MLB Predictions for Thursday, August 20, 2026: Best Bets, Run Line Value & Dark Horse Home Runs
Thursday's MLB slate features nine games spread across the afternoon and evening, and WP Baseball Predictor's advanced sabermetric engine — powered by metrics including wOBA, FIP, DER, Pythagorean Win%, and pitcher xFIP — has processed every matchup to surface today's strongest picks. From a lopsided pitching duel in Tampa Bay to a high-value run line opportunity in Texas, here is everything you need to know before first pitch.
Top Game Previews & WP Picks for August 20, 2026
St. Louis Cardinals @ Cincinnati Reds — 12:40 PM ET
SP Matchup: Michael McGreevy vs. Brady Singer
The early afternoon game in Cincinnati is one of the day's most compelling matchups, and WP's model lands firmly on the Cardinals moneyline. With St. Louis holding a 62.2% win probability against Cincinnati's 37.8%, this is among the strongest moneyline edges on the board today. McGreevy draws the start for St. Louis against Brady Singer, and the Cardinals' overall analytical profile — built through wOBA-driven offensive efficiency and Pythagorean Win% indicators — gives them a decisive advantage in this one. This is a confident play for bettors looking for early-window value.
- WP Pick: Cardinals moneyline
- Dark Horse HR — Cardinals: Joshua Báez. As an under-the-radar bat in the St. Louis lineup, Báez represents the type of undervalued slugger WP's model frequently identifies through batted-ball and wOBA data. He's worth a flier in HR prop markets.
Toronto Blue Jays @ Tampa Bay Rays — 1:10 PM ET
SP Matchup: Shane Bieber vs. Ian Seymour
This is the most lopsided game on today's slate from a win probability standpoint. WP's model gives the Rays a 67.5% win probability against Toronto's 32.5%, making the Rays moneyline the day's highest-confidence selection. Shane Bieber takes the hill for the Blue Jays against Ian Seymour, but regardless of the individual pitching matchup, Tampa Bay's underlying metrics — including their DER and Pythagorean Win% profile — overwhelmingly favor the home side. If you're only playing one moneyline today, this is the one to circle.
- WP Pick: Rays moneyline
- Dark Horse HR — Rays: Ryan Vilade. Vilade is a prime dark horse target in a game where Tampa Bay's offense is projected to do damage. His matchup-based value makes him an intriguing prop play at what figures to be an inflated price.
New York Yankees @ Baltimore Orioles — 6:35 PM ET
SP Matchup: Gerrit Cole vs. Kyle Bradish
The marquee primetime matchup pits two AL heavyweights against each other in Baltimore, and WP's model sides with the road team. The Yankees moneyline comes in backed by a 61.3% win probability versus the Orioles' 38.7%. Gerrit Cole takes the mound for New York against Kyle Bradish, and while we won't project individual pitcher stats, the overall analytical fingerprint — wOBA, FIP, and team-level DER — tilts decisively toward the Yankees. This is an excellent moneyline play for evening bettors.
- WP Pick: Yankees moneyline
- Dark Horse HR — Yankees: Luis García Jr. García is the kind of analytically undervalued hitter WP's model consistently surfaces. In a game where New York is projected to control, look for García's HR odds to offer positive expected value.
Washington Nationals @ Texas Rangers — 8:05 PM ET
SP Matchup: Andrew Alvarez vs. Jacob deGrom
On paper, Jacob deGrom returning to the mound for Texas makes this look like a Rangers runaway. But WP's sabermetric model tells a different story: the Nationals hold a 56.6% win probability, making Washington the outright favorite. The WP pick here is Nationals +1.5, offering substantial run line insurance on a team the model believes is genuinely undervalued. This is today's premier contrarian play — a situation where analytics and public perception diverge sharply, creating real value.
- WP Pick: Nationals +1.5
- Dark Horse HR — Rangers: Justin Foscue. If the Rangers are going to push back, Foscue is the name to watch in HR props. He's a low-ownership option with meaningful upside in a high-profile evening game.
Los Angeles Angels @ Houston Astros — 8:10 PM ET
SP Matchup: Grayson Rodriguez vs. Peter Lambert
WP closes the night's card with a Astros moneyline pick backed by a commanding 64.0% win probability against the Angels' 36.0%. Houston's analytical profile remains one of the stronger in the American League, and their home-field advantage compounds that edge against a Los Angeles squad that the model rates significantly below .500 in this matchup. A strong play to close out Thursday's card.
- WP Pick: Astros moneyline
