Pirates put closer Grilli on 15-day DL
APR 25, 2014 7:03p ET
The move was retroactive to April 21.
The Pirates called up right-hander Jared Hughes before Friday night's game against St. Louis. Set-up reliever Mark Melancon is expected to move into Grilli's spot and close.
Grilli, an All-Star last season, has already blown three of seven save chances this season and has a 4.50 ERA.
Melancon has allowed two runs in 11 innings this season. Left-hander Tony Watson could also be used to close.
