Relentless collided with remarkable in a riveting final round of the LPGA Lotte Championship.

Relentless won.

Suzann Pettersen held off the remarkable Lizette Salas and her Saturday 62, winning an anti-climactic playoff at Ko Olina Golf Club.

Pettersen stared Salas down with eyes closed, shutting them while she putted in a return to how she played as a child.

"I have a lot better feel," Pettersen explained. "I don’t really try to steer the putt. I kind of visualize everything in my head. I visualize the line that I’ve read the ball, the speed. I’ve read it, and that’s it. And it’s kind of very ‘release and feel’ because I’m just letting it happen."

The no-look solution to her putting frustration, and a routine par in the playoff, were good for Pettersen’s 11th LPGA win. The 32-year-old Norwegian was good to the last putt, finishing four practically perfect rounds with a gutsy run as Salas erased a six-shot deficit.

Pettersen closed with a 5-under-par 67, making four back-nine birdies to keep up with the torrid Salas, who played the last 11 holes of regulation in 9 under.

Both finished at 19-under 269. Salas’ breathtaking Ko Olina course record included a rare back-nine 29.

But on the first playoff hole, the California girl who used to follow Mexican hero Lorena Ochoa with a "Vamos (Let’s go) Lorena!" sign, "chunked" her approach shot into the water.

Salas giggled, but torrid eventually turned to tears as the realization of what she had accomplished, and what she barely failed to accomplish, hit her in a rush of emotion.

"I played my butt off today," Salas told The Golf Channel moments after Pettersen’s winning two-putt. "After I eagled the 10th, I kept the momentum going. I haven’t shot 62 since I was 15. I’m very proud of myself. I was almost there for my first win, just so close … ."

So close that it hurt, again. Salas, a 23-year-old USC graduate, now has four top-10 finishes in her second year on tour. She has been in the top five going into the final round at her last four events.

She played in the last group at the first major, shooting 79 Sunday at the Kraft Nabisco while Inbee Park put her game into overdrive to win and become the No. 1 player in the world.

Salas went about making herself better with the help of her new friends — Ochoa and Nancy Lopez.

"I learned a lot about myself and Inbee and the type of player I want to become … ," she said Friday. "I learned how to really grind, and being here in Hawaii with the wind you really have to grind.

"I learned how to stay patient. I learned that a bad round doesn’t define who you are as a player."

Pettersen, who will move up to fifth in the world ranking, said flat-out Saturday that Salas will win.

"I birdied 15, and then I think I was aware that she was like 18 under," said Pettersen, now 5-for-7 in playoffs. "She wasn’t going anywhere, and I’m like, ‘Oh, my God, where did she start this day?’ because I didn’t remember seeing her next to my name on the list yesterday.

"She’s a tough cookie. She’s been playing fantastic. She’s just got to keep putting herself in this position, and she’ll get her win."

With Lotte’s $255,000 first prize, Pettersen has now won nearly $9.8 million and is seventh on the career money list. She has been ranked in the top 10 in the world for the past 306 weeks.

She had one bad swing this week at Ko Olina, through idyllic conditions the first and final days and gusty winds the middle two.

That came on the 13th Saturday, when a horn honked during her backswing. Pettersen hooked her drive, it hit the cart path and the ball disappeared.

It did not cost her the win.

"It was a truck," said Pettersen, who laughed after her one-putt bogey. "It felt like it was right on top of me. It was a little bit of an errant tee shot, a little bit unlucky for that to hit and bounce on the cart path, otherwise it would be in the rough and I would play the hole as a three-shot hole and maybe get a birdie at least or par.

"I really just tried to have a short memory there and just forget about it as quick as I could. I knew coming in I would have some shorter holes that I could attack, and every time I was on the green today inside 10 feet, I felt good with my putter. I made a lot of great putts coming down the stretch, and that’s a very nice feel."

Pettersen joined the LPGA in 2003 and didn’t win until 2007. It took time to tame her temper and allow her wisdom to catch up to her exceptional athleticism.

Her time has come. While 27 golfers fired rounds in the 60s on the final day, and Salas went from the sublime — knocking in an eagle at the 10th from 169 yards out — to the ridiculous with five straight back-nine birdies, Pettersen was imperturbable.

"You get older, you get smarter," she shrugged. "I’ve kind of figured out how I play well, and I play well when I stay aggressive. I hate to play defensive and I hate to play away from the pins, and obviously at times you have to. That’s when the experience comes in. But for me to shy away and not step on the pedal, that’s not me."

She survived a bogey on the final hole of regulation after Salas lipped out her 10-footer for birdie earlier. It was one of just three missed putts on the back nine.

First-round leader Ariya Jutanugarn put together a 66 to take third, four strokes back. I.K. Kim made a move with a final-round 65. It was only good enough to tie for fourth with Park, who finished with consecutive 67s.

That didn’t even get her close. Same for No. 4 Na Yeon Choi (66), defending champ Ai Miyazato (72) and Jessica Korda (69), who all finished eight shots back.

The terrific finish was yet another look at Pettersen’s brilliance, and a peek into Salas’ bright future.

"Too many positives from shooting a 79 at Kraft to shooting a 62 here in Hawaii," Salas said. "I can’t really describe the feeling. I just feel so proud of myself to put that 79 in the back of my mind and just to go out and play some golf."

What they played at Ko Olina on Saturday went far beyond that.
