For the second straight night, the Nationals reported to the ballpark for work only to go home without taking the field because of rain. After Thursday’s series finale against the Orioles was postponed and rescheduled for June 8, the Nationals’ series opener against the Phillies on Friday also was postponed. The game will be made up Sunday at 7:05 p.m. as part of a split doubleheader. The first of the two games is slated for 1:35 p.m.

Besides the all-star break, consecutive days without games are rare — and usually nonexistent — for teams over the course of a 162-game baseball season. Is it not part of the grind. It is unusual and not exactly welcomed.

“There’s nothing you can do about it,” Nationals Manager Dusty Baker said. “But you hate just to turn it on and turn it off and turn it on and turn it off.”

The Nationals skipped A.J. Cole in the rotation following Thursday’s postponement, but will just push back their rotation this time around. Tanner Roark, Friday’s scheduled starter, will start Saturday. Gio Gonzalez will start Sunday’s first game, and Max Scherzer will take the hill for the second.

Cole was optioned to Syracuse on Friday — along with left-hander Matt Grace — to make room on the roster for Shawn Kelley and Koda Glover, who were reinstated from the disabled list. Cole’s departure means the Nationals eventually will need another pitcher to fill the fifth starter’s spot. Baker wouldn’t say who would assume the role, though Jacob Turner is an obvious candidate.

Off the field, Friday was Trea Turner bobblehead day and the club announced the bobbleheads will be distributed to the first 25,000 fans entering the ballpark for the second game Sunday.
