World number one Scottie Scheffler, Collin Morikawa and Justin Thomas all missed the cut at the Scottish Open as Matt Fitzpatrick and Xander Schauffele moved into contention behind leader Cameron Tringale.

Masters champion Scheffler followed up a three-over 73 with a 72 for the second round, putting him 12 strokes behind Tringale, who came back down to earth with a 72 following his stunning nine-under 61 in the opening round, failing to recover after a run of five bogeys in six holes.

Morikawa, who will defend his Open title at St Andrews next week, will also miss the weekend following a four-over 74 that took him to five over. He made the turn four over and a further bogey at the second, and a double at the fourth cancelled out three birdies on his back nine.

US PGA champion Thomas endured a nightmare day at The Renaissance Club, carding eight bogeys and a double for his 77, which dropped him to 10 over par.

World number eight Viktor Hovland, Will Zalatoris and Hideki Matsuyama also missed the cut, as did Ian Poulter, playing on the co-sanctioned DP World Tour and PGA Tour event despite his defection to LIV Golf. Poulter finished 10 over.

But U.S. Open champion Fitzpatrick and Schauffele remain firmly in the hunt.

They are each four shots off the pace, though Fitzpatrick's 66 would have been even better if not for successive bogeys on his final two holes.

Schauffele went one better with a 65, his round starting at the 10th with an eagle and ending with a well-executed chip in for birdie at the par-three ninth.

Jordan Smith is also three under after his second round, the Englishman winning himself and his caddie a car with a hole-in-one on the 17th, only to follow it with a closing bogey and card a 69.

Tringale's American compatriots Gary Woodland and Doug Ghim are his closest challengers on four under.

Ghim is in position to secure a place at St Andrews as the highest-placed player not already sure of a place in the field. Kurt Kitayama (three under) and Rafa Cabrera Bello (two under) would also qualify as it stands.

Cameron Tringale was delighted with his "red-hot" putting display after shooting a remarkable nine-under 61 to take the lead at the Scottish Open, matching the course record in the process. 

Tringale reached the turn at three-under after making a steady start, but the 34-year-old – whose only previous professional victory came in the Franklin Templeton shootout team event in 2014 – picked up the pace to birdie six consecutive holes through 10 to 15 and finish day one top of the leaderboard.

The American ended Thursday three shots clear of compatriot Gary Woodland and four ahead of South Africa's Justin Harding – one of four LIV Golf players to feature at the Renaissance Club in North Berwick.

In claiming a place among the early leaders, Harding fared far better than fellow LIV Golf star Ian Poulter, who made nine bogeys during a calamitous opening round to finish eight-over.

Poulter was allowed to feature pending an appeal against a DP World Tour ban but may be wishing he had not bothered after slumping to near the bottom of the leaderboard, at one point sharing last place in the expanded field.

But the story of the day was undoubtedly Tringale's career-best round. He is now targeting greater consistency after setting a terrific pace. 

"I got lucky this morning with the wind not being up, the other guys in my group were off to hot starts, making some putts and I decided to join the fun on number five," Tringale told Sky Sports. 

"Then my putter got red-hot, and that's how you do it!

"You do the best you can, I think I was just fortunate with the amount of putts I holed and I got plenty of practice shots around the green, I didn't have to use them all that much because I struck it pretty nicely.

"But I was just dialled in on the greens and that tells the story. I'm just really focused on what I can control, I've done it poorly enough to learn the lessons. 

"Hopefully I can continue to go and play, and the good outcomes will come as a by-product if I can keep my head on straight."

Patrick Cantlay holds a two-stroke lead after the second round at the RBC Heritage following a four-under par 67.

After posting a bogey-free 66 on the first day, the world number six's second round featured three bogeys, but he closed it out with four consecutive birdies starting on the par-five 15th hole to tie for the best round of the day.

Over his first two rounds, Cantlay has birdied 10 of the 18 holes at Harbour Town.

Speaking to the media after his round, Cantlay explained that his finish was exactly how he wanted to head into the weekend.

