MLB Predictions for Monday, August 3, 2026: WP Baseball Predictor's Best Bets and Dark Horse Picks
Monday night brings eight MLB matchups to the diamond, and WP Baseball Predictor's advanced sabermetric engine — powered by wOBA, FIP, DER, Pythagorean Win%, and pitcher xFIP — has processed the data and identified tonight's strongest plays. From a lopsided Yankees showdown to a value run-line opportunity in Milwaukee, here's where the analytics point us on August 3, 2026.
Tonight's Top Matchups and WP Predictions
St. Louis Cardinals @ New York Yankees (7:05 PM ET)
This is the marquee value play of the evening. WP Baseball Predictor gives the Yankees a 73.4% win probability against the Cardinals, making the Yankees moneyline tonight's most confident selection on the board. Michael McGreevy takes the ball for St. Louis against New York's Cam Schlittler, and the overall roster and situational analytics tilt heavily toward the home side. With the Cardinals holding just a 26.6% chance of pulling off the upset, this is the kind of edge our model is built to surface. Back the Yankees with confidence.
Tampa Bay Rays @ Colorado Rockies (8:40 PM ET)
The second-strongest probability on tonight's slate belongs to the Tampa Bay Rays, who carry a 69.8% win probability against the host Colorado Rockies. Ian Seymour gets the start for Tampa Bay opposite Michael Lorenzen. Colorado checks in at just 30.2% to win, making the Rays moneyline a high-conviction pick backed firmly by our Pythagorean Win% and run-environment modeling. Coors Field is always a variable, but when the win probability gap is this wide, the analytics say trust the process.
Pittsburgh Pirates @ Milwaukee Brewers (7:40 PM ET)
This matchup offers one of the most intriguing run-line opportunities of the night. WP Baseball Predictor projects the Brewers as the more likely winner at 57.8% to the Pirates' 42.2%, but that gap isn't wide enough to confidently back Milwaukee outright at likely inflated prices. Instead, our model issues a Pirates +1.5 pick, identifying value on Pittsburgh to keep it within a run. Bubba Chandler starts for the Pirates against Brandon Sproat. When two evenly contested teams meet and the margin is projected to be narrow, the run line becomes the smarter angle — and that's exactly what the data supports here.
Toronto Blue Jays @ Houston Astros (8:10 PM ET)
Shane Bieber takes the mound for Toronto against Houston's Cristian Javier in what projects as a moderately favorable matchup for the home team. WP Baseball Predictor gives the Astros a 59.4% win probability compared to 40.6% for the Blue Jays, and the Astros moneyline is the play. It's not a blowout prediction, but consistent edges in the 55–65% probability range are exactly where disciplined bettors build long-term value. Houston at home, with a meaningful edge in our model, is worth the action.
San Diego Padres @ Arizona Diamondbacks (9:40 PM ET)
Closing out the West Coast slate, Michael King starts for San Diego against Arizona's Brandon Pfaadt in a game where the Padres hold a 53.2% win probability — a slim edge. That narrow gap is exactly why WP Baseball Predictor issues a Diamondbacks +1.5 rather than a Padres moneyline. Arizona sits at 46.8%, close enough that the run line offers superior value to backing San Diego outright. When margins are this tight, taking the points is the disciplined, analytics-backed approach.
Tonight's Dark Horse Home Run Picks
Our model also identifies under-the-radar HR value plays — hitters whose matchup conditions and profile make them worth targeting in home run prop markets.
- Victor Mesa Jr. (Tampa Bay Rays) — With the Rays holding a commanding 69.8% win probability and the offense expected to produce against Colorado's pitching, Mesa Jr. presents a sneaky HR value play in what could be a high-scoring environment for Tampa Bay.
- Amed Rosario (New York Yankees) — In a game where the Yankees are projected to win nearly three out of four times, Yankees hitters across the lineup carry elevated value. Rosario, often overlooked in prop markets, is a dark horse worth targeting given the favorable matchup conditions.
Games to Monitor: TBD Starters
Three games — Nationals vs. Phillies, Dodgers vs. Cubs, and Giants vs. Rangers — currently show 50/50 win probabilities due to at least one TBD starting pitcher. WP Baseball Predictor does not issue picks without sufficient pitching data, and all three games remain no-play recommendations until lineups are confirmed.
