The Washington Nationals placed closer Jonathan Papelbon on the 15-day disabled list Tuesday due to a right intercostal strain. The move was retroactive to Monday.
Right-hander Matt Belisle has been reinstated to the roster following a rehabilitation assignment.
It is the first time the 35-year-old Papelbon has been on the DL. He ranks 10th on the all-time saves list with 365. He ranks seventh in the National League this season with 16 saves.