"Obviously, that's a dream finish," Cantlay said. "I finally rolled in some putts and that was really nice to see going into the weekend.

"Just staying with my game plan and continuing to leave the golf ball in the right spots, which is paramount around this place, I think is the key."

Six players shot 67 on Friday, including second-placed Robert Streb, who is alone at seven under.

First-round leader Cameron Young could not come close to repeating his unbelievable round of 63, going 10 strokes worse, but he is still very much in the mix in a tie for third at six under with a group of players including Cameron Tringale and Erik van Rooyen.

Chilean pair Joaquin Neimann and Mito Pereira are one shot further back at five under, along with Jordan Spieth, while Corey Conners and Shane Lowry have continued their fine form from The Masters to be in the hunt at four under.

Pre-tournament favourite Collin Morikawa posted his second consecutive 70 to sit in a tie for 34th at two under, but blew a chance to go into round three in the top-20 after double-bogeying the 18th.

Justin Thomas finished one stroke better than the cut-line at one under, while reigning champion Stewart Cink held on to see the weekend at even par along with Webb Simpson and Danny Willett.

Cameron Smith's Masters hangover saw him finish one over, missing the cut along with Dustin Johnson, who followed up Thursday's 72 with an equally disappointing 71.

Other notable names to drop out include Kevin Kisner, Russell Henley and Matt Fitzpatrick, with the latter carding 75 to fall three strokes short.

Luke List has had a long wait for his first PGA Tour win and that was extended after a two-hour wait before triumphing in a playoff over Will Zalatoris at the Farmers Insurance Open on Saturday.

The 37-year-old American, enjoyed an excellent final round six-under-66, highlighted by four consecutive birdies from the third to the sixth holes, to storm up the leaderboard at Torrey Pines.

But List, in his 206th career start, waited almost two hours after entering the clubhouse as the overnight leaders completed their rounds before facing Zalatoris, who also finished 15-under overall, in an 18th hole playoff.

In fading light, the pair both landed their tee shots within inches of each other in a bunker, with List's third shot placed close to the hole, enabling him to tap in to card a birdie.

Zalatoris pushed his longer birdie putt, which was near-identical to his 18th hole putt for victory that he missed, wide left again to settle the playoff in List's favour.

California-born 25-year-old Zalatoris may have clinched victory on the 18th as List patiently waited and practiced elsewhere, but was agonizingly short and slightly wide after a late fade on his putt.

He carded a final round one-under-71, grouped alongside Jason Day and Aaron Rai, with world number one Jon Rahm also making a late charge.

Day shot into a share of the lead after landing an eagle on the 14th hole but had to settle for joint third alongside Rahm and Cameron Tringale at 14-under-par overall.

The Australian, who had not won a PGA Tour title in 1,364 days, finished with back-to-back bogeys to slip from contention.

Rahm rolled in a clutch 26-foot putt to birdie the 17th to be one shot off the pace but only managed par on the last hole.

Joaquin Niemann, Justin Rose, Pat Perez, Sungjae Im and Rai were next, finishing 13-under overall.

Cam Tringale moved into the lead ahead of the final day at the 3M Open in Minnesota after carding a five-under round including an eagle on Saturday.

The American raced up the leaderboard as overnight joint leaders Ryan Armour and Adam Hadwin and slid, with an even round and two-over respectively at TPC Twin Cities.

Tringale's surge was set up after becoming only the third player to reach the par-five 12th in two, sitting at 12 under after 54 holes.

He enjoyed a bogey-free third round, birdieing his first two holes, with only Beau Hossler, who is joint for 12th, bettering his round on Saturday with a six-under-65.

Gary Woodland and Maverick McNealy are joint in second on 11 under after strong third day rounds.

Pat Perez, Cameron Champ, Jimmy Walker and Charl Schwartzel are all 10 under. Champ looms large having carded 10 under from his past 27 holes.

Rickie Fowler appeared set to contend again but carded an eight on the 18th hole to finish six off the lead having found the water.

He was not alone in struggling on the 18th which saw five bogeys, three double bogeys and seven triple bogeys or worse.
