Giles has saved 61 games for the Astros but was wildly inconsistent during the team's 2017 World Series run, posting an uncharacteristic 11.74 ERA.
The Astros announced that they had optioned Giles down to Triple-A Fresno. It has been a season of woe so far for Giles, whom the Astros have entrusted the closer role. But Giles has memorably sunk the "Stros in high-leverage spots this season".
Giles was not happy after manager A.J. Hinch took him out of the game after he allowed three hits to three straight batters to start the inning. Given a three-run lead in the ninth inning, Giles allowed three consecutive singles to open the frame before being pulled by manager A.J. Hinch. Hinch declined to talk about the specifics of the incident.
Setting Tuesday night's foot stomping aside, this is one in what has been a line of problematic appearances for the former closer.
More importantly, it looks like hitters have figured him out. Nearly more memorable than that was Giles punching himself in the face after giving up four runs to the Yankees in the ninth inning on May 2. The sweeping slider that was often Giles's strikeout pitch has none of the snap it had last year, leaving hitters to sit on his fastball, which has velocity, but doesn't appear to have almost as much movement as in previous years.
He was removed from Houston's Tuesday night win against the A's in favor of Hector Rondon to applause from the Minute Maid Park crowd.
Perez, 22, has never pitched in an Major League Baseball game.
