Cintron placed on disabled list

O's shortstop strained left hamstring in seventh inning Monday

BALTIMORE -- The Orioles' shortstop rotation continues to revolve, as Baltimore placed Alex Cintron on the 15-day disabled list with a strained left hamstring Tuesday. To fill his spot, the club called up Freddie Bynum from Triple-A Norfolk.

Cintron injured his hamstring in the seventh inning of Monday night's 6-5 loss to the Royals. Cintron, who contributed a tie-breaking RBI double in the fifth, came up lame after beating out an infield single and then left the game.

"Exactly when I touched the bat, I felt like a pull a little bit, but it's not that bad," Cintron said. "I don't think it's something that's going to take like two months or something [to rehab] -- I think maybe 10 days and I'll be ready. But we need somebody else because we have no other options. First time in my career going to the DL, hopefully I'll be back for the second half."

Cintron was batting .275 with three doubles, one triple, one home run and seven RBIs in 26 games for the Orioles, and said he initially thought the injury was worse than it turned out to be. It was obviously a disappointment to Cintron, as he was beginning to shine at the shortstop position.

"I felt like I was getting in my rhythm," Cintron said. "I was getting comfortable enough. ... I was getting into a groove, making good plays, catching the ball, getting my hits.

"It's kind of frustrating after dealing with an elbow injury last year. I worked hard to come back, and now, for the first time, I have to go to the DL for my hamstring. I'll take it day-by-day and, like I said, there's a lot of games left, so I'm just looking forward to being healthy."

The injury marks yet another switch at shortstop for the Orioles, a position they've been unable to fill with a consistent everyday starter since Spring Training. Bynum, who was sent down to Norfolk on June 22 after batting .192 in 34 games with the Orioles, joins Brandon Fahey as one of the club's current options at shortstop after hitting .400 (6-for-15) in five games with the Tides.

"No matter what they say to you, it's always bitter," Bynum said. "When you get sent down, it's not a good thing, but things happen for a reason. Maybe that was part of the plan to get me going, and hopefully I [can] come back up here and stay. I don't like the reason I'm up here, but I'll try to help the team best I can."

The Orioles have been openly shopping for a solution to their shortstop dilemma, and manager Dave Trembley said Tuesday that process would continue.

"It happened in Spring Training, with so many guys getting hurt," Trembley said. "It has been a difficult project. I know [president of baseball operations Andy MacPhail] made [shortstop] a definite thing for a lot of our pro scouts and Major League scouts to go out and look. That's a priority. It's probably continuing a little bit quicker now because of what happened to Cintron last night."
