PORT CHARLOTTE, Fla. (AP) Tampa Bay Rays closer Brad Boxberger will miss at least eight weeks after having abdominal muscle surgery.

Manager Kevin Cash said Friday the American League saves leader had the operation in Philadelphia. There is no timetable for his return, but Cash says the team will have a better idea after the first four weeks of recovery.

Cash adds that the ''core muscle'' injury had been nagging Boxberger this spring and he needed to take care of it.

In 2015, Boxberger had 41 saves in 47 opportunities. The 27-year-old right-hander was 4-10 with a 3.71 ERA. He was an All-Star for the first time.

Cash did not name a closer to fill in for Boxberger. The team will distribute the role for now among Alex Colome, Xavier Cedeno, Danny Farquhar, Steve Geltz and Ryan Webb.
