CLEVELAND -- Indians pitcher Jake Westbrook is back on the disabled list for the second time this season with an inflamed right elbow.
Westbrook was sent to the DL retroactive to Thursday, the day after he was activated to start against the Chicago White Sox. He is 1-2 with a 3.12 ERA in five starts this season and was on the DL from April 20 to May 28 with a strained muscle in his left side.
Mastny didn't have a decision and had a 10.80 ERA in two appearances for Cleveland before he was optioned to the Bisons on May 11. The right-hander went 1-0 with a 3.14 ERA in 11 appearances for Buffalo.
The Indians recalled reliever Jensen Lewis to take Westbrook's place on the roster. Lewis is 0-2 with a 3.58 ERA in 20 appearances this season for Cleveland. He was optioned to Triple-A Buffalo on May 24.
