Before Wednesday's 3-2 victory over the Detroit Tigers, Piazza said he was curious to see if he could still handle duties behind the plate if his right shoulder improves enough for him to try it.
Piazza, signed by the A's in the offseason to be a full-time DH, sprained his right shoulder May 2 but has swung the bat very well since returning from the DL on July 20.
That the A's are interested in having Piazza available to catch is nothing new. But Piazza sounds more enthusiastic about the idea than he has in the past.
"It's just frustrating. My arm wasn't in great shape before I got hurt, and now it's not coming around like they hoped," Piazza said. "But they indicated they'd still like me to do that. So if I can ... I'd like to."
With rookie Kurt Suzuki handling the starting job and Rob Bowen in place as his backup, the A's don't appear in desperate need of Piazza catching. But Piazza has continued throwing all the while and the team hasn't given up hope he'd be able to catch.
Piazza said he might even try going through some catching drills before Friday's game against the Los Angeles Angels.
"It's just step by step," he said. "We'll pretty much see what I can tolerate. I haven't exactly thrown to bases, just some long toss."
The A's original plan was to have him stay on the DL for a prolonged period to see if he could build up his shoulder and double as a catcher
The plan was eventually scrapped, and Piazza has said that he was never fully behind the idea.
But he knows that catching is a way to get him and Jack Cust, who also sees time at DH, in the lineup at the same time. Plus, he's simply curious to see if he can still man the position where he spent the first 14-plus years of his career.
"One thing I don't want to do (if he does catch) is not throw well enough, or injure it further," he said.
Aside from his shoulder, Piazza is confident it wouldn't be tough readjusting to the physical demands of catching.
"Physically I'll be OK," he said. "It will still take some time, but your instincts take over."
Though the A's held on to Piazza as Tuesday's non-waiver trade deadline passed, they could still deal him if he were to clear waivers without being claimed by another team.
