The Pittsburgh Pirates activated closer Jason Grilli from the disabled list before Tuesday night's game against the Milwaukee Brewers and he was available to pitch, the Pittsburgh Tribune-Review reported.
The right-hander was sidelined in late July with a strained forearm. At the time he was injured, Grilli had 30 saves and a 2.34 ERA in 42 1/3 innings this season.
Mark Melancon took over the Pirates' closer role while Grilli was out. Melancon is 2-1 with 10 saves this year.
"We'll use (Grilli) at least a couple times in non-leverage situations to see how he fares, how he feels," Pirates manager Clint Hurdle said. "We eventually plan on transitioning him back to the closer's role."
The Pirates entered Tuesday's game with a one-game lead over St. Louis in the National League Central.
