The White Sox announced that they have placed lefty Derek Holland on release waivers. Chicago announced a series of other moves as well. Top prospect Yoan Moncada has been activated from the DL, while the team purchased the contract of lefty Jace Fry and brought him up from Double-A.

Holland will almost certainly clear waivers, in which case he’d return to the open market while the remainder of his $6MM annual salary remains on Chicago’s books. Though he can still sign with another organization, so long as one is willing to free up a 40-man spot, Holland would not be eligible to pitch in the postseason.

The 30-year-old southpaw simply has not had quite the bounceback season he and the Sox hoped for when he signed on over the winter. Holland has managed only a 6.20 ERA over 135 innings, allowing 31 long balls while carrying 6.9 K/9 against 5.0 BB/9 in that span.

If there’s something to build off of, it’s the fact that Holland has been available all year after dealing with significant injuries in recent campaigns. Still, he averaged just 91.7 mph on his fastball, well off his career average of around 94. A variety of other underlying indicators suggest that hitters weren’t having much trouble seeing what was coming their way. For instance, Holland coaxed batters to offer at pitches outside the zone just one quarter of the time while surrendering 38.4% hard contact — both representing career-worst figures.
