, Designate Ronald Belisario, Outright Jared Mitchell

The White Sox have designated reliever Ronald Belisario for assignment, Paul Sullivan of the Chicago Tribune reports on Twitter. The club also claimed lefty Onelki Garcia from the Dodgers and outrighted outfielder Jared Mitchell, per the Tribune’s Colleen Kane (Twitter links).

Garcia is an intriguing pick-up for Chicago. The 25-year-old has only limited big league experience, but has already racked up over a year of service time due to injury. But he has one solid season under his belt in the upper minors, back in 2012, and his live arm was intriguing enough that Baseball America rated him the Dodgers’ ninth-best prospect heading into 2014 in spite of his having undergone an elbow procedure. As BA wrote, the Cuban has a big fastball and good curve with plenty of upside if he can improve his control and add polish.

Belisario, 31, spent some time as Chicago’s closer in his first season with the Pale Hose, but he struggled overall. The former Dodger pitched to a 5.56 ERA with 6.4 K/9 and 2.4 BB/9 in 66 1/3 innings. However, Belisario’s FIP and SIERA feel that he was markedly better than his ERA. Indeed, much of those struggles seem to have come from a fluke 57.7 percent strand rate — significantly lower than his career mark of 70 percent. Belisario was also plagued by a .339 BABIP despite having posted a .288 mark for his career in that department. There were some positives to his game this past season, including an average fastball velocity of 93.9 mph and a strong 59.3 percent ground-ball rate. Nonetheless, Chicago apparently wasn’t comfortable with his projected arbitration salary of $3.9MM.

Mitchell, 26, was the Sox’ No. 1 pick back in 2009 (23rd overall) and ranked among the game’s Top 100 prospects according to both Baseball America and Baseball Prospectus that offseason. However, the LSU product has yet to show the offense one would hope for from a first-round outfielder, as he’s batted just .219/.341/.348 in parts of three seasons at the Triple-A level.
