Reserving a place on the most prestigious trophy in Hawaii amateur golf was a matter of payback for Brent Grant.

Not against an opponent, but rather to a family that provided the foundation for his progression in the game.

“I can’t do enough to repay what my mom and dad have done for me,” Grant said. “When I win … it’s kind of a return on an investment, but that investment will never be fully repaid … as far as the time, the effort, all of it. I am here because of the people around me.”

With his parents, Jim and MartyAnn, following him around Oahu Country Club, Grant wrapped up a pre-Father’s Day present by capturing the 108th Manoa Cup with a 5-and-4 win over Maui’s Justin Ngan in Saturday’s 36-hole final.

Grant’s victory in the six-day test of physical and mental endurance on a soggy track in Nuuanu Valley added to a celebratory spring in which he won the individual title at the Pacific West Conference championship as a BYU-Hawaii freshman and was named the conference’s Player of the Year.

Grant fired a 1-under-par 70 in the qualifying round on Monday and trailed for just six of the 104 holes he played over the next five days on his way to becoming the second straight Moanalua graduate to win the state amateur match-play championship.

Grant closed out Saturday’s win with a 3-foot par putt on No. 14, the same green where fellow Na Menehune alum Tyler Ota clinched last year’s title.

Ota returned to help Grant into the green jacket awarded to the winner, then had a hand in flinging him into the OCC pool, along with past champions Brandan Kop and Jared Sawada and Jim Grant, Brent’s father.

Jim Grant returned from a six-month deployment in the western Pacific aboard the USS Charlotte just about a month ago and tracked Brent’s march through the 64-player bracket, culminating with Saturday’s win.

“We had good feeling all week and I was trying to hold back the excitement,” Jim Grant said. “Now that it’s over with and now that he’s pulled it off, it totally hasn’t sunk in yet, but it’s an incredible honor, incredible to just be part of it. It kind of transcends Father’s Day. He’s been fighting for this for four years now.”

After falling short in the quarterfinals the previous two years, including a loss to Ota last summer, the often excitable Grant powered through the bracket this time around while maintaining a brisk pace throughout.

“When he hits a good shot, you can see that he has a lot of energy,” said Annika Espino, a recent La Pietra graduate who caddied for Grant this week. “That’s actually really good for him, because it’s not anger, it’s more momentum than anything. That just drives him to hit better shots and make more putts. So I kind of like it when he just screams at himself. It’s kind of funny.”

Grant rose to No. 12 in the Division II rankings this spring while helping BYUH qualify for the NCAA championships. He started his roll after BYUH head coach Bob Owan and assistant Ryan Acosta tamed his tempo on the greens.

“They told me to stay patient and really focus on trying to get the speed right,” Grant said. “Once I got that down I ended up winning two tournaments back to back. I kind of figured it out and my putting has been pretty consistent.”

Ngan (pronounced Yen), an incoming senior at Baldwin, was looking to become the tournament’s youngest winner since 2002 at age 17, and the first from Maui since 2001. He earned medalist honors on Monday and went the distance in two matches on his way to the final.

“It gave me a lot more confidence in myself and in my game,” Ngan said. “Hopefully I can come back next year and get to the finals again.”

Grant moved ahead midway through Saturday’s morning round with a birdie on the par-3 ninth. He then landed his tee shot 10 feet from the pin on the par-4 10th. Ngan bogeyed and conceded the eagle to Grant.

Grant was 4 up after the first 18 holes and won the first hole after the break. But Ngan claimed the next three holes, closing to 2 down with a par on the par-3 fourth.

But Grant answered with a birdie on the next hole and didn’t give Ngan many openings the rest of the way.

“It’s a relief. I’m sure any of the guys who’ve won this tournament will tell you the same thing,” Grant said. “It’s a long week. Six days, eight rounds of golf with no breaks really. It’s all about conserving your energy. It’s all about maintaining a good routine.”
