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

Luis Garcia Jr. Under 1.5 Total Bases

Tampa Bay Rays @ New York Yankees · first pitch 8:00 PM ET

-155at BetMGM

Luis Garcia Jr. has gone under 1.5 total bases in 64% of 151 games this season and 90% across the last ten. He faces Nick Martinez.

Nick Martinez has allowed hard contact on 32.9% of balls in play, below the 42% league mark.
Nick Martinez carries a 3.10 ERA and a .249 average against over 180.0 innings.

The case against

The price is the weak part of this one, and the form read has to carry it at -155.

The last ten (90%) sits a long way from the season rate (64%), so this leans on a streak continuing rather than on a settled level.

Angle 2

Chandler Simpson Under 1.5 Total Bases

Tampa Bay Rays @ New York Yankees · first pitch 8:00 PM ET

-220at theScore Bet

The case against

At -220 the price does this pick no favours, so it stands or falls on the form read.

The last ten (80%) sits a long way from the season rate (60%), so this leans on a streak continuing rather than on a settled level.
