As expected, the Orioles announced Wednesday that right-handed pitcher Koji Uehara will be placed on the 15-day disabled list with a strained left hamstring. The move is retroactive to May 24.
"Obviously it feels bad to go on the disabled list," Uehara said through translator Ji Won Bang. "But there's no disappointment."
Uehara's move to the DL is anything but a surprise. The O's rookie left his last start Saturday after the third inning with soreness in his left hamstring, an area that has pestered him for the better part of a decade.
So far this season, Uehara is 2-3 with a 4.09 ERA in nine starts for the Orioles. In 50.2 innings pitched he has allowed 23 earned runs.
Uehara said he plans to make himself ready for his next outing by taking part in some bullpen activities and conditioning drills. According to Orioles manager Dave Trembley, nobody knows his pitcher's nagging hamstring better than, well, Uehara.
"I think he says it best," Trembley said. "The condition of his hamstring is something he's had to live with for the last 10 years. It's there, I think he says it's a relationship he's had. I think it's something we need to manage. It's something we need to get better so that he can pitch deep into the season."
Though his hamstring has bothered him for a lot of his career, Uehara did say that his injury is "lighter than the one in Spring Training." He did not comment on when he plans to throw again.
Uehara was scheduled to start in Thursday's game against the Detroit Tigers. Trembley said he may make an announcement as to Thursday's starter after Wednesday's game.
