Top Astros vs. Guardians predictions 

After 10,000 simulations of Guardians vs. Astros, the model is going Over 8.5 combined runs. For over/under betting, no team has hit the Over more than Houston this year, with Monday’s contest being the latest instance. The Over is 17-7 for the Astros and has hit in each of its last four games. The Over also sports a 6-3 record for Cleveland over its last nine.

Houston leads the AL in OPS while ranking dead last in ERA, so both teams often light up the scoreboard when the Astros are in action. Having Weiss on the mound won’t help with the latter as he’s given up 10 ER over his last 8.2 IP, but Houston is also projected to have the top two batters in terms of total bases accumulated. Both teams are forecasted to score over 4 runs, on average, as the Over has all of the value. Get the Astros vs. Guardians money-line pick at SportsLine.
