Indians reliever Vinnie Pestano has been placed on the 15-day disabled list because of right elbow tendinitis.

Lefty reliever Nick Hagadone was recalled from Class AAA Columbus.

Pestano's stint on the DL is retroactive to May 1, meaning he is eligible to be activated May 16.

Pestano, who has not pitched in a game since April 28, threw on flat ground for about 10 minutes Sunday morning in front of manager Terry Francona and head trainer Lonnie Soloff. How Pestano felt coming out of the session seemingly would go a long way toward determining if he needed to be placed on the DL.

After the Tribe lost to Minnesota, 4-2, Sunday afternoon, Francona was optimistic that Pestano would avoid being shelved.

"He had a real good session,'' Francona said, "and everything points toward him being OK for (tonight).''

The outlook changed, however, when Pestano failed to get through normal batting practice throwing activities this afternoon without discomfort. Pestano had appeared and sounded anything but upbeat as he prepared to partake in BP.

The Indians begin a four-game series against the Athletics tonight at Progressive Field.

Pestano, who also threw Saturday, said Sunday morning: "We're still working through things. There's a lot of variables.''
