The Arizona Diamondbacks welcome the New York Yankees to Chase Field on Saturday, September 19, 2026, for a 8:10 PM ET first pitch. Brandon Pfaadt gets the ball for Arizona against Yankees right-hander Cam Schlittler in what shapes up as an intriguing late-regular-season matchup. With September baseball carrying real weight for both clubs, this is exactly the kind of game that can define how a roster finishes the year. Coverage is available on DBACKS.TV and Arizona Sports 98.7 FM locally.

Pitching Matchup: Pfaadt vs. Schlittler

Brandon Pfaadt draws the assignment for the D-backs, and his ability to command the strike zone and generate soft contact will be tested against a Yankees lineup that knows how to grind out at-bats. Pfaadt has been one of the cornerstones of Arizona's rotation, and Chase Field gives him a familiar environment to work in.

On the other side, Cam Schlittler makes the trip to the desert for New York. Schlittler is a younger arm working to carve out his place in a competitive Yankees pitching staff, and facing a lineup that Arizona is running out Saturday will be a genuine test of his stuff and composure.

Arizona Diamondbacks Starting Lineup

• 1. Lars Nootbaar — LF
• 2. Ketel Marte — 2B

• 4. Geraldo Perdomo — SS

• 7. Tim Tawa — 1B

• 9. Jordan Lawlar — CF

Keys to Watch for Arizona

Ketel Marte in the Middle of Everything

Batting second, Ketel Marte is the engine of this offense. If he gets on base and sets the table for Gabriel Moreno hitting third, Arizona's lineup can do real damage in a hurry. Marte's plate discipline and ability to make consistent hard contact make him the hitter to track all night.

Geraldo Perdomo Hitting Cleanup

Perdomo at cleanup is a lineup construction worth noting. The shortstop has developed into a more complete offensive player, and the D-backs are trusting him in a pivotal spot against a Yankees staff that does not give anything away easily. How Perdomo handles that responsibility will go a long way toward deciding this game.

Corbin Carroll Finding His Footing

Carroll bats fifth tonight in right field. Getting Carroll going in September matters for Arizona's overall offensive identity. He has the speed and bat to create chaos when he is locked in, and a matchup against a younger starter like Schlittler is an opportunity worth watching closely.

Pfaadt's Command Against a Disciplined Lineup

The Yankees do not expand the zone. Pfaadt will need to work both sides of the plate and keep his pitch count manageable early. If he can get deep into the game and limit walks, Arizona's bullpen gets a chance to close things out at home.

Prediction

This is a winnable game for Arizona at Chase Field. Pfaadt pitching at home against a Yankees arm still establishing himself at this level gives the D-backs the edge on paper. Expect a competitive, lower-scoring game decided in the middle innings. Diamondbacks 4, Yankees 2.
