Rays' Adam Kolarek: Expected to be called up Friday

Kolarek is expected to be called up from Triple-A Durham on Friday, Marc Topkin of the Tampa Bay Times reports.

Kolarek had a rocky introduction to the big leagues earlier this season, generating a 5.87 ERA over 11 appearances with the Rays. The 28-year-old has been outstanding with the Bulls, however, as evidenced by a 1.65 ERA and 46:16 K:BB over 43.1 innings. He'll give manager Kevin Cash another left-handed option out of the bullpen during the Rays' playoff push.
