(WASHINGTON) -- The Pittsburgh Pirates have placed closer Jason Grilli on the 15-day disabled list. Grilli suffered discomfort in his right forearm while on the mound against the Nationals in the ninth inning on Monday. Grilli is 0-1 with a 2.34 ERA and has a National League-leading 30 saves.
"The biggest thing we've got to do is get Jason back to Pittsburgh and be seen by our doctors and get a more thorough evaluation," Pittsburgh general manager Neal Huntington said. "The initial read was he's going to be down at least seven to 10 days so the DL becomes a no-brainer at that point, but the rest is speculative and anything else at this point would be purely that." Pirates manager Clint Hurdle said Mark Melancon will take over as the closer while Grilli recovers. "I think it's going to be somewhat of a seamless transition. We can't replace Jason but we are going to move Mark to the closer spot," Hurdle said.
