BALTIMORE -- Orioles reliever Pedro Strop (lower back strain) threw a bullpen session Wednesday with pitching coach Rick Adair. Strop threw 20-25 pitches and said he was pain free.
"First couple of the throws on the mound in the [bullpen], I was kind of afraid a little bit, just thinking about it. But then after a couple of throws, I didn't feel anything, I just let it go and there was no pain at all," Strop said.
"Just getting the normal delivery and everything, and it feels good," he said.
Strop said he hasn't been told if he'll do a Minor League rehab assignment before he returns from the 15-day disabled list. He's eligible to return June 8.
The converted shortstop also took ground balls in the infield with Adair before Wednesday's game.
"That was like a drill, because I used to be a natural shortstop, so they wanted it to be like natural, arm-wise, and stuff like that," Strop said.
"You get used to your normal delivery, because it's something you don't have to think to do it, because it's natural from [when you were a] little kid, so that way you get to clear your mind instead of thinking about all those mechanics and stuff -- just bring your natural arm motion."
Strop joked with reporters that he doesn't think a move back to shortstop is in his future, because he doesn't know who would hit for him.
