HILTON HEAD ISLAND, S.C. — Early on, Satoshi Kodaira was thinking only of playing well enough Sunday to make it to next week’s PGA Tour stop.

Those worries are over for Kodaira, a 28-year-old from Japan, who rallied from six shots behind to win the RBC Heritage in a playoff and gain an invitation to join the tour as a regular.

“This is a stage I’ve been dreaming about,” Kodaira said through an interpreter. “And having this opportunity to play full time is a dream come true. So of course I will accept full-time membership.”

Kodaira defeated Si Woo Kim on the third playoff hole, rolling in a 25-foot birdie on the par-3 17th hole, then punching his fist in celebration. It ended a drama-filled final round in which it appeared that Kim, Ian Poulter and Luke List had the lock on the title at different points.

But it was Kodaira’s relentless grind to the top that won the day. And with the game he showed, Kodaira appears like he’s got more big moments on tour ahead like countryman and five-time tour winner Hideki Matsuyama.

“I feel like I’m getting closer to that level,” said Kodaira, who is ranked 46th in the world and has played in 15 tour events. “I’d like to do my best in major championships and hopefully work hard at it.”

Bryson DeChambeau (66) and List (72) were tied for third. Third-round leader Poulter’s bid for a second tour title in three weeks ended with a 75 and a tie for seventh place.

LPGA: Brooke Henderson pulled away Saturday to win the Lotte Championship at Kapolei, Hawaii, for her sixth Tour victory.

Henderson, a 20-year-old Canadian, closed with a 3-under 69 for a four-stroke victory. She moved within two victories tying Sandra Post’s LPGA Tour record for Canadians.

EUROPEAN: Jon Rahm shot a 5-under 67 to win the Spanish Open at Madrid with the overnight leader, Paul Dunne, two strokes behind.

The fourth-ranked Rahm had six birdies in his final round to end the tournament on 20-under 268.

Rahm, a 23-year-old Spaniard, earned his third Tour win a week after finishing fourth at the Masters.

“When I made the decision to come straight from (the Masters) it wouldn’t be to just show up and walk around. I wanted to win this tournament,” Rahm said.
