The reads behind them

Angle 2

Cal Raleigh Over 0.5 Home Runs

Athletics @ Seattle Mariners · first pitch 9:40 PM ET

+340at betPARX

Cal Raleigh has gone over 0.5 home runs in 17% of 105 games this season and 40% across the last ten. He faces Jack Perkins.

Jack Perkins has allowed a home run on 4.16% of the batters he has faced, above the league rate of 3.5%.
He bats left-handed into a right-hander, a split he ranks in the 83rd percentile on.

The case against

+340 is not what makes this one risky. The form read is, and it still has to hold.

The last ten (40%) sits a long way from the season rate (17%), so this leans on a streak continuing rather than on a settled level.
