Matt Fitzpatrick‘s earliest memories of Harbour Town were as a spectator wondering if Tiger Woods would play the RBC Heritage.

Fitzpatrick defeated defending champion Jordan Spieth on the third playoff hole on Sunday, stuffing his approach in close on the par-4 18th to secure his first victory since the U.S. Open last June.

“I think I can retire now,” joked the 28-year-old Englishman, who uses a Harbour Town-style lighthouse headcover. “This is one I really wanted.”

Fitzpatrick hit 9-iron to within one foot on the closing lighthouse hole to set up the winning birdie.

Fitzpatrick had to sweat out a couple of prime chances by Spieth on the first two extra holes. Spieth raised his putter in triumph before watching his 12-foot birdie putt catch the right edge and spin out the first time the pair played the 18th. Then Spieth’s 9-foot birdie attempt ran out of steam on the right edge at the 17th hole.

“I felt every putt he hit was going to go in,” Fitzpatrick said.

Spieth still doesn’t understand how that first playoff putt didn’t drop.

“I think if I hit the same putt 10 times, it does in eight,” Spieth said. “It should go left at the very end there on the grain. It just wasn’t meant to be.”

There was no doubt about the final hole as Fitzpatrick, from 187 yards out, hit the front of the green and watched his ball settle next to the hole. Spieth’s attempt from 26 feet away rolled past and Fitzpatrick tapped in for the victory.
