Ken Giles nearly blew a save Tuesday night. Then he blew a gasket. 

Then on Wednesday the Astros blew him out of the water. 

Giles was sent down to Triple-A Fresno, one day after giving up three straight singles to the Oakland Athletics. He was pulled by manager A.J. Hinch and appeared to utter an obscenity as he stormed off the mound.

Giles has been a poster boy of inconsistency all season. He has an 0-2 record and 4.99 ERA in 34 appearances. But he also has 31 strikeouts and 12 saves.

"We need to get him right," Hinch told multiple reporters before Wednesday's game. "He’s not right. We need to get him right mentally and physically.”

Reportedly he has groused about his role with the team, and Tuesday night's outburst was enough to bring about change. Cionel Perez was called up to take his spot on the roster. Perez was called up briefly recently but did not get in a game. 

Perez, a lefty, was 6-1 at Corpus Christi with a 1.98 ERA and 83 strikeouts in 68.1 innings.
