Mariners vs Blue Jays Preview, Predictions, Props
[subheader sizedown=”true” center=”false” text=”Mariners Betting Preview: Big HR for Big Dumper?” logo1url=”https://static.sprtactn.co/teamlogos/mlb/100/sea.png” link1=”https://www.actionnetwork.com/mlb/odds/seattle-mariners” link1follow=”false”][/subheader]
In an exciting matchup between the Mariners and Blue Jays, our PRO Projections indicate a strong potential for home runs in the second game of their series.
With Logan Gilbert facing off against Jose Berrios, the game’s total isn’t astronomically high, but there are hitters that our data favors for clearing the fences, offering potential value for bettors on Saturday.
One standout from the Mariners is Cal Raleigh. As their leading slugger and a switch-hitter, Raleigh’s admittedly offered at a short price of +375 to go yard today.
However, the price isn’t short enough — our PRO Projections model anticipates Raleigh crushing 0.33 homers.
Raleigh is excelling in barreling pitches, ranking in the 100th percentile, according to Statcast, and he’s already hit eight home runs this season.
Given that Berrios has allowed multiple home runs in half of his starts, Raleigh’s odds may be more appealing than they seem.
Pick: Cal Raleigh Home Run (+375; bet365)
[subheader sizedown=”true” center=”false” text=”Blue Jays Betting Preview: Big Value on Vlad” logo1url=”https://static.sprtactn.co/teamlogos/mlb/100/tor.png” link1=”https://www.actionnetwork.com/mlb/odds/toronto-blue-jays” link1follow=“false”][/subheader]
From the Blue Jays, Vladimir Guerrero Jr. is another player to watch.
After a slow start, the newly-signed cornerstone is finally picking up momentum, with two homers in recent games.
At +575 odds at BetMGM, this is a great bet — Guerrero is projected by PRO Projections to have a 22% chance of hitting a home run.
Pick: Vladimir Guerrero Jr. Home Run (+575; BetMGM)
