MLB Predictions for Monday, August 31, 2026: WP Baseball Predictor's Top Picks
Monday's MLB slate brings 12 games and plenty of betting opportunity as we head into the final stretch of the 2026 regular season. WP Baseball Predictor's sabermetric engine — powered by advanced metrics including wOBA, FIP, DER, Pythagorean Win%, and pitcher xFIP — has processed the full card and identified the sharpest plays of the day. Here's a breakdown of the most compelling matchups and where the model sees the clearest edges.
Top MLB Picks for August 31, 2026
New York Mets @ Tampa Bay Rays (6:40 PM ET) — Rays Moneyline
This is the most lopsided matchup on the board by win probability. WP Baseball Predictor gives the Tampa Bay Rays a commanding 70.0% win probability against the visiting New York Mets, making this one of the model's strongest moneyline recommendations of the day. Robert Stock takes the ball for New York against Tampa Bay's Ian Seymour, and the Rays' analytical advantages shine through across the board here. At 70-to-30 in Tampa Bay's favor, this game represents the highest confidence play on the entire Monday slate. The Rays moneyline is WP's clear top pick of the night.
Dark Horse HR Watch — Ryan Vilade (Rays): With the Rays projected as heavy favorites and their lineup expected to be active, Vilade presents an interesting power-upside value play against a pitcher the model doesn't project as a strong suppressor in this environment.
San Diego Padres @ Cincinnati Reds (6:40 PM ET) — Padres Moneyline
The San Diego Padres bring one of the day's stronger win probabilities to Cincinnati, with WP's model projecting a 61.4% chance of a Padres victory against the Reds' 38.6%. Michael King gets the start for San Diego opposite Brady Singer for Cincinnati. The model's confidence here is meaningful — anything above 60% represents a clear lean in WP's framework. The Padres moneyline is a well-supported play, and San Diego's offensive construction grades out favorably in this matchup.
Dark Horse HR Watch — Ty France (Padres): France is worth a dart throw here as a situational power value play. In a game where the Padres project as clear favorites, lineup leverage could work in his favor against Singer late in the contest.
San Francisco Giants @ Atlanta Braves (6:05 PM ET) — Braves Moneyline
The early evening kickoff features Anthony Molina taking the mound for San Francisco against Atlanta's Bryce Elder at Truist Park. WP's model gives the Braves a 63.1% win probability to the Giants' 36.9%, making the Braves moneyline a confident recommendation. Home-field advantage aligns with the model's lean here, and the win probability gap of over 26 percentage points is substantial. Atlanta is one of WP's better-value moneyline plays of the afternoon window.
Seattle Mariners @ Boston Red Sox (6:45 PM ET) — Red Sox Moneyline
George Kirby, one of the more well-known arms on today's slate, makes the trip to Boston to face Red Sox starter Payton Tolle. Despite Kirby's reputation, WP Baseball Predictor's sabermetric model sides firmly with Boston at 66.0% win probability, leaving the Mariners at just 34.0%. The model's output here is driven by contextual team-level metrics rather than individual reputation, and the numbers point clearly toward the Red Sox moneyline as a strong play. Boston at home with a 32-percentage-point edge in the model is not something to fade lightly.
Oakland Athletics @ Texas Rangers (8:05 PM ET) — Rangers Moneyline
Jacob deGrom takes the hill for Texas against Oakland's Gage Jump in one of the evening's more intriguing pitching storylines. WP's model projects the Rangers at 62.8% win probability against the Athletics' 37.2%. The Rangers moneyline is the call here, backed by a win probability gap that comfortably clears WP's confidence threshold. This is a prime-time game with a clear directional lean, making it one of the better late-slate value plays of the night.
Additional Plays Worth Monitoring
- New York Yankees @ Los Angeles Angels (9:38 PM ET): WP projects the Yankees at 60.0% — Yankees moneyline is in play for late-night bettors.
- Milwaukee Brewers @ Chicago Cubs (7:40 PM ET): Brewers project at 57.0%, but WP recommends the Cubs +1.5 as the value play — a smart run-line hedge in a competitive NL Central matchup.
- Detroit Tigers @ Minnesota Twins (7:40 PM ET): Nearly a coin flip at 50.5% Tigers vs. 49.5% Twins. WP leans Tigers +1.5 for the slight value cushion in a toss-up game.
- Baltimore Orioles @ Colorado Rockies and Philadelphia Phillies @ Arizona Diamondbacks: Both games are listed at 50/50 with TBD starters — WP will update picks as lineup and pitching news becomes available.
Monday's Best Dark Horse HR Picks
Beyond the game-level picks, WP Baseball Predictor flags Michael Harris II (Braves) and Luis Robert Jr. (Mets) as notable dark horse home run values on Monday's card. Harris gets a home date at Truist Park in a game where Atlanta's offense is expected to be active as 63.1% favorites. Robert, meanwhile, is a power bat capable of going deep even in games where his team is a significant underdog — and at 30.0% Mets win probability, any production from him would represent outlier value.
