O's likely to make roster move to replenish bullpen

PITTSBURGH -- The Orioles look poised to make a roster move following Chris Tillman's three-out start in Wednesday's 9-8 loss to the Pirates to help replenish a bullpen that was already a man down.

"It's hard to tell until we get our arms around it tonight. I'm not going to give you right now who it is," manager Buck Showalter said of the reliever that was unavailable and could potentially be a disabled list situation. "You can probably figure it out because they didn't pitch. Some things crop up during the day. That's why so many times, things may look one way going into the day, and then by the time BP and the game's over, you've got a different situation, and you've got to adjust."

If it's not a DL move, the Orioles will have to make room on the roster. Right-hander Brad Brach has Minor League options and he threw four scoreless innings after Tillman, so he won't be available to pitch for a few days. Triple-A Norfolk's T.J. McFarland is a candidate to come up and add length, as he last pitched on Saturday.

"I'd like to keep [Brach] if I can," Showalter said. "I think he's thrown 48 [pitches] this year, and today, he was [one] less than that. I think it's the innings more than the pitch count. I know if I asked him what he'd say."
