Davis Riley and Nick Hardy earned their first PGA Tour wins on Sunday by securing the Zurich Classic of New Orleans with a tournament-record score of 30 under par.

The American duo shot scores of 64 and 63 in their four-ball rounds on Thursday and Saturday, and they also excelled in the foursomes format, posting 66 on Friday before closing with a seven-under 65.

With five birdies from their last eight holes, Hardy and Riley broke two strokes clear of the chasing pack, eclipsing the scoring record of 29 under set by the team of Patrick Cantlay and Xander Schauffele just last year.

For their efforts, Hardy and Riley earned $1.24million each, along with a massive jump into the top 40 of the FedExCup rankings.

Two strokes behind in outright second place was the Canadian team of Adam Hadwin with Nick Taylor, who posted a final-round 63 to tie the tournament's foursomes scoring record, which Cantlay and Schauffele set on Friday.

Wyndham Clark and Beau Hossler enjoyed an outright third finish at 27 under, while defending champions Cantlay and Schauffele were joined in fourth at 26 under by Matthew NeSmith with Taylor Moore.

The team of Keith Mitchell with Im Sung-jae came into Sunday's play at 25 under and finished the same way, blowing a golden opportunity to threaten the leaders, while the impressive young South Korean duo of Tim Kim and Kim Si-woo banked a top-10 finish at 23 under.
