Waldschmidt's Walk-Off Blast Erases Four-Run Cubs Lead

Arizona trailed 4-0 heading into the eighth inning and looked cooked — then Ryan Waldschmidt hit a 408-foot walk-off homer in the ninth to complete a stunning 5-4 comeback. The win probability swung from 9% to 100% on a single swing.

Clay Holmes was the best pitcher on the field and ended up on the losing side. The Cubs' starter went 7.0 innings, allowing just 2 hits, 0 earned runs, and striking out 5 — a performance that, on most nights, wins ballgames. Chicago built the cushion to match: Ian Happ put the Cubs up 3-0 in the fourth with a 397-foot homer to right that scored Seiya Suzuki and Michael Busch, then Busch added a run-scoring single in the sixth to push it to 4-0. Suzuki crossed the plate twice and Happ finished 1-for-4 with 3 RBI. Brandon Pfaadt, meanwhile, was getting hit — 6 hits and 4 earned runs over 6.2 innings — and Arizona's offense was nowhere to be found.

The eighth inning is where this game changed shape. Gabriel Moreno doubled to right, scoring Barrosa and moving Nootbaar to third. Then Geraldo Perdomo singled to center, scoring both Nootbaar and Moreno to make it a 4-3 game. Just like that, what looked like a comfortable Cubs win had a pulse. Dennis Santana came on and held Chicago scoreless over 1.1 innings, keeping Arizona within striking distance heading into the ninth.

What happened next was the kind of moment that defines a season. With Arizona's win probability sitting at just 9%, Waldschmidt — finishing the night 1-for-1 — launched a two-run homer 408 feet to left, scoring Fernandez and flipping the scoreboard to 5-4 Arizona. Win probability swung 91 points in a single at-bat, from 9% to 100%. Justin Martinez closed it out with a clean inning. The story of the night was a Cubs team that dominated for eight innings and a Diamondbacks team that refused to accept the outcome until the last possible moment. Holmes deserved better. Waldschmidt made sure he didn't get it.
