Glen Perkins coughed up an eighth-inning lead and took the loss yesterday afternoon against the Rangers and rather than travel with the Twins to New York he stayed in Minnesota to undergo an MRI exam on his sore arm
Rhett Bollinger of MLB.com reports that no structural damage was found and Perkins has been diagnosed with forearm inflammation.
Perkins thrived moving from the rotation to the bullpen last season, adding several miles per hour to his fastball and dominating in the first half, but he seemed to wear down late in the season and has allowed five runs in five outings this year.
He signed a $10.3 million contract extension last month and is by far the best reliever in a Twins bullpen that was the worst in baseball last year. In his absence Brian Duensing and Jared Burton will be used to set up closer Matt Capps, which could get ugly versus the Yankees’ lineup.
