Call went 0-for-3 with a sacrifice fly in Wednesday's 6-1 loss to the Pirates.
The Nationals didn't get on the board until the ninth inning, when Call brought Dylan Crews home on a sacrifice fly to center field. Call started the season strongly with three multi-hit efforts in his first eight contests, but he's cooled off and has gone 1-for-14 with three walks in his past five games.
