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.

On Wednesday, the Houston Astros (15-13) are hosting the Detroit Tigers (18-11), at 2:10 p.m. ET, in the second game of a three-game series. The Astros (-118 on the moneyline) and the Tigers (-102) will meet in an expected close contest. The Astros will give the ball to Hayden Wesneski (1-2) versus the Tigers and Jackson Jobe (2-0).
