Sean Zerillo's Best Bet For Tuesday

Detroit Tigers Logo
Mets F5 ML (-140)
Caesars Sportsbook Logo

By Sean Zerillo

Nolan McLean looks great, posting a 128 Stuff+ mark across his six-pitch arsenal (every pitch has a Stuff+ mark over 100). He’s posted a 2.58 xERA, 2.70 xFIP, and 3.50 botERA in a limited sample, and I think he’ll continue to outperform his projections (3.95 to 4.57 FIP range).

New York’s bats are white hot, posting a 143 wRC+ in August behind a franchise-record 177 runs and 53 homers.

Meanwhile, the Tigers are in their weaker offensive split against a right-handed pitcher.

I project the Mets F5 ML at -166.

Grant Neiffer's Top Home Run Pick For Tuesday

Shea Langeliers Home Run (+360)
DraftKings  Logo

By Grant Neiffer

Shea Langeliers has slowed down in the last few games, but he's still hit 11 home runs in August and has been one of the best hitters in the league over the last month.

This ballpark is a downgrade, but the matchup is great against Miles Mikolas.

Mikolas has been crushed by the long ball this season, and while I prefer targeting lefties against him, he's been walloped by right-handed power hitters (1.38 HR/9).

I make the fair odds on this home run prop around +300.

Pick: Shea Langeliers Home Run (+360, DraftKings)

This MLB betting system, titled "Steam Unders with Low OU Support", is built on the premise that sharp money moving totals downward, paired with weak public support on the Under, creates an exploitable edge in the betting market.

The strategy focuses on regular season games from 2019 to 2025, where the closing total lands between 8 and 10 — sweet spots for scoring volatility.

It isolates games where the Over/Under line has dropped significantly from open to close, signaling smart money on the under. Yet, public sentiment heavily favors the Over, with only a small share of bets backing the Under.

This mismatch between money and ticket count indicates potential value, especially when the difference between the two figures is meaningful but not extreme.

To reduce noise, the system excludes games played in extreme heat or cold, only including those where temperatures range from mild to warm. It also requires both teams to have a recent record of games that hover around the total, suggesting no extreme streaks skewing expectations.

These filters ensure that neither team is riding unsustainable Over or Under trends.

Ultimately, this system looks for low-confidence unders that have been steamed down by sharp bettors, where public interest is light and the number still sits within a realistic scoring range. The result is a consistent edge, backed by a high sample size and strong return on investment.

Pick: Under 8.5 (-115, FanDuel)
