Can We Stop Pitching Him, Please?

The Yanks are up 2-1 in the ALDS, no thanks to Felix Heredia, who came in with the team up 8-1 in the 9th and proceeded to hit two batters. He always does this! (Well, not this necessarily. But something bad. There are always skidmarks on the bedsheets after he gets pulled.) Why do we keep pitching this guy?(!?!!?) I know he's our only Lefty Specialist, but, I mean: his specialty is WALKING PEOPLE. C'mon, Joe. We love you, but keep Felix in the pen.
