WASHINGTON – Anthony Rendon doubled twice and drove in three runs, and the Washington Nationals opened a six-game homestand with a 6-5 victory over the Houston Astros on Tuesday night.

Ryan Zimmerman added two doubles and two RBIs as Washington snapped a four-game losing streak.

Tanner Roark (6-4) pitched five innings in winning his third straight start. Rafael Soriano worked the ninth for his 14th save.

Houston's Jose Altuve returned to the lineup, going 4 for 5 with two doubles and two RBIs. He was limited to one pinch-hitting appearance in the last three games after being hit on the right hand by a pitch.

Dallas Keuchel (8-4) came in 6-1 with a 1.33 ERA over his last seven starts, but struggled with his command.
