WASHINGTON - Jordan Zimmermann allowed six hits in eight innings, Bryce Harper singled home the ahead-run off R.A. Dickey and the Washington Nationals beat the Toronto Blue Jays 2-0 Tuesday in the opener of a day-night doubleheader.

A day after rain postponed the first meeting of the teams since 2012, Zimmermann (5-2) struck out four and walked one to win for the third time in four starts. After Toronto loaded the bases with one out in the seventh, he got Russell Martin to ground into a double play.

Drew Storen pitched a perfect ninth, earning his 17th save in 18 chances for the NL East leaders.

Harper's fifth-inning single gave him 29 RBIs in his last 27 games. Ryan Zimmerman added a sacrifice fly later in the inning.

In a game that began with only a few dozen fans in the stands, Dickey (2-6) gave up eight hits, struck out six and walked one.

Toronto had been the only major league team that had not been shut out. The Blue Jays have lost eight of their last nine road games.

Max Scherzer was to start the night game for the Nationals, and Marco Estrada for the Blue Jays.
