D-backs-Nats delayed by rain in 6th inning

WASHINGTON -- The Nationals and D-backs entered a rain delay in the top of the sixth inning Monday night with Arizona leading, 5-4.

Arizona took the lead with a five-run fourth inning, highlighted by a three-run homer from Yasmany Tomas, his 30th homer of the season, off Nationals right-hander Tanner Roark. Roark lasted just four innings, his shortest start since June 5, and surrendered five runs on four hits but struck out six.

Washington answered with three runs in the bottom of the fourth, including a two-run double by Trea Turner off right-hander Archie Bradley, who left the game after allowing four runs on six hits in 3 2/3 innings.
