Yainer Diaz's first two at-bats Tuesday illustrated the biggest impediment for the Houston Astros' catcher amid his frigid start. In both, Tigers right-hander Reese Olson got ahead in the count with fastballs in the zone and followed with off-speed pitches in the dirt.

Yainer Diaz had a run-scoring single in back-to-back innings, rookie Ryan Gusto matched a season high with six strikeouts and the Houston Astros beat the Detroit Tigers 6-4.

Yainer Diaz produced a go-ahead, two-run single in the sixth inning, and the Houston Astros tacked on three runs an inning later to rally past the visiting Detroit Tigers 6-4 on Tuesday.
