Swisher doesn't believe injury is severe
From Chronicle Staff Writer Susan Slusser
Fast one from the A's post-game clubhouse: Nick Swisher said the left hamstring strain he incurred in the first inning isn't that bad.
"I'm walking around, I'm fine,'' he said. "There's no wheelchair.''
He confirmed he did also roll his right ankle, too, when he put on the brakes rounding third, but that didn't bother him at all.
Manager Bob Geren said the A's will know more about Swisher's condition today and he said that Danny Putnam is likely to be in center field tonight.
Judging by Swisher's remarks, he won't be going on the DL, which would be a real relief for the A's, considering they have five men out already.
