Philadelphia Phillies left-hander Cliff Lee will not pitch again this season but will avoid surgery on his injured elbow, MLB.com reports.

Lee, on the 15-day disabled list with a Grade 2 flexor pronator strain, lasted only 2 2/3 innings in his most recent start on July 31. That was his third outing after returning from a two-month stay on the disabled list because of the same injury.
