I see significant value in backing the Nationals outright. Washington holds a clear starting pitching advantage with Foster Griffin on the mound.

Griffin has been a reliable innings-eater for the Nationals. Over his last 10 appearances, he owns a 3.38 ERA with a 1.01 WHIP across 58.2 innings. He limits opponents to a .210 batting average while generating 8.97 strikeouts per nine.

The other half of the MLB probable pitchers is Mitch Keller, who is struggling.

In his last 10 outings spanning 53.1 innings, he allowed a 6.41 ERA and a 1.50 WHIP. Opposing batters are hitting .280 against him during this rough stretch.

Pittsburgh being without Oneil Cruz and Spencer Horwitz puts a noticeable dent in their offensive production. The Pirates already lack elite slugging capabilities on the road. Missing two positional pieces forces them into a more conservative game plan prioritizing contact over power.

Washington is dealing with a staggering attrition rate within their rotation. Along with Gray, Irvin, and Williams, the Nationals are missing multiple bullpen arms. This decimation forces immense pressure on Griffin to pitch deep into the game to protect a heavily taxed relief corps.

The Nationals rank second in baseball with 5.38 runs per game at Nationals Park. Led by elite base-stealers like shortstop CJ Abrams, they rely on power and speed, swatting 1.33 home runs and stealing 1.00 bases per home contest.

Pittsburgh boasts a solid road offense, scoring 4.72 runs per game away from PNC Park. However, they lack Washington’s slugging capabilities. The Pirates fall behind in away OPS (.711) and away home runs per game (1.19).

For me, that tilts the pick to Washington.

Henry Davis UNDER 0.5 Hits (-117 at Caesars): Fading the Pirates catcher is heavily supported by recent data. Davis is currently riding a cold streak, failing to record a base hit in seven of his last 11 outings. He has also struggled against Washington pitching, failing to exceed 0.5 hits in two straight games against them.
