PHOENIX (Interstat) — In a stunning late-inning collapse Tuesday night, the Los Angeles Dodgers saw a four-run lead evaporate over the final three frames, culminating in a walk-off 5-4 victory for the Arizona Diamondbacks at Chase Field.

A crowd of 42,882 watched as the Diamondbacks, held scoreless for six innings by Dodgers starter Shohei Ohtani, mounted a furious comeback. They plated three runs in the seventh inning to get back into the game and completed the rally with two runs in the bottom of the ninth against Dodgers reliever Tanner Scott, who took the loss.

The defeat dropped the Dodgers to 88-69 on the season, while the Diamondbacks improved to 80-77. The result defied the pregame projections from Interstat, which had favored the Dodgers with a 53.6 percent probability to win and projected a high-scoring affair with Arizona winning 7-6.

For much of the game, it was Ohtani’s brilliance that defined the contest. The two-way star was dominant on the mound, pitching six shutout innings while allowing just five hits and striking out eight. He efficiently navigated the Diamondbacks’ lineup, at one point retiring seven consecutive batters and inducing a key double play in the fifth inning to escape a minor jam.

The Dodgers’ offense provided Ohtani with an early cushion. In the top of the second inning, Teoscar Hernández launched a solo home run, his 25th of the season, deep to left-center field off Arizona starter Brandon Pfaadt to give Los Angeles a 1-0 lead.

The game remained a tight, 1-0 pitchers’ duel until the sixth inning. Ohtani sparked the rally himself by drawing a leadoff walk. After a Mookie Betts popout, Freddie Freeman also worked a walk. With two outs, Hernández came through again, this time drilling a line-drive triple to center field that scored both Ohtani and Freeman, extending the Dodgers’ advantage to 3-0.

An insurance run was added in the top of the seventh when backup catcher Ben Rortvedt connected for his first home run of the season, a solo shot to right-center field that made it 4-0 and seemed to put the game out of reach.

However, the momentum shifted violently in the bottom of the seventh after Ohtani departed. Reliever Alex Vesia recorded the first out, but then allowed a sharp single to Ildemaro Vargas. Vesia struck out pinch-hitter Tim Tawa for the second out, bringing catcher James McCann to the plate. McCann delivered a double to center field, scoring Vargas and putting Arizona on the board.

The pivotal moment came next. Diamondbacks manager Torey Lovullo sent Adrian Del Castillo to the plate as a pinch-hitter. Del Castillo connected on a towering two-run home run to right field, scoring McCann and suddenly slicing the Dodgers’ lead to a precarious 4-3. The blast electrified the home crowd and completely altered the complexion of the game.

The Dodgers’ bullpen managed to escape the eighth inning despite issuing two walks, keeping the one-run lead intact. But in the ninth, Tanner Scott could not find the strike zone or record the necessary outs. He hit Vargas with a pitch to start the inning and then walked Tawa, putting the winning run on base with no outs.

McCann then executed a perfect sacrifice bunt, advancing both runners into scoring position. The Dodgers brought their outfield in, and the strategy initially worked as Jorge Barrosa hit a fly ball to medium-depth left field. While Alex Call made the catch, Vargas tagged and scored easily to tie the game 4-4.

With Tawa now representing the winning run at second base, Geraldo Perdomo stepped in. On a 1-1 count, Perdomo lined a single into left field. Tawa raced around third and slid home safely ahead of Call’s throw, triggering a celebration on the field as the Diamondbacks completed the improbable comeback.

The win went to Arizona reliever Ryan Thompson, who pitched a scoreless top of the ninth inning. He improved to 3-2 on the season. Scott fell to 1-4 with the loss.

Despite the loss, the Dodgers’ offensive output was sparse, managing only five hits. Hernández was the standout, going 2 for 4 with the home run, triple and three RBIs. Rortvedt provided the other key hit with his solo homer.

For the Diamondbacks, who collected nine hits, the victory was a testament to timely hitting. Del Castillo’s pinch-hit homer was the game’s biggest swing, while Perdomo’s walk-off single capped the rally. Pfaadt turned in a quality start for Arizona, lasting six innings and allowing three runs on four hits while striking out four. The Diamondbacks’ bullpen combination of Brandyn Garcia, Thompson and Jalen Beeks was flawless, retiring all seven batters they faced over the final three innings to keep the door open for the comeback.

The two teams will continue their three-game series Wednesday night at Chase Field. The Dodgers will look to rebound and solidify their playoff positioning, while the Diamondbacks will aim to carry the momentum from their dramatic victory.
