Belisle (calf) will likely have his rehab assignment moved to Double-A Harrisburg, Chase Hughes of CSN Maryland reports.
Belisle began a rehab assignment Monday for High-A Potomac, and through three appearances, has allowed two earned runs over a total of four innings. The right-hander believes he is ready to return to the majors at any point, though the Nationals appear more inclined to take it slowly with his rehab.
