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

Kyle Schwarber Over 0.5 Home Runs

Philadelphia Phillies @ Washington Nationals · first pitch 6:45 PM ET

+303at DraftKings

Schwarber barrels the ball at the 99th percentile of qualified regulars.
He bats left-handed into a left-hander, a split he ranks in the 93rd percentile on.

The case against

Angle 2

Kazuma Okamoto Over 0.5 Home Runs

Detroit Tigers @ Toronto Blue Jays · first pitch 7:08 PM ET

+450at bet365

Kazuma Okamoto has gone over 0.5 home runs in 22% of 144 games this season and 50% across the last ten. He faces Drew Anderson.

Okamoto barrels the ball at the 92nd percentile of qualified regulars.
He bats right-handed into a right-hander, a split he ranks in the 89th percentile on.

The case against

+450 is not what makes this one risky. The form read is, and it still has to hold.

Drew Anderson has allowed a home run on 3.37% of the batters he has faced, below the league rate of 3.5%.

The last ten (50%) sits a long way from the season rate (22%), so this leans on a streak continuing rather than on a settled level.

Angle 3

Matt Olson Over 0.5 Home Runs

Atlanta Braves @ Chicago Cubs · first pitch 7:40 PM ET

+350at BetOnline

He bats left-handed into a right-hander, a split he ranks in the 96th percentile on.
Kevin Gausman carries a 4.60 ERA and a .259 average against over 166.1 innings.

The case against

Nothing about +350 helps here. The form read has to be right for this one to pay.

Kevin Gausman has allowed a home run on 3.40% of the batters he has faced, below the league rate of 3.5%.
