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.
