Prior to Monday's series opener against the Houston Astros, the Chicago White Sox announced a few roster moves. The club reinstated right-handed pitcher Vince Velasquez from the 15-day IL. In a corresponding move, the White Sox optioned right-handed pitcher Matt Foster to Triple-A Charlotte.
Vince Velasquez has been on the injured list since July 6 due to a blister on one of his pitching fingers. He began a rehab assignment with the Charlotte Knights on August 1. Velasquez holds a 5.21 ERA with 42 strikeouts and 16 walks over 46.2 innings pitched for the White Sox. He has worked in the starting rotation and out of the bullpen this season. During his rehab assignment, he worked exclusively out of the bullpen.
Matt Foster, who finds himself the odd man out of the Chicago White Sox bullpen, has struggled of late. The right-hander has walked six hitters in his last nine relief appearances while only striking out three during that span. While he sports a rather low 3.38 ERA over those nine outings, his command hasn't been as strong as it has been during various stretches of the season.
