Houston Astros vs San Diego Padres Prediction

I’m not excited to get involved in a game where neither team can string together wins. I’m looking at the over instead. Javier has yet to find his footing through 27.1 innings with a 6.59 ERA and 1.68 WHIP. Vasquez has been hittable at times, especially at Petco, where he has a 4.91 ERA and a .299 allowed batting average through 47.2 frames. Both lineups are capable of doing damage, and there are shaky arms on the bump. I expect offense on Sunday night. Give me the over.
