SAN DIEGO (AP)Brandon Nakashima earned his first ATP Tour victory in his hometown, beating friend and fellow Southern Californian Marcos Giron 6-4, 6-4 on Sunday in the San Diego Open final.

”It’s super-special, something you dream of, but to have it happen in my hometown with all my friends and family here, it’s a moment I’ll never forget,” said Nakashima, who had two previous finals appearances. ”I hope there are many more moments like this to come.”

Nakashima, a 21-year-old who grew up in San Diego and trained extensively at the event’s site as a junior, clinched the opening set in only 30 minutes. The second set, filled with lengthy rallies, took nearly an hour.

Giron, the No. 5 seed and former NCAA title winner from UCLA, wasn’t able to fend off Nakashima’s persistent ground strokes and well-placed serves. Nakashima had eight aces, six in the first set.

Serving at 5-4 in the second set, Nakashima tallied the match’s deciding two points when Giron pushed an easy volley into the net, followed by Nakashima’s second-serve ace.

He earned $93,090, about half of what received for reaching the third round of the U.S. Open in early September.

Nakashima, who was ranked No. 69 on the ATP Tour, moved up to 48, his highest ranking in nearly three years on tour. Despite the loss, Giron moved up to 53 from 58.

Not only was the singles title claimed by an American, the doubles title also taken by an American duo as the second-seeded pair of Nathaniel Lammons and Jackson Withrow defeated Australians Jason Kubler and Luke Saville 7-6 (5), 6-2.

The $612,00 event was held at Barnes Tennis Center, which next hosts the $757,900 WTA 500 San Diego Open, Oct. 8-16. That will feature 16 of the world’s top-ranked 20 women pros, led by No. 1 Iga Swiatek.
