MLB Predictions for Thursday, August 13, 2026: WP Baseball Predictor's Best Bets and Top Matchups
Thursday's MLB slate brings nine games and plenty of opportunities for sharp bettors and fantasy players alike. At WP Baseball Predictor, our advanced sabermetric engine — powered by metrics including wOBA, FIP, DER, Pythagorean Win%, and pitcher xFIP — has processed today's matchups and surfaced some compelling picks. Here's a breakdown of the most interesting games on the August 13 card, along with our top WP picks and a few dark horse home run values you won't want to overlook.
Game of the Day: Seattle Mariners @ New York Yankees (1:35 PM ET)
The most lopsided probability on the board belongs to the Yankees, who our model projects at a commanding 62.0% win probability against the Mariners (38.0%). Logan Gilbert takes the mound for Seattle while Max Fried starts for New York, and the pitching matchup clearly plays into the model's confidence in the home side.
WP Pick: Yankees moneyline. A 62% win probability is one of the stronger edges you'll find on a nine-game slate. When our model pushes this far toward a moneyline favorite, the value is worth following straight up rather than hedging with a run line.
Dark Horse HR Alert: Luis García Jr. (Yankees)
With the Yankees generating significant offensive confidence in this projection, García Jr. represents an intriguing power upside value at a likely modest price in home run prop markets. Keep an eye on his spot in the lineup against Gilbert.
Fade the Chalk: Boston Red Sox @ Toronto Blue Jays (3:07 PM ET)
The single strongest win probability on today's entire slate belongs to the Boston Red Sox at 68.4%, making Toronto (31.6%) one of the bigger dogs of the day. Payton Tolle starts for Boston against a Blue Jays club sending out Max Scherzer, and despite Scherzer's reputation, our sabermetric model heavily favors the visitors.
WP Pick: Red Sox moneyline. A 68.4% implied win probability is the highest on the board today. Regardless of the name on the mound in Toronto, the underlying numbers point firmly toward Boston. This is the strongest single-game conviction play of the afternoon.
Dark Horse HR Alert: Wilyer Abreu (Red Sox)
In a game where Boston carries this level of offensive projection dominance, Abreu offers value as a dark horse home run play. If the Red Sox offense performs in line with model expectations, he's positioned as a sneaky power option at an attractive price.
Pitching Duel Worth Watching: Philadelphia Phillies @ Minnesota Twins (7:30 PM ET)
Thursday night's most intriguing pitching matchup features Aaron Nola squaring off against Taj Bradley in what shapes up as a competitive, low-margin affair. The Twins hold a slim 51.9% win probability to the Phillies' 48.1% — essentially a coin flip that our model barely tilts toward Minnesota.
WP Pick: Phillies +1.5. When the margin is this tight, taking the run line with the underdog is the sharper play. Philadelphia's offense, anchored by a lineup that includes Bryce Harper, gives the Phillies a real path to keeping this game close even if the Twins' home-field edge nudges the probability their way.
Dark Horse HR: Bryce Harper (Phillies)
Harper is listed as the Phillies' dark horse HR pick today, and in a near-even matchup where Philadelphia projects to stay competitive deep into the game, he represents outstanding value. In games where the run line is the play, power from your HR prop adds a complementary angle.
Value on the Run Line: Cleveland Guardians @ Detroit Tigers (1:10 PM ET)
The Tigers open the day slate as our model's 57.0% favorite over the visiting Guardians (43.0%), with Keider Montero starting for Detroit against Parker Messick. It's a meaningful edge for the home side, though not overwhelming enough to chase the moneyline aggressively.
WP Pick: Tigers +1.5. Detroit's 57% win probability combined with the run line cushion creates a strong risk-reward scenario. The Guardians remain dangerous, but the model's advantage sits clearly with the Tigers in this early afternoon matchup.
Late Night Spotlight: Milwaukee Brewers @ Los Angeles Dodgers (10:10 PM ET)
The nightcap features Shane Drohan against Roki Sasaki as the Dodgers hold a 52.1% win probability — a razor-thin edge over Milwaukee's 47.9%. This is essentially a pick'em, which makes the run line the play.
WP Pick: Brewers +1.5. In near-coin-flip games, our model recommends the run line cushion with the underdog. Gary Sánchez is flagged as Milwaukee's dark horse HR value today — a powerful hitter who can change a close game in a single swing.
