Nick Kyrgios rained down 23 aces as he beat David Goffin in a 4-6, 6-3, 7-5 comeback to win the Japan Open and claim his third title of the season on Sunday.
The Australian added the Japanese event - biggest of his career to date - to the first two trophies of his career, which he won earlier in 2016 in Marseille and Atlanta.
"It was a great week and I'll be here again," Kyrgios, who pronounced himself "genuinely humbled" with the victory, said. "I'm going to come here, for sure, for my whole career."
The winner quickly cleared out of Japan to reach the upcoming Shanghai Masters which began play as his final was in progress.
"Shanghai bound now and back to it all over again. No time to stop and savour anything," he tweeted.
Kyrgios spent two hours on court against his Belgian opponent, saving 11 of a dozen break points while breaking Goffin twice - including in the penultimate game which set up victory.
Kyrgios put his big game on display for eager Japanese fans, who adopted the 21-year-old as a favourite after the early elimination of national tennis hero Kei Nishikori.
Kyrgios put in a massive effort to start turning the momentum after dropping the first set to the fifth-seeded Goffin.
The 15th-ranked Australian saved five break points to hold for 2-1 in the second set and then broke in the next game on his way to levelling at a set each.
In the third, his break of Goffin for 6-5 made the different as he served out the win a game later.
Victory helped Kyrgios in the points chase to the season-ending finals next month in London, with the Australian moving to provisional 12th for the eight-man World Tour Finals.
Kyrgios now stands 38-14 for the season, becoming the fifth men's player to win three or more titles in 2016.
