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

Braden Montgomery Under 0.5 Total Bases

+110at theScore Bet

Braden Montgomery has gone under 0.5 total bases in 44% of 85 games this season and 80% across the last ten. He faces Troy Melton.

  • Troy Melton has allowed hard contact on 37.4% of balls in play, below the 42% league mark.
  • He bats left-handed into a right-hander, a split he ranks in the 31st percentile on.
  • Troy Melton carries a 2.52 ERA and a .216 average against over 110.2 innings.

The case against

The price is the weak part of this one, and the form read has to carry it at +110.

The last ten (80%) sits a long way from the season rate (44%), so this leans on a streak continuing rather than on a settled level.

+165at betPARX

Riley Greene has gone over 1.5 total bases in 47% of 133 games this season and 60% across the last ten. He faces Davis Martin.

The case against

+165 is not what makes this one risky. The form read is, and it still has to hold.
