Yainer Diaz and Mauricio Dubon recorded three-hit games and Christian Walker delivered a timely two-run single in the bottom of the sixth inning as the Houston Astros rode a balanced offensive attack to a 7-4 interleague victory over the visiting Washington Nationals on Tuesday.

The Astros capped another week of variance on Sunday by losing the finale of a four-game series against the Athletics 7-1, which sent Houston to its ninth loss in its last 10 home games.
