CINCINNATI (AP) - Jordan Zimmermann extended Washington's streak of dominant starts, and Danny Espinosa homered for the second straight game Saturday night, leading the Nationals to a 2-1 victory over the Cincinnati Reds.

The Nationals lost catcher Wilson Ramos, whose right leg buckled while he chased a passed ball in the seventh inning. He had to be helped from the field.

Zimmermann (2-3) gave up five hits and fanned nine. Washington's starters have allowed one earned run or fewer 19 times this season.

Espinosa hit a tiebreaking solo homer off Jose Arredondo (2-1).

Nationals rookie Bryce Harper was back in right field with a large bandage above his left eye, covering a 10-stitch gash from slamming his bat against a wall on Friday night.

He went 0 for 4 and struck out.
