White Sox placed RHP Luis Castillo on the 15-day injured list with right shoulder impingement.

Castillo’s velocity issues suggest he’s been dealing with this for a spell, but it probably didn’t help decided to suddenly turn him into a reliever and use him on one day of a rest Tuesday. He still could potentially see some postseason time, but he ends the regular season 4-11 with a 5.85 ERA in 130 2/3 innings. He’s owed $22.75 million next year in the final season of a five-year contract.
