The Hawks took Brian Falkenborg off the active roster today with discomfort in his right shoulder.
Falkenborg had similar problems with his right shoulder earlier this season and was taken off the active roster on May 18. He returned a little over a month later on June 22 and pitched an inning in relief on June 26 (vs Orix). At some point between then and today, Falkenborg tossed a bullpen session and felt some discomfort in his right shoulder.
The Hawks called up Levi Romero to take Falkenborg's spot on the active roster.
