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 3

Mookie Betts Over 1.5 Total Bases

Los Angeles Dodgers @ Miami Marlins · first pitch 7:11 PM ET

+133at BetRivers

Mookie Betts has gone over 1.5 total bases in 34% of 108 games this season and 70% across the last ten. He faces Ryan Gusto.

Ryan Gusto has allowed hard contact on 43.4% of balls in play, above the 42% league mark.
He bats right-handed into a right-hander, a split he ranks in the 81st percentile on.

The case against

Nothing about +133 helps here. The form read has to be right for this one to pay.

The last ten (70%) sits a long way from the season rate (34%), so this leans on a streak continuing rather than on a settled level.

What this is, and what it is not

These are our strongest market-specific props, chosen on the best combination of recent form, season baseline, the matchup itself, and the line actually available. The Lab's card is a separate five-pick slate selected across every market, and it is graded on the public record.

Where the record lives: the Lab's public record starts Sep 25, 2026, the card and the boosts together, with every pick and every loss on the results page. Each prop above is frozen with the exact price and book shown from the moment it was published. These angles are not on that graded record; the card and the boosts are.
