Pirates Jason Grilli out for 4-8 weeks

Pittsburgh Pirates closer Jason Grilli will not be returning to the mound anytime soon.

Grilli was placed on the 15-day DL on July 23 after he was forced to exit the game the night before after suffering an apparent arm injury.

Grilli has been diagnosed with a strained right flexor tendon and will be out 4-8 weeks.

The diagnosis came from Dr. James Andrews. Grilli does not need surgery at this time, but he will be re-evaluated in 10-14 days.

It’s obviously a big blow for the Pirates, who have the second-best winning percentage in baseball behind the Cardinals.

Mark Melancon will continue to close while Grilli is out.
