Brent Grant separated himself from a pack of likely golf suspects late in Sunday’s final round to win the 12th annual Turtle Bay Amateur.

Grant played his final 11 holes in 6 under par to shoot 69 at Turtle Bay’s Fazio Course. That and an opening round of 71 at the Palmer Course beat Kyle Suppa and Isaac Jaffurs by one shot. Kyosuke Hara, Shawn Lu and Nainoa Calip finished two back.

It was Grant’s second win in two months. He closed with a 68, then outlasted Dalen Yamauchi in a seven-hole playoff to capture the U.S. Army Hawaii Invitational in August.

Next summer, the 2014 Moanalua graduate will start his freshman year at Oregon State. He and Suppa, a Punahou junior who has verbally committed to USC, could see each other again in the Pac-12.

They have seen each other plenty at the top of local leaderboards.

Suppa won the State Stroke Play Championship this year, and has been an integral part of Punahou’s last two state high school championship teams. He teamed with Moanalua juniors Hara and Lu and Kamehameha’s Spencer Dunaway this summer to win Hawaii’s first Junior America’s Cup in 18 years.

Hara won at Turtle Bay last year. Lu, medalist at America’s Cup, was the first-round leader Saturday after a 68. Calip is the reigning Manoa Cup champ.

Jaffurs, a 26-year-old Kahuku graduate, tied his career low at his home course Sunday, shooting a tournament-best 5-under-par 67.

He had seven birdies and got up and down for par on the final hole (No. 9) — something Suppa and Grant could not accomplish. A bogey on the previous hole proved to be the difference for Jaffurs.

"If I could have just parred in I would have been fine," he said with a shrug. "I started feeling a little nervousness. Brent is a confident kid … those Moanalua boys."

Grant, somehow, found his swagger after a three-putt double-bogey on the 15th, which left him 3 over for the day.

"I hit a really good 9-iron out of the rough, really launched it, on the 16th," Grant recalled. "That’s when I felt my body start to pump a little bit. I pumped the next drive and really started to feel it. I almost drove the green on No. 18."

He birdied the 17th and 18th to make the turn in 37, lipped out for birdie on the next hole, drained a 25-foot birdie putt at No. 2 and drained another for eagle two holes later.

"The eagle was huge," Grant said. "It is rare that eagles happen."

Birdie on the next hole got him to 4 under and he hit it close at No. 7 to surge into the lead at 5 under, not that he knew it.

"I was getting back and forth from the guys I was playing with saying Kyle was 4 under," he recalled. "I thought I was totally out of it, but I re-checked my scorecard — as a player you don’t like to keep checking your card, but when I checked it on the last hole I realized I was 5 under and I needed a par to beat him by one."

Instead, both bogeyed the last hole. It was Suppa’s only bogey.

"I was trying to make birdie," Suppa said. "I hit to the back fringe and thought the putt was going to be slower than it was. I hit it pretty far past. I hit a good second putt (9 feet) but it didn’t break."

It was the only green he missed in regulation Sunday. The bogey dropped him into a share of second and left Grant — playing in the final group — two up heading to the final green.

Grant, who is working and going to KCC this semester, called Suppa "a great player who has been on the whole year. He’s a second-chance guy. If you give him one more chance on the golf course he is going to light it up."

Matthew Itagaki won B Flight, beating Dexter Chun on the first playoff hole after both finished at 157. Itagaki had a final-round 80 on the Palmer Course and Chun shot 74.

Last weekend, Robert Nakagawa (74—155) won A Flight and Chris Chung (77—171) took C Flight by six shots.
