WESTWEGO — Jon Rahm and Ryan Palmer got off on the right foot in the final round of the Zurich Classic on Sunday afternoon.

And they stayed a few steps ahead of the rest of the field the rest of the day, shooting a 3-under par 69 over the TPC of Louisiana course to finish three shots ahead of Sergio Garcia and Tommy Fleetwood.

Rahm/Palmer, who began the day tied for the lead with Scott Stallings and Trey Mullinax, finished at 26-under par 262 in their first-time participation as teammates in the event.

Rahm, No. 11 in the World Golf Ranking, and Palmer, ranked No. 70, each received $1,051,200 from the total prize money of $7.3 million. Rahm’s eighth top 10 finish of the season broke a tie with Rory McIllroy for the most on Tour.

“I got close this year a couple of times,” Rahm said. “For the most part, golf is an individual sport. You get to share that win with your caddie on the golf course and we’ve both been able to do that. But to share that win with a partner you’ve been playing with and know that we both played our best this week to be able to get it dome is something special.”

The teams of KH Lee/Matt Every and Brian Gay/Slovakia’s Rory Sabbatini finished tied for third at 21 under and four teams tied for fourth at 20-under — Seamus Power/David Hearn, Roberto Castro/Cameron Tringale, Kevin Kisner/Scott Brown and Hank Lebioda/Curtis Luck. Stallings/Mullinax tied for 13th after shooting a final-round 77 to finish at 18 under.

“What an awesome week,” Palmer said. “Our games complement each other so much — the way we drive the ball, our iron play, and there’s nothing better than missing greens knowing his short game is behind me.”

Rahm/Palmer started the day with a par and it proved to be significant as it gave them a lead they would never relinquish after Stallings/Mullinax bogeyed the same hole. A birdie by Rahm/Palmer on the second hole gave them a two-shot lead.

After a string of three pars, Rahm/Palmer had their first bogey of the day at No. 6, but still led by two strokes over Stallings/Mullin and Garcia/Fleetwood.

Garcia/Fleetwood birdied No. 7 to get within one shot, then bogeyed nine and birdied 11 to again get within a shot. Stallings/Millinax joined them at 22-under when they birdied No. 7.

A bogey at No. 13 dropped Gracia/Fleetwood out of the second-place tie moments before Rahm/Palmer moved to 24-under and a two-shot lead with a birdie at No. 10.

The lead grew to three strokes when Stallings/Mullinax bogeyed No. 11, dropping into a second-place tie with Garcia/Fleetwood and Gay/Sabbatini.

Garcia/Fleetwood took sole possession of second place with a birdie on No. 17, but moments later Rahm/Palmer birdied No. 13, then birdied 14 to take a four-shot lead.

“Our number all day was trying to get to 24, so 5-under today,” Garcia said. “But we realized it wasn’t that easy. The greens were really, really fast. They were very firm. They were difficult to handle.”

It was the fourth career PGA Tour victory for Palmer, who moved up to 19th in the FedExCup standings, and it was the third career Tour victory for Rahm, who moved up to sixth in the FedExCup.

“He started off playing great,” Rahm said of Palmer. “I kind of struggled and then I came through in the middle and then he finished it up.”
