"I'm really ready for August to be over," Pestano said. "I've just never been this disgusted and embarrassed with myself than in the past two weeks. You go from four and a half months grinding it out to [giving] it away in three or four appearances.
"It's pretty embarrassing. I'm just not being able to locate anything. I'm having no feel for either pitch. It's getting pretty old."
On the season, Pestano has gone 3-1 with a 2.08 ERA in 56 appearances, piling up 62 strikeouts against 21 walks over 56 1/3 innings. Along the way, the right-hander has collected a Major League-leading 33 holds, which is also a single-season club record.
Pestano's performance has lagged of late, though.
Over his last five relief outings, Pestano has surrendered six runs on eight hits over 5 1/3 innings, posting a 10.13 ERA and allowing a .348 opponents' average in that span. In Wednesday's 8-4 loss, the setup man yielded two runs on three hits in the eighth inning, helping the A's take a four-run lead.
It was a discouraging turn for Pestano, especially considering Cleveland has dropped 26 of its past 31 games.
"It's just frustrating. I don't have the words," Pestano said. "I know for a fact that I've never been in this position before, to go on this bad of a stretch. It just [stinks]. It takes the wind out of you. You can talk all you want. For the first four and a half months of the season, I can say whatever I want to say and do whatever I want to do.
"What it comes down to is, when the team's needed me the most, over the past two weeks, I haven't gotten the job done. That's not acceptable."
