St. Louis(AP)-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.

“I think just the timing of it, being right in the middle of this race and the way my personal season had been taking shape and the way the team has been playing recently. Tough timing,” Rosenthal said. “It felt like we were getting in a groove, I was in a groove, and to kind of have this happen and take a piece away from a really good team is a little bit of a bummer.”

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.

“We hoped for better news,” Matheny said. “Somebody is going to have to step in. He was really throwing the ball well.”
