Astros vs Tigers Preview, Parlay Picks

Houston Astros +1.5

I love this spot on the road for Houston tonight. The Astros struggled over the weekend, losing two of three games to the Baltimore Orioles. Houston was shut out in two of those three games.

Tonight, the Astros will send Spencer Arrighetti to the mound. Arithetti has struggled this season, with an ERA of 6.38 in a small sample size. I expect the right-hander to bounce back to form tonight against this Tigers lineup.

Jack Flaherty will get the nod for the Tigers. The veteran has struggled lately, allowing ten runs over his last two starts.

Jose Altuve 1+ Hit

The former World Champion draws a favorable matchup tonight.

Altuve has five hits in thirteen at-bats against Flaherty.

The Astros' second baseman has at least one hit in eleven of his fifteen games in August.
