The Indians will put Bourn on the DL before their opener March 31 at Oakland. The Indians did not want to rush Bourn back in light of the surgery. - Cleveland Indians center fielder Michael Bourn will start the season on the disabled list because of a tight left hamstring, though he could return within the first week. Bourn had surgery on the hamstring in October. It's unfortunate what is happening with Michael,'' Morgan said. 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. He felt discomfort on March 16 while running from first to third against San Francisco, and has been undergoing treatment and started strength exercises.
