The Rays optioned Kuhnel to Triple-A Durham on Wednesday.
EDGE Analysis
Kuhnel tossed two scoreless innings out of the bullpen in Tuesday's 4-3 loss to the Cardinals and was unlikely to be available for another day or two, so he was an easy choice for the Rays to move off the active roster to clear room for right-hander Drew Rasmussen (elbow), who was reinstated from the 60-day injured list in a corresponding move. The 29-year-old right-hander will head back to Durham after making a pair of two-inning appearances in relief following his July 30 promotion.
