Final. These games have been played; every price is as published.
3 selections from 47 MLB total bases props that cleared our form and pricing filters on Sunday's slate. Each one shows the price, the book quoting it, the matchup behind it, and the reason it might be wrong.
Our graded record is 82-61-5 at +37.1% ROI since Sep 25, as of Oct 19. Every public pick since Sep 25, 2026, losers included.

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
Gabriel Moreno has gone over 1.5 total bases in 51% of 124 games this season and 50% across the last ten. He faces Will Warren.
The case against
The price is not the problem here. The form read still has to hold at +155.
Angle 2
Nolan Arenado has gone over 0.5 total bases in 63% of 145 games this season and 80% across the last ten. He faces Will Warren.
The case against
At -150 the price does this pick no favours, so it stands or falls on the form read.
Arenado hits the ball hard at only the 15th percentile of qualified regulars.
Angle 3
Junior Caminero has gone over 1.5 total bases in 48% of 154 games this season and 50% across the last ten. He faces Patrick Sandoval.
The case against
Nothing about +120 helps here. The form read has to be right for this one to pay.
Patrick Sandoval has allowed hard contact on 36.0% of balls in play, below the 42% league mark.
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.
