💰 Guardians vs. Astros prediction & best bet
Astros ML (-142)
Let's look a bit closer at Arrighetti's metrics to justify laying -142 on the Astros tonight. Houston's starter ranks in the 79th percentile for pitching run value, 85th percentile for fastball run value, and 94th percentile for hard hit rate.
As a result, Arrighetti has a 7-2 record this season, with a career-best 2.57 ERA and a 1.22 WHIP. The Guardians' lineup has largely struggled, ranked in the bottom five for batting average (.229) in 2026.
Head to FanDuel for the best line on the Astros' moneyline at -142 odds.

🔥 Best Guardians vs. Astros player prop bet
Jeremy Pena Over 1.5 H+R+RBIs (-140)
One of the Astros' most productive hitters in their lineup during their win streak has been Jeremy Pena. He's recorded over 1.5 Hits+Runs+RBIs in three straight starts, logging two or more hits in all three outings.
Pena ranks in the 98th percentile in xBA (.304), 77th in xwOBA (.354), and is 83rd in baserunning value. He's top-10 percentile for sprint speed, while posting a 14.9% strikeout rate, putting Pena in the 84th percentile.
Cantillo has a 4.38 ERA in 2026, including a dismal -8 in pitching run value (11th percentile). He's going to struggle against a hot hitter like Pena, so head to bet365 to place a wager on Pena to go over 1.5 Hits+Runs+RBIs at -140 odds.
💣 Guardians vs. Astros home run prediction
Jose Altuve to hit a home run (+710)
Jose Altuve has been another reliable hitter in a surging Astros offense. The veteran 2B has gone yard in three of his last five starts, and now, he'll face Cantillo, who is giving up a 91.8 fastball velo (13th percentile) this year.
While some of Altuve's underlying metrics may look sub-par, he's 75th percentile for squared up rate (28.7), which improves hitting efficiency to manufacture quality hits. Altuve also hit a bomb on Friday night, arguably against a better pitcher.
This is the time to cash in on Altuve's home run prop, as he's settling into a rhythm at the plate while facing a struggling pitcher in Cantillo. Sprinkle a quarter unit (0.25) on Altuve to hit his 9th homer of the season tonight at a robust +710 odds on FanDuel.
