Braden likely out until September

Foot improving, but hurler needs time to build arm strength

OAKLAND -- A's left-hander Dallas Braden hasn't pitched since July 31 because of a rash/infection on his left foot, and it's killing him.

The inactivity, that is. The foot is getting better every day.

"It's a grind," Braden said of being on the disabled list. "You know me. I'm not a do-nothing kind of guy."

Braden isn't exactly doing nothing. In fact, he's doing all he can to get back onto the active roster. But he's already missed a few turns in the rotation, and he'll miss at least a couple more while working to build his arm strength back up.

"It'll be a while," Oakland manager Bob Geren said Tuesday before the second game of a three-game series against the visiting Yankees at Oakland-Alameda County Coliseum. "Once he gets on the mound, it could be another five, 10 days after that."

Before Braden is cleared to return to the roster, he'll have to throw a bullpen session or two, pitch in a simulated game and possibly make a Minor League rehab start.

"I doubt [his return] will be this month," Geren said.

Braden, who is 8-9 with a 3.89 ERA in a career-high 22 starts this season, struggled while trying to pitch through the discomfort in his foot, allowing 12 earned runs in his final two starts before being placed on the DL.

Prior to that, he'd been the most consistent starter on the A's staff. Braden, 25, went 7-7 with a 3.13 ERA before the All-Star break despite consistently ranking at the bottom of the American League in run support.

"Dallas has been everything we hoped he'd be and more," Geren said of his Opening Night starter. "Hopefully we can get him back here pretty soon and he can finish the season pitching the way he's been pitching for us all year."
