Brewers' Sean Nolin: Undergoes Tommy John surgery

Nolin (elbow) had Tommy John surgery two weeks ago, Tom Haudricourt of the Milwaukee Journal Sentinel reports.

With a career ERA and WHIP of 6.89 and 1.79, the Brewers had decided that they wanted to convert Nolin to a bullpen role. This could very well help improve the longevity of his elbow upon his activation from the DL. A timeframe for Nolin's return should become known when he gets farther into the rehab process.
