CHICAGO — The Chicago White Sox acquired right-hander Miguel Castro in a trade with the Houston Astros on Friday.
Castro and infielder Vinny Capra were added to the roster before the opener of a three-game series against the Chicago Cubs. Capra was claimed off waivers from Milwaukee on Thursday.
To make room on the roster, the White Sox optioned left-hander Jared Shuster to Triple-A Charlotte, and infielder Jacob Amaya was designated for assignment.
The White Sox traded international signing bonus pool money to Houston for Castro, who signed a minor league deal with the Astros on Dec.
