Quick hits

• Double-A Erie closer Corey Knebel injured his left knee in Wednesday's SeaWolves game, but the injury doesn't appear to be a major one. He's considered day to day with patellar tendinitis.

• As expected, the Tigers had an evaluator in place to watch free-agent reliever Joel Hanrahan throw a showcase session on Thursday at the University of Tampa. Team president/general manager Dave Dombrowski told MLive.com last week that he expected to send somebody to watch Hanrahan, a former closer who last pitched for the Red Sox early last season before undergoing Tommy John surgery.
