Bet Labs' Rockies vs Guardians Best Bet: System Suggests Under
By Bet Labs
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 in which the closing total lands between eight and 10 — sweet spots for scoring volatility. It isolates games where the over/under has dropped significantly from open to close, signaling smart money on the under, but in which public sentiment heavily favors the over as only a small share of bets are backing the under. This mismatch between money and ticket count indicates potential value, especially when the difference between those 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. The result is a consistent edge, backed by a high sample size and a strong return on investment.
Overall, this system has cashed 60% of its picks (533-359-46) and generated a 15% ROI. This season, the system is 115-71-8 (62%) and have produced an 18% ROI.
Pick: Under 8.5 (-115)

Nick Galaida's Cubs vs Brewers Best Bet: Fade Rea
By Nick Galaida
Tonight's Cubs game is as close to a "must-win" game as exists for a team on July 29.
The good news is they have a very rested bullpen after yesterday, so they shouldn't have to be unnecessarily aggressive with Colin Rea. This year, Rea has dramatic time-through-the-order (TTO) splits, with his batting average allowed jumping from .254 to .311 from his second to third TTO. He also has extremely negative splits with left-handed batters, which could be extra incentive to get him out of this game early as there are likely a pair of lefties likely in the top-four of Milwaukee's batting order. Chicago has a pair of southpaws — Drew Pomeranz and Caleb Thielbar — who could be summoned in that situation, especially if there are guys on base. It would be surprising to see Rea face more than 21 batters tonight.
Pick: Colin Rea Under 15.5 Outs (-110)

Charlie Wright's Braves vs Royals Best Bet: Back Kansas City Early
Erick Fedde is back in our lives! We successfully faded him last week in Colorado, where he was hammered for six earned runs over three innings. St. Louis cut ties afterward, and he ended up in Atlanta. Unless the Braves can magically fix Fedde, I'm going to keep attacking him.
Fedde gave up 26 earned runs over his final five starts with the Cardinals. After months of good BABIP luck, his ERA (5.22) is finally in line with his xFIP (5.27) and SIERA (5.42). Fedde ranks in the fifth percentile in xERA, the 12th percentile in average exit velocity and the third percentile in strikeout rate. If that wasn't enough, he also has a career-high 10.5% walk rate.
The Royals have picked things up at the plate recently, ranking 14th in OPS and 17th in wOBA against right-handed pitching in July — not spectacular, but an improvement from earlier in the season.
Tonight's projected lineup matches up well with Fedde as Kansas City's top hitters are all right-handed, outside of Vinnie Pasquantino. The Royals will likely round out their lineup with four lefties and Fedde has been pounded for a .290/.370/.495 slash line against lefties. He'll have to navigate the likes of Bobby Witt Jr., Maikel Garcia and Salvador Perez up top, then deal with a platoon disadvantage at the bottom.
Pick: Royals First 5 Innings Over 2.5 Team Total (-110)

Bet Labs' Nationals vs Astros Best Bet: Under Showing Value
By Bet Labs
The "Series Unders: Off Low-Scoring Games" system focuses on regular-season MLB matchups in which both teams are entering the second or later game of a series after producing minimal offense in their previous outing. When teams come off one- or two-game streaks of low scoring, particularly early to mid-series, the market can overcorrect or undervalue continued offensive stagnation.
This model anticipates that trend to persist and bets on the under when recent results and situational rhythm point to a slow-paced, low-output environment.
Overall, this system is 1391-1114-121 (56%) and has produced a 7% ROI. This season, that ROI has jumped to 18% as the system is 62-39-1 (61%).
Pick: Under 8.5 (-115)
