Kealakehe’s Michelle Uyeda provided one of the few surprises in the first two rounds of the singles bracket of the Carlsmith Ball / HHSAA State Tennis Championships at Central Oahu Regional Park on Thursday.

Uyeda, who reached the quarterfinals last year before losing to eventual champion Taylor Lau of St. Francis, beat OIA champion Lisa Owen 6-2, 6-3 then took out Kohala’s Gabrielle Bartolome 6-0, 6-1.

A rematch with Lau is next for Uyeda at 8:30 a.m. on Friday. Lau began defense of her title with sweeps. No other seeded player lost.

No seeded players lost in boys singles, either, and two-time defending champion Kawika Lam of Punahou swept both his matches 6-0, 6-0. He will meet OIA champion Andre Ilagan of Farrington in the next round.

All of the seeds in boys doubles held up as well, ‘Iolani’s Jordan Azuma and Phuc Hyunh are the top seed and take on Kalani’s Rayden and Koby Murata.

The only upset in girls doubles came in the first round when Mililani’s Erin Jyo and Kaua Beamer took out sixth-seeded Marissa Hayashi and Jordan Melcher of Waiakea 6-2, 6-3.

Sarah Ikioka and Kylee Kato of Kamehameha-Maui are the top seed and didn’t drop a game in the first two rounds.
