The Astros designated Velazquez for assignment Thursday.
Velazquez will end up as the necessary roster casualty needed to make room for Raynel Delgado, who was recalled from Triple-A Sugar Land on Thursday. Velazquez went 0-for-4 with a sacrifice fly during his 10-day stint with the Astros but owns a .764 OPS across 163 plate appearances in the minors this season.
