Marc Leishman has jumped up the leaderboard after back-to-back birdies at 7 and 8. He’s now at +2, where he’s rejoined by Patrick Cantlay, who’s slipped back after a sloppy three-putt at the short 4th.

Collin Morikawa had a dreadful day yesterday, carding a 77 after starting in a tie for the lead. He’s back out there now and is level through his opening three holes after missing a makeable birdie putt.

Tarren holes a lovely putt from the fringe at 14 for a birdie. He’s -2 for his round and now up into a tie for 34th. The Englishman, who is ranked No 445 in the world, has only ever had one top 10 finish on the PGA Tour before, and that came in a weakened field at the Puerto Rico Open in March. This is a great performance and comeback after such a disappointing day yesterday.

Patrick Cantlay has endured a bit of a slump by his own high standards this year but the American is up into a tie for 11th after a fine start to his final round. Birdies at 1 and 2 have taken him to +1 and he’s managed to find the green at the tricky 3rd.

Not a great start for Jordan Spieth, who pulled a 10ft birdie putt at the first and then bogeys the second after missing the green short and right at the long par 3.

Thomas couldn’t hole that short one for par at the first either and has slipped back to +4. He will have the chance to make amends at the third, though, after a great blind approach that runs up to the green and settles about 15ft from the flag.

Mackenzie Hughes and Patrick Cantlay are both off to bright starts in their final rounds and are now at +2, six shots back of the lead.

England’s Callum Tarren endured a torrid third round after leading by two shots at one stage on Friday. He’s recovering well today though and is one under through 13 and in a tie for 45th at +6.

Justin Thomas hasn’t had the week he’s wanted, having come into the tournament in such a great run of form.

The PGA champion has just got his final round underway but pulls his approach at the first left and is forced to hit a wonderful flop shot over the greenside bunker. There’s still a bit of work left to save par though. He’s currently +3.

To say Grayson Murray is not a happy bunny out there would be somewhat of an understatement. The American, who is nine over for his round through 12 holes, has laid waste to his wedge.

Despite most of the players out on the course currently struggling, there are still certainly opportunities to go low.

One person proving that is Guido Migliozzi. After birdieing three of his opening five holes, the young Italian has just eagled the par-5 8th with a fine putt from 11ft. He’s now +2 for the tournament which is a very respectable tied-17th.

It’s been a tough afternoon for Koepka’s arch-rival Bryson DeChambeau too. The American is three over for his round. His next outing will, of course, be at the controversial LIV Golf event in Portland in a fortnight’s time.
