Belisle (calf) was placed on the 15-day disabled list Wednesday with a right calf strain.
Belisle left Tuesday's game with the ailment, and it apparently is serious enough to warrant a trip to the disabled list. The right-hander's presence will be sorely missed, as he's only allowed one earned run through six innings so far this season. The Nationals recalled left-hander Sammy Solis to fill his spot in the Washington bullpen.
