Moanalua continued its Oahu Interscholastic Association golf domination Thursday. The individual championships provided all the drama.

Mililani freshman Mari Nishiura provided the biggest surprise at Turtle Bay’s Fazio Course. She fired an even-par 72 to capture the girls title by four shots over three-time champ Eimi Koga.

"This is pretty important to me," Nishiura said. "This is my first OIA championship. I wanted to make, I guess, like a statement."

Two years ago Koga, now a senior at Moanalua, also won the state championship. She will play for Washington in the fall.

Na Menehune junior John Oda, headed for UNLV in the fall of 2014, will defend his state title in two weeks. He needed a clutch 12-foot birdie putt on the final hole to defend his OIA championship.

Oda trailed Pearl City senior Colby Takushi by two going into the last day. They were tied after 17 holes. Oda’s only back-nine birdie gave him a bogey-free 3-under-par 69. His 7-under 137 score was one better than Takushi.

The only other golfers who finished under par were Oda’s teammates — junior Brent Grant (70—140) and freshmen Shawn Lu (70—140) and Kiyosuke Hara (69—142). Desmond Mello, another Menehune, closed with 68 to finish at even-par 144.

Those scores detail how Moanalua became the first OIA boys team in 32 years to win a state championship last year.

The Menehune boys led by 34 after the first round at Turtle Bay.

"This team really jelled, they really get along very well," said Moanalua coach Gordon Yuen. "I coach and I set them free and I calm them down."

Moanalua’s girls were tied with Mililani after the first round but pulled away Thursday when Koga (77—149), Elizabeth Shishido (75—156) and Randi Kim (79—165) all shot in the 70s.

Nishiura did what she could, taking control before the final round was half over. Starting on the back nine, she holed out from a bunker on the 16th, drained a 4-footer on the next hole and chipped in on the 18th to make the turn in 3 under.

That gave her all the cushion she would need over a struggling Koga, whose consolation was a heartfelt group hug from her teammates at the end.

"I was just trying to keep up with Eimi on the second nine and not get too nervous," Nishiura said. "It worked a little."

That Koga played at all remains something of a miracle. She was hit in the head by an errant ball on Halloween Day and needed brain surgery to stop the bleeding internally.

She was told she couldn’t go back to school until January or golf for six months. She was playing in a month and in contention by December.

"Eimi is a little disappointed," Yuen said. "She had a traumatic experience this year. It’s a bonus that she is here."

Oda boiled his tournament down to his final three shots, which were flawless. He blasted his drive on the final hole nearly 300 yards and had 100 yards to the pin, from the middle of the fairway. He hit his wedge pin-high right, stared down the putt like Tiger with his hands around the bill of his cap, then caught the inside of the lower lip and flashed a fist pump.

"You’re my hero," a teammate yelled.

"That putt wasn’t easy, it was really bouncy," said Oda, who has also won the last two state amateur titles. "I just trusted what I saw and it went in."

The top 25 girls and 33 boys advance to the David S. Ishii Foundation state championships at Ka‘anapali Royal. The girls play Tuesday and Wednesday and the boys May 7-8.
