After allowing a big homer, Ken Giles took out his frustration on his own face

The Yankees beat the Astros on Tuesday, 4-0, largely in part to a big three-run homer off the bat of Gary Sanchez in the ninth. 
That blast came off Astros reliever Ken Giles, who came in after eight masterful innings from Justin Verlander. Giles, however, didn't have as much luck on the evening, and wound up taking the loss.
After being lifted from the game by manager A.J. Hinch, Giles couldn't help but take out some of his frustration ... on himself as he walked toward the dugout:

We've all been there -- or at least felt that type of personal frustration -- before. 
"I screwed up a win," Giles told MLB.com's Brian McTaggart after the game. "We should have won this game. We should have bounced back. I didn't give our team a chance. Of course I'm going to be frustrated with that. This team deserves the best out of everybody and they need me to be the best I can be. They deserve that and that's what I'm going to give them from here on out."
