The White Sox have outrighted first baseman Casey Gillaspie, per a club announcement. That opens a spot on the 40-man roster that has yet to be filled.

Gillaspie, a former first-round pick of the Rays back in 2014, was acquired last summer in the deal that sent Dan Jennings to Tampa Bay. The South Siders placed Gillaspie on the 40-man roster over the offseason to protect him from the Rule 5 draft.

Since the start of 2017, however, the switch-hitting Gillaspie has mostly struggled. He is off to a miserable .214/.263/.229 start at the plate this year at Triple-A Charlotte, with 29 strikeouts and no home runs through 76 trips to the dish.
