The Arizona Diamondbacks erased a three-run deficit and rolled past the New York Yankees 8-4 on Sunday, September 20, 2026, at Chase Field. Nolan Arenado provided the decisive blow with a grand slam that flipped the game on its head, while a five-man bullpen locked down New York for the final six-plus innings after starter Corbin Burnes struggled early. The comeback win moves Arizona into the win column in emphatic fashion, a victory that required every bit of the roster depth on hand.

Nolan Arenado Grand Slam Powers Diamondbacks Comeback

Arenado was the undisputed story of the night. Finishing 1-for-4 at the plate, he made his one hit count in the biggest possible way — a grand slam that accounted for four of Arizona's eight runs and served as the turning point of the entire game. Without that swing, the Diamondbacks are staring at a loss. With it, they're celebrating a four-run victory.

Geraldo Perdomo added two hits and two RBI to support the cause, giving Arizona a pair of bats in the middle of the order that delivered when it mattered. Lars Nootbaar, Ketel Marte, and Gabriel Moreno each went 2-for-3 or 2-for-4, keeping the lineup churning and ensuring New York's pitching staff had no easy outs from top to bottom.

Corbin Burnes Struggles, But Arizona Bullpen Shuts Yankees Down

Burnes was not sharp. The right-hander lasted just 2.2 innings, allowing four earned runs on five hits and two walks while striking out two. New York knocked him around early and built a 4-1 lead that had Chase Field quieter than it wanted to be. The Yankees were hitting the ball hard, and Burnes had no answer for it.

Then the bullpen took over, and the story changed entirely.

  • Ryne Nelson: 1.1 IP, 2 K, 0 ER, 0 H, 0 BB
  • Justin Martinez (W): 1.0 IP, 2 K, 0 ER, 0 H, 0 BB
  • Taylor Clarke: 1.0 IP, 1 K, 0 ER, 2 H, 0 BB
  • Brandyn Garcia: 1.0 IP, 1 K, 0 ER, 0 H, 0 BB
  • Jonathan Loáisiga: 2.0 IP, 0 K, 0 ER, 1 H, 0 BB

That is 6.1 innings of scoreless baseball from five relievers. Nelson and Martinez were dominant, combining for four strikeouts without allowing a single baserunner between them. Martinez earned the win. Loáisiga handled closing duties cleanly, retiring six of the final seven batters he faced across two innings.

Yankees Fall Apart After Will Warren's Early Exit

New York starter Will Warren gave Arizona fits early, striking out four while allowing four earned runs on six hits and three walks across 4.1 innings — a line that shows both his effectiveness and his inconsistency. The game unraveled for the Yankees when Brent Headrick entered and immediately surrendered two earned runs on one hit and a walk in just 0.2 innings. That handed Arizona the lead for good and earned Headrick the loss.

New York's offense had its moments. George Lombard Jr. went 2-for-4 with a home run and two RBI. Heliot Ramos and Spencer Jones each added a solo shot. But three solo home runs against a bullpen that was otherwise untouchable was never going to be enough.

What's Next for the Diamondbacks

Arizona picks up a quality regular-season win with less than two weeks remaining in the 2026 campaign. The Diamondbacks showed they can dig out of a hole and that their bullpen is capable of carrying a game when the starter falters. Those are the kinds of answers a team needs going into the final stretch of the regular season. The next game comes soon enough — for now, Chase Field got the result it wanted on Sunday night.
