World number 12 Norrie, who beat defending Melbourne Park champion Rafa Nadal at the season-opening United Cup, eased through the opening set at the Australian Open warm-up event before Gasquet hit back.

The Frenchman had a walkover in Friday's semi-final and looked slightly fresher than Norrie, levelling the match before getting a decisive break for a 5-4 lead in the decider.

Gasquet then closed out the contest on serve to win his first trophy since 's-Hertogenbosch in 2018, disappointing home fans who had been hoping New Zealand-raised Norrie would come out on top.

"It's an amazing title for me, especially now at my age," Gasquet said in a news conference. "I really didn't think I would win again."

Gasquet, the oldest men's champion at the Auckland event, will take on fellow Frenchman Ugo Humbert first up at the Australian Open.

In Adelaide, world number 84 Kwon became the first lucky loser to win an ATP title since Marco Cecchinato in 2018 at Budapest.

Kwon clinically took the first set by winning the majority of his first-serve points before Bautista Agut claimed the second set with his brilliant second-serve performance.

Bautista Agut broke Kwon's serve for a 4-3 lead in the third set but the South Korean broke back immediately, pulling off a remarkable comeback in a fiery contest.

As the match went to a tiebreak, Kwon triumphed owing to his flawless second serve as the 25-year-old another title to his collection after winning in Nur-Sultan in 2021.
