Uehara to undergo MRI

SARASOTA, Fla. -- Koji Uehara will undergo an MRI either Wednesday or Thursday to rule out any other possibility on his left leg or lower back other than the left hamstring strain he was diagnosed with.

Uehara exited the Orioles' game on March 18 game against the Blue Jays with a left hamstring strain and hasn't thrown on the mound since suffering the injury. The right-hander said Monday that he expects to start the season on the disabled list, given that there are limited opportunities to throw before Opening Day on Tuesday.

Manager Dave Trembley has said previously that Uehara would have to be able to show he can throw by mid-week to avoid the DL. Prior to Wednesday's game, Trembley acknowledged that Uehara will not be on the team's Opening Day roster.

"I can't honestly say that he will break camp ready to go," Trembley said. "I think it's too late for that to happen."

A former starter, Uehara played light catch on Wednesday. The Japanese right-hander has no timetable for when he will get back up on the mound.
