Cardinals closer Trevor Rosenthal will have Tommy John surgery. The team announced the decision Wednesday after moving the hard-throwing right-hander from the 10-day disabled list to the 60-day DL.
Rosenthal, who had 93 saves in 2014-15, lost the closer's job a year ago to Oh, but reclaimed it this season after Oh struggled. Rosenthal recorded 11 saves this season, giving him 118 over the past four years.
