Vietnam’s Nguyen Hung Anh stuns third seed at Kuala Lumpur Open

Nguyen Hung Anh turned the Panas Kuala Lumpur Open into a warning shot for the rest of the men’s singles draw, knocking out third seed Tama Shimabukuro 11-7, 5-11, 11-9 after already surviving three qualifying matches. For a player listed by Pickleball.com as an amateur from Vietnam, it was the kind of breakthrough that can change a profile overnight. For the bracket, it was another crack in the seed order on a day that already saw three of the top four seeds fall early.

The win carried extra weight because Shimabukuro arrived in Malaysia with real momentum of his own. The 15-year-old Japanese standout had just reached the men’s singles final at the Veolia Atlanta Pickleball Championships as the No. 22 seed, beating several higher-ranked opponents on that run. In Kuala Lumpur, though, Hung Anh absorbed the middle-game swing, reset in the decider and closed out one of the event’s most eye-catching results on May 15.

That is why the result matters beyond one scoreline. Southeast Asian men’s pickleball looked more volatile in Kuala Lumpur than it has in past stopovers, and Hung Anh’s run showed how quickly a qualifier can move from surviving the opening rounds to dictating the shape of the draw. A Vietnamese profile published this year identified Nguyn Hùng Anh as being born in 2004 and one of the country’s rising names, and this was the sort of win that gives that label real substance. Vietnam has been pushing harder into the regional scene, and this was a proof point against an internationally recognized seed.

The turbulence was not limited to Hung Anh and Shimabukuro. Jimmy Liong beat Syed Uzair Sufi 11-3, 12-10 in an all-Malaysian clash, feeding local hopes with a home-soil result that had to be earned in straight sets and a tight second game. Nasa Hatakeyama’s comeback over Hong Kit Wong added to the sense that the opening days were less about ranking position than about who could handle pressure in a live, shifting bracket.

That made the Kuala Lumpur Open, held May 13 to 17 at 9Pickle in Setia Alam, Shah Alam, feel like a better barometer of Asian depth than many early-round events. The tournament carried US$50,000 in prize money and 500 PPA points, and PPA Tour Asia had marked Kuala Lumpur as its second stop of the 2026 season after Hanoi, a reminder that this was part of a growing regional calendar, not a one-off showcase. Malaysia has already shown a taste for upsets, too: at the 2025 Panas Malaysia Cup in Kuala Lumpur, Tyson McGuffin and Eric Oncins stunned Ben Johns and Christian Alshon in the men’s doubles final. Hung Anh’s win fit that pattern, and it suggested the region’s seed sheet is becoming less of a script and more of a target.
