Jason Grilli (forearm) threw a bullpen session Thursday. It's the first time he's thrown off a mound since landing on the DL with a strained right flexor tendon. There's no word on what the next step is for the closer, but Grilli will likely need a few more mound sessions before going out on a short rehab assignment. Barring a setback, he'll be activated in early September.

Jason Grilli (forearm) was scheduled to throw off the slope of the mound Tuesday. It came after a few successful sessions of catch. "[Grilli] is doing really well. Moving forward at a very good fashion," Pirates manager Clint Hurdle said. It's possible the closer could throw a bullpen session by the end of the week. The Pirates are hoping to get Grilli back early next month.

Jason Grilli (forearm) could be cleared for a bullpen session next week. Grilli has already resumed a throwing program and continues to make quality progress in his recovery from a strained right forearm. He remains on track to be activated from the disabled list in early September.

Jason Grilli (forearm) is scheduled to begin a throwing program this weekend. There's some belief that Grilli will be ready to return to the Pirates' bullpen by the end of August, but an early-September activation date seems much more likely. Mark Melancon will continue to fill in at closer for the Pirates, who currently boast the best record in MLB.

Doctors determined after examining Jason Grilli (forearm) Sunday that the reliever is "making quality progress." Grilli remains shut down from throwing, as he's still receiving treatment for the strained flexor muscle in his right forearm. The closer won't rejoin the Pirates' bullpen until late August, at the earliest.

Jason Grilli (forearm) has vowed to return this season. Grilli is expected to miss 4-8 weeks after he strained the flexor muscle in his right forearm last week. The good news is that the injury is muscular in nature and not related to a tendon. As of now, he is not a candidate for surgery. "I'm going to be ready before the season is out," said Grilli. "You can mark my word on that." Grilli is expected to rest for nine to 12 days before being re-evaluated. Mark Melancon will continue to handle the closer role in the interim.

Jason Grilli has been diagnosed with a strained right flexor tendon. The diagnosis came from Dr. James Andrews. Grilli does not need surgery and this time, but he's looking at an extended period of rest, as most need 4-8 weeks to recover from such an injury. He'll 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. It could have been worse, though. Mark Melancon will continue to close while Grilli is on the shelf.

Dejan Kovacevic of the Pittsburgh Tribune-Review reports that Jason Grilli didn't hear a pop before being forced to leave Monday's game with a forearm injury. Grilli felt general soreness in his forearm that peaked when he threw his final pitch of the night. It's probably a good sign, though more won't be known about Grilli's status until he's examined further. He's already been placed on the disabled list.

Pirates placed RHP Jason Grilli on the 15-day disabled list with a right forearm strain. Grilli was forced to exit Monday's game after he hurt his forearm on a pitch. He's reportedly headed back to Pittsburgh for tests, but it certainly had the look of a serious injury. Mark Melancon should fill the closer role for now and makes for a must-own in mixed fantasy leagues.
