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 2

Liam Hicks Under 0.5 Hits

+146at BetOnline

Liam Hicks has gone under 0.5 hits in 39% of 145 games this season and 60% across the last ten. He faces Foster Griffin.

Hicks hits the ball hard at only the 8th percentile of qualified regulars.
Foster Griffin has allowed hard contact on 37.0% of balls in play, below the 42% league mark.
He bats left-handed into a left-hander, a split he ranks in the 19th percentile on.

The case against

+146 is not what makes this one risky. The form read is, and it still has to hold.

The last ten (60%) sits a long way from the season rate (39%), so this leans on a streak continuing rather than on a settled level.
