The reads behind them

Form here is 60% of a player's last ten games and 40% of the season, weighed against what the books are charging once the vig is stripped out, and against what the matchup says. A prop only appears when the matchup backs it as well as the form does.

Angle 1

Rafael Devers Over 0.5 Home Runs

San Francisco Giants @ Atlanta Braves · first pitch 6:05 PM ET

+350at theScore Bet

Rafael Devers has gone over 0.5 home runs in 20% of 137 games this season and 40% across the last ten. He faces Bryce Elder.

Devers barrels the ball at the 78th percentile of qualified regulars.
Bryce Elder has allowed a home run on 3.63% 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 96th percentile on.

The case against

The price is not the problem here. The form read still has to hold at +350.

The last ten (40%) sits a long way from the season rate (20%), so this leans on a streak continuing rather than on a settled level.

What this is, and what it is not
