The Houston Astros announced Wednesday that they have optioned reliever Ken Giles to Triple-A one day after he hurled an expletive at manager A.J. Hinch when he pulled him from a game.

The Astros have recalled left-hander Cionel Perez in a corresponding move.

Hinch pulled Giles in the ninth inning of Tuesday's 6-5 win over the Oakland Athletics at Minute Maid Park after the righty closer gave up two hits without recording an out. Giles appeared to say, "F--k you, man," to Hinch as he handed him the ball.
