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, and these are separate from the card play above.

Angle 1

Oswald Peraza Under 0.5 Total Bases

+100at theScore Bet

Oswald Peraza has gone under 0.5 total bases in 50% of 101 games this season and 70% across the last ten. He faces Jared Jones.

  • Peraza hits the ball hard at only the 31st percentile of qualified regulars.
  • Jared Jones has allowed hard contact on 40.0% of balls in play, below the 42% league mark.
  • He bats right-handed into a right-hander, a split he ranks in the 9th percentile on.

The case against

The price is not the problem here. The form read still has to hold at +100.

Jared Jones carries a 4.83 ERA and a .236 average against over 72.2 innings.

The last ten (70%) sits a long way from the season rate (50%), so this leans on a streak continuing rather than on a settled level.

Angle 2

Esmerlyn Valdez Over 0.5 Home Runs

+650at Fanatics

Esmerlyn Valdez has gone over 0.5 home runs in 22% of 67 games this season and 20% across the last ten. He faces Ryan Johnson.

  • Valdez barrels the ball at the 99th percentile of qualified regulars.
  • Ryan Johnson has allowed a home run on 5.05% of the batters he has faced, above the league rate of 3.5%.
  • He bats right-handed into a right-hander, a split he ranks in the 77th percentile on.

The case against

+650 is not what makes this one risky. The form read is, and it still has to hold.
