Joaquin Niemann extended his lead at the Genesis Invitational to three strokes after an eagle on the 10th hole on the third day at the Riviera Country Club in Pacific Palisades, California.

The Chilean, who led after both of the first two days, carded a six-under-round of 68 to be 19-under overall, meaning his 194 across 54 holes is a course record. He leads from Cameron Young who is 16-under.

Young's double bogey on the 16th hole opened up a big gap at the top, with Viktor Hovland moving into third with a six-under-65 but he is six shots behind Niemann at 13-under.

Niemann carded four birdies on the front nine, before the highlight of his day with an eagle on the 10th after an aggressive drive.

The eagle took world number 32 Niemann to 21-under before two bogeys in his final seven holes, although Young was unable to make any major inroads.

Norwegian world number four Hovland was the big mover on Saturday, with five birdies on the front nine, although bogeys on the 14th and 15th slowed his charge.

Former PGA Championship winner Justin Thomas is one stroke behind the Norwegian after a one-under-70, while second-ranked Collin Morikawa is a further shot back after his three-under-68 took him to 11-under overall.

Last week's Arizona Open winner Scottie Scheffler also managed a six-under-round to be tied on 10-under alongside Maverick McNealy, Marc Leishman and Max Homa.

Rory McIlroy carded a four-under-67 to be seven-under and tied in a large group that includes three-time major champion Jordan Spieth who struggled with a two-over-73 with three bogeys and one birdie for the day.

Scottie Scheffler edged Patrick Cantlay in a three-hole playoff to clinch the Phoenix Open title marking a dramatic turnaround after narrowly avoiding the cut on Friday.

World number 15 Scheffler and reigning PGA Tour Player of the Year Cantlay faced off after both finished 16-under-par following final day rounds of four-under-67.

Scheffler, who avoided the cut by one stroke, claimed the title with a birdie on the third hole of the playoff as Cantlay could only make par.

The 25-year-old American, who resides in Dallas, landed his second shot from the bunker on the green, before sinking a 26-yard putt for the decisive birdie, with Cantlay unable to match that.

The victory marks 2021 US Ryder Cup team member Scheffler's first PGA Tour title, having finished in the top 10 of three majors last year.

Scheffler had birdies on the 15th and the 17th holes to force his way into a playoff, although he almost won it outright on the 18th but missed a birdie putt from five feet.

Overnight leader Sahith Theegala found the water off the tee on the penultimate hole leading to a bogey that saw him slip from the lead.

Four-time major winner Brooks Koepka stormed into contention late, with three birdies and a bogey on his final four holes but fell short of the playoff.

Koepka and Theegala finished tied for third with Tokyo Olympics gold medalist Xander Schauffele at 15 under.

Scheffler had surged up the leaderboard on the third day with a nine-under-62 and backed that up with another strong round on Sunday.

Louis Oosthuizen and Charl Schwartzel turned in a nine-under 63 in four-ball play to take the lead after the third round of the Zurich Classic of New Orleans. 

The South African duo are 19-under for the tournament and were one of six teams to record a 63, vaulting them past second-round leaders Tony Finau and Cameron Champ by a stroke. 

Australians Marc Leishman and Cameron Smith also shot nine-under and are tied for second with the American pair. 

The top of the leaderboard at TPC Louisiana is crowded, with Bubba Watson and Scottie Scheffler sitting two shots back along with first-round leaders Viktor Hovland and Kris Ventura. 

The tournament, which switched to a team event in 2017, features four-ball in the first and third rounds and foursomes in the second and fourth. 

Three teams are at 16 under and nine more at 15 under, with the latter group including defending champions Jon Rahm and Ryan Palmer. 

The shot of the day belonged to Sam Ryder, who holed a five iron from 206 yards at No. 2 for a double eagle -- the first at the tournament since Rob Oppenheim did it in 2018.
