Athletics vs Astros Prediction

Both teams are tied 4-4 in their last 8 meetings and are 2-2 in their last 4 meetings in Houston.

In this Athletics vs Astros Prediction, the Astros are coming as -180 home favorites. The Astros are being overvalued in this spot as huge -180 home favorites, as they are 1-4 in their last 5 games and are putting Hayden Wesneski on the mound, with his 5+ ERA and 6.30 home ERA. On top of that, the Astros’ bullpen has been in bad shape and their offense has been ice-cold, averaging just 2.5 runs per game against righties in their last 5. I will take a stab with the A’s for plus money in this one.
