Astros vs Guardians MLB Betting Preview

When I placed this wager last night, I didn’t even know who was pitching.

This is a Pure Weather Under.

Do you know how cold it’s going to be at Progressive Field on Monday? It’s projected to be 37 degrees at first pitch. It might get even colder in the later innings.

There’s some wind blowing in from left field, but the ball shouldn’t be going far in these conditions. For this game, BallParkPal projects a -26% run-scoring factor behind a -42% home-run factor.

Astros vs Guardians Pick, Betting Analysis

Cleveland’s offense is always the same. The Guardians are likely to continue being a league-average, contact-heavy lineup powered by Jose Ramirez.

However, I believe Houston’s offense is cooling off after a red-hot start. The Astros boast a 124 wRC+ on the season, but that mark is down to 106 over the past two weeks.

I also really like Cleveland’s bullpen and defense. Even if I can’t say the same for Houston, there’s enough in this matchup for me to bet the Under.

Pick: Under 7.5
