Toronto Blue Jays vs. Washington Nationals Prediction – July 28, 2026
The Toronto Blue Jays make the trip to Washington to face the Nationals on July 28, 2026, and WP Baseball Predictor's model is pointing firmly toward the home side. With a projected win probability of 65.5% in favour of the Nationals against just 34.5% for Toronto, this qualifies as a strong-favourite designation — and the numbers behind that call are hard to argue with.
Starting Pitcher Matchup: Cavalli Holds a Clear Edge
The starting pitching matchup is the centerpiece of this analysis, and it tells a compelling story in Washington's favour.
Cade Cavalli (Washington Nationals)
Cade Cavalli takes the ball for the Nationals carrying an impressive xFIP of 3.18, a figure that signals he has been pitching to a genuinely elite level of underlying performance. xFIP strips away the noise of defence and sequencing to evaluate a pitcher on the quality of contact and strikeout-to-walk outcomes he controls. A 3.18 mark puts Cavalli among the better starters in the league and gives Washington a significant advantage before the lineup even steps in.
Shane Bieber (Toronto Blue Jays)
Shane Bieber counters for Toronto, but his xFIP of 5.03 paints a concerning picture. That number suggests Bieber has been vulnerable to hitters in terms of the underlying quality of at-bats he's allowing, and against a Nationals offence that is clicking, that could be a problem. The gap between Cavalli's 3.18 and Bieber's 5.03 is not a marginal difference — it is one of the more lopsided starting pitcher matchups you'll find on any given slate.
Why the WP Model Favours Washington
Beyond the pitching matchup, the broader team metrics reinforce the model's lean toward the Nationals. Washington's offence comes in with a team wOBA of 0.334, a strong indicator of overall offensive production. Toronto, by contrast, sits at a team wOBA of just 0.297, a meaningful gap that suggests the Nationals are generating significantly more offensive value per plate appearance.
On the pitching side, the Blue Jays actually hold the edge in team FIP (4.02 vs. Washington's 4.80) and team ERA (4.14 vs. 4.76), but those bullpen and rotation-wide numbers take a back seat when Bieber's individual xFIP disadvantage is this pronounced. The model weighs the starter matchup heavily, and Cavalli's dominance in that category is a primary driver of the 65.5% projection for Washington.
Injury Report: Key Absences to Watch
Both clubs are navigating notable injury situations heading into this contest.
- Blue Jays IL: Brandon Barriera (Undisclosed, 7-Day IL), Jonatan Clase (Foot, 10-Day IL), Patrick Corbin (Shoulder, 15-Day IL), Daniel Guerra (Elbow, 7-Day IL), and Yariel Rodriguez (Undisclosed, 7-Day IL) are all sidelined. The absence of multiple pitching options limits Toronto's depth should Bieber struggle early.
- Nationals IL: Connelly Early (Elbow, 15-Day IL), Seaver King (Oblique, 7-Day IL), Brad Lord (Side, 15-Day IL), Drew Millas (Finger, 10-Day IL), and PJ Poulin (Forearm, 15-Day IL) are unavailable. Washington's bullpen depth bears monitoring, though Cavalli's strong underlying numbers suggest he may not need heavy relief support.
Dark Horse Home Run Picks
Looking for value in the home run market? These two names are worth a look:
- Luis Urías (Blue Jays): Our dark horse pick on the Toronto side, Urías has the power to make Cavalli pay if he catches a pitch to his liking.
- CJ Abrams (Nationals): Abrams is the dark horse selection for Washington and offers sneaky upside against a Bieber who has been hittable based on his underlying metrics.
Final Prediction
With Cade Cavalli's elite xFIP of 3.18 against Shane Bieber's 5.03, a superior Nationals team wOBA, and the WP model projecting Washington at 65.5%, the Nationals moneyline is the play on July 28. Back the home side with confidence.
