The Arizona Diamondbacks head to Nationals Park on Saturday, July 25, 2026, for a 4:05 PM ET matchup against the Washington Nationals. Left-hander Mitch Bratt gets the start for Arizona against Washington's Foster Griffin in what shapes up as a pitching duel between two arms still carving out their places in their respective rotations. For the D-backs, every road game at this point of the season is a chance to build on what they have established and tighten the screws heading into the second half stretch run.

Probable Starters: Mitch Bratt vs. Foster Griffin

Mitch Bratt draws the assignment for Arizona. The young left-hander has been working to establish consistency in his outings, and a road start in a major league environment like Nationals Park is exactly the kind of test that defines careers. For Bratt, command and sequencing will be essential — if he can keep Washington's lineup off-balance early, he gives the D-backs' offense time to settle in.

Foster Griffin takes the ball for the Nationals. Griffin is a veteran arm who has bounced between roles, and Washington will lean on him to keep Arizona's lineup in check. The D-backs cannot afford to let Griffin get comfortable — early pressure will be key.

Keys to Watch for the Diamondbacks

Corbin Carroll Sets the Table

Carroll leads off and his ability to get on base and create chaos on the basepaths is foundational to how this Arizona offense operates. A productive Carroll at the top of the order puts immediate pressure on Griffin and forces Washington's defense into uncomfortable situations from the first inning.

Ketel Marte in the Middle of the Order

Batting fourth, Marte remains the engine of this lineup. When Marte is locked in, the D-backs have a legitimate run-creator who can change the complexion of an inning. Getting him into the box with runners on will be critical against a crafty starter like Griffin.

Nolan Arenado Provides Veteran Presence

Arenado slots in at third base and bats sixth, adding a proven bat with postseason experience to the middle of this Arizona lineup. His ability to drive in runs in the middle innings could prove decisive in a tight, low-scoring game.

Bratt's Early Innings Will Tell the Story

Washington's top of the order — James Wood, Curtis Mead, and Andrés Chaparro — presents a real challenge. How Bratt navigates those first two turns through the lineup will largely determine whether Arizona's bullpen is asked to do heavy lifting or hold a lead.

Prediction

This is a winnable game for Arizona, and the lineup top to bottom has enough quality to put runs on the board against Griffin. The X-factor is Bratt. If he keeps Washington's young lineup from getting extended at-bats, the D-backs have the pieces to grind out a road win. Arizona 4, Washington 3.
