GOODYEAR, Ariz. -- The Cleveland Indians will place centerfielder Michael Bourn on the disabled list before their opener at Oakland on March 31.
Bourn may miss only four regular-season games because of the injury, a tight left hamstring. Outfielder Nyjer Morgan was told by general manager Chris Antonetti and manager Terry Francona that he will be on the Indians' opening-day roster.
Bourn felt discomfort on March 16 while running from first to third against San Francisco. He has been undergoing treatment and has started strength exercises.
Morgan was signed to a minor league contract by the Indians on Jan. 16. He spent last season in Japan with Yokohoma. Cleveland told third baseman Lonnie Chisenhall he will join the team for its opener.
The Indians optioned right-handers Chen-Chang Lee and Trevor Bauer to Triple-A Columbus on Monday and assigned infielders David Cooper and Bryan LaHair to their minor league camp. Right-hander Aaron Harang was given his unconditional release.
