In an all-Spanish final group alongside David Puig, Rahm birdied the final two holes to tie Hidalgo at 14-under-par, forcing extra holes. Both players birdied the first playoff hole, but Rahm's missed chip on the second allowed Hidalgo to secure the win with a short two-foot putt.

"Just two or three years ago, I was standing in the trees, watching Jon play. To now be here winning the tournament is unbelievable. It's amazing," Hidalgo reflected.

This was the first time since 2019 that the national Open featured an all-Spanish final group. That year, Rahm had won comfortably, but this year’s showdown was much closer from the start.

Hidalgo’s two-shot lead was erased at the very first hole after he missed a three-foot putt for bogey, while Rahm and Puig both birdied, narrowing the gap. Hidalgo quickly responded with a birdie on the 2nd hole after a remarkable approach from a fairway bunker. Puig’s 15-foot birdie putt tied him with Rahm, who then dropped a shot on the 3rd.

Puig surged ahead with three birdies in the first four holes, while Hidalgo narrowly escaped with par. Rahm’s three-putt on the 4th left him trailing by two. Hidalgo then bogeyed the 5th and 6th holes, giving Puig a two-shot lead, which increased to three after a birdie on the par-five 7th.

At the same time, Jens Fahrbring climbed to 10-under after eagling the 7th, while Rahm dropped another shot. Puig stumbled with a bogey on the 8th, but both Hidalgo and Rahm birdied to close the gap. Hidalgo added another birdie on the 9th, moving to the turn tied for the lead, while Rahm followed with a birdie of his own, keeping him one shot behind. Puig, however, salvaged a par with an excellent recovery.

Rahm's birdie on the 10th brought all three players level, but Puig lost ground with a bogey on the 11th. Hidalgo took the outright lead on the 13th, as Puig bogeyed and Rahm double-bogeyed, dropping them both to 11-under.

Fahrbring, who had moved into second place with three consecutive birdies, bogeyed the 15th. Meanwhile, Hidalgo misfired on the 14th, sending his ball off line into a tree, but he recovered with an astonishing up-and-down after a towering flop shot. Rahm’s birdie brought him within one shot, and after another birdie on the final hole, Hidalgo’s missed putt sent the pair into a playoff.

In the playoff, Hidalgo found the front of the green on the driveable par-four, while Rahm chipped close. Both made birdie on the first extra hole. However, Rahm’s tee shot on the second playoff hole went towards the grandstand, and after he chipped through the green, Hidalgo took advantage, calmly sinking a two-foot putt for victory.

"I stayed relaxed all day, even after missing the short putt at the 1st and on the 72nd hole," Hidalgo said. "On the 8th tee, I thought David Puig might run away with it, but Jon and I held our ground despite some mistakes."

He also paid tribute to his supporters, including his caddie and best friend, and his family, who traveled to watch him play. "My grandpa would have turned 80 yesterday, and my family and friends have all been here for me. This win is for them."

Puig finished tied for 10th alongside Jens Fahrbring, Tommy Fleetwood, Joe Dean, Grant Forrest—who shot an impressive 64 on Sunday—and Sean Crocker. South Africa’s Jayden Schaper took sole possession of ninth place at 9-under, with Alfredo Garcia-Heredia, Patrick Reed, and Tyrrell Hatton sharing 10th.
