Lackey getting closer

John Lackey had another throwing session on flat ground, pitching at about medium speed before Monday's game. Manager Mike Scioscia said he expects Lackey to throw from a mound at some point in the middle of this week. It will be the first time the-right-hander has thrown from a mound since spring training. An MRI on March 14 confirmed that Lackey had a strained right triceps.
