AUG. 20: The White Sox have requested unconditional release waivers on Leesman, tweets Colleen Kane of the Chicago Tribune.
AUG. 16: The White Sox have designated lefty Charlie Leesman for assignment in a flurry of roster moves, Dan Hayes of CSN Chicago tweets. The White Sox also activated Avisail Garcia, moved Moises Sierra (oblique) to the disabled list, promoted Eric Surkamp and moved Javy Guerra to the bereavement list. Garcia, the key return in last year’s Jake Peavy trade, has not played in the big leagues since April due to a labrum injury. His surgery was previously believed to be season-ending, so he’s coming back ahead of schedule.
Leesman, 27, has only appeared in one game for the White Sox this season, an April start in which he only averaged 86.5 MPH on his fastball. He has, however, proven to be a good pitcher at the Triple-A level. He performed well at Triple-A Charlotte in 2012 and 2013 and has pitched 68 innings there this season, posting a 4.10 ERA, 8.7 K/9 and 4.2 BB/9.
