๐ฐ Guardians vs. Red Sox prediction & best bet
Guardians ML (+115 via BetMGM)
Gray is having his best season in three years, but he hasn't been invincible.
The Red Sox right-hander has posted a 3.21 ERA since the All-Star break - compared to his 2.54 ERA pre-break - and has allowed three earned runs in each of his last two starts. With the Red Sox winning in just two of Gray's last four starts and the Guardians in a tight race in the AL Central, I don't agree that Cleveland should have just a 46.51% implied win probability.
Guardians ML (+115 via BetMGM) is the best line available among the top MLB betting sites.
Score prediction: Guardians 4, Red Sox 3
📡 SBR Edge: Winnin' Griffin
The Guardians are 22-8 in Griffin's starts this season.
๐ฅ Best Guardians vs. Red Sox player prop bet
Chase DeLauter Over 1.5 total bases (+180 via BetRivers)
Chase DeLauter has gone over this line in two of his last three games, going 5-for-12 with a home run and a double in that span.
This line is inflated because of how dominant Gray has been overall this season, but it ignores that he's been trending downward after the All-Star break. Gray also throws mostly fastballs to left-handed hitters - 52.2% of the time - and DeLauter is slugging .521 against that pitch type this season.
DeLauter Over 1.5 total bases (+180 via BetRivers) is the best line available among the top sports betting sites.

๐ฃ Guardians vs. Red Sox home run prediction
Jo Adell Over 0.5 home runs (+850 via BetRivers)
While Gray's 2.82 ERA on the season is impressive, he ranks in just the 55th percentile in barrel rate (7.2%), meaning he's not elite when it comes to limiting hard contact. Meanwhile, Jo Adell has already homered in just eight career at-bats against Gray.
The Guardians outfielder has a .460 expected slugging percentage against fastballs this season, and Gray throws fastballs 68.8% of the time to right-handed hitters. Adell Over 0.5 home runs (+850) is the best line available among the top sports betting apps.
