BALTIMORE -- Trey Mancini was out of Friday's starting lineup, a night after fouling a ball off his left knee in the O's 7-5 loss to the Tigers.
Mancini, who remained in the game after the incident, was hobbling around the clubhouse on Friday.
"Trey is pretty sore today. Hopefully it's not very long," Orioles manager Buck Showalter said. "I could tell, he basically hit a line drive right off his lower kneecap. That hurt. It's one of those things, once get you off of it and sleep on it, he's real sore. I just left him back in one of the pools. Trying to shorten the life of the injury. He's sore. Hopefully he's available soon."
With Mark Trumbo on the disabled list and the O's already working with a three-man bench, having Mancini out is tough. The rookie, who hit cleanup Thursday, entered the day ranking second in the American League and sixth in baseball with a .403 average with runners in scoring position.
Mancini is batting .298 with 17 homers and 57 RBIs in 94 games.
"Yeah, he's obviously worth waiting on," Showalter said when asked if the short bench may force the O's to make a quicker decision on whether Mancini will head to the disabled list. "Probably be a decision we need to make [Saturday]. I think we will know more when it's managing. So, we are obviously a little short on the bench."
