Kapolei’s Jacob Yamaguchi pulled off a big upset Saturday at the OIA championships at Leilehua.
In a back-and-forth struggle, Yamaguchi defeated Radford’s Christian Tavares 13-12 in the 138-pound semifinals.
Tavares is No. 7 in Hawaii Prep World’s pound-for-pound rankings.
At the Officials touranament in December, Tavares defeated Yamaguchi 9-3.
Now, Yamaguchi moves on to face Moanalua’s Noah Wusstig in the 138 final. Wusstig topped Leilehua’s Naikoa Simao in the other semifinal Saturday.
“It was super hard,” Yamaguchi said after the match. “He caught me with a nice single in the beggining, and I had lost to him before, so I was like, ‘Oh no, I don’t want it to be a match like before.’ ”
Yamaguchi took an 11-10 lead and then scored two points with a near fall for a 13-10 edge, but Tavares immediately scored on a reversal to make it 13-12 with just a few seconds left.
“I’m excited to go against Noah,” Yamaguchi said. “It should be a good one.”
