Early in his bullpen session in Tampa, while Aceves threw off a full mound, his strained lower back acted up. It's the second setback he's had since going on the disabled list May 12.
"They're going to have to look at every alternative that we have to see what's the quickest way to get him right," manager Joe Girardi said. "And those are discussions they'll probably have in the next couple days."
Girardi said Aceves, who is scheduled to see team doctor Christopher Ahmad in New York Tuesday, felt a problem after only a few pitches.
No debate from Posada
"I said, 'I'm going to give you a day' and he didn't argue with me,'' Girardi said, "so that tells me it's pretty sore."
Girardi didn't rule out bringing up a third catcher at some point this week.
Maybe, maybe not
Girardi said the bullpen's inconsistencies don't necessarily mean the Yankees will be pursuing a reliever before the July 31 non-waivers trade deadline.
"I think people are going to look at areas we struggle in and make assumptions that we need to try and tighten that up, but that could all work itself out by July 31,'' he said, "and then you might look at another area."
'Get off my mound'
"Organizations always look for creative ways to do things because the more money they bring in, the more they can spend on players, so I don't blame them," said Girardi, who added that signed T-shirts could be auctioned off for charity.
