Li Haotong produced an incredible four eagles in a remarkable third-round 62 at Saudi International to join Dustin Johnson with 18 holes to play.
In an eventful round, Li burst into life when he chipped in for an opening eagle. He then mixed two birdies with a double bogey on his way to the halfway stage before firing three more eagles on his back nine in a scintillating finish.
Johnson had led by three starting out and the American was four clear early on the back nine but a run of pars to finish his round opened the door and Li burst through in some style.
The pair are tied on 16-under par with one round to play, seemingly in a duel with England's Tom Lewis five-shots back in third spot.
Alex Levy and Ryan Fox are next on nine-under par with the likes of Ross Fisher (-8), Ian Poulter (-7) and last week's winner Bryson DeChambeau (-6) amongst those hoping to make inroads during the final round.
After his tee-shot at the 17th came to rest within five feet of the flag, Li stroked home to make it three eagles at par-fours in a one round.
He then finished the round by holing an eagle putt from eight feet at the par-five 18th to join Johnson on 16-under after a 62.
Li, now 100/1 to win the Saudi International, felt he didn't actually play that well.
"Very lucky today," he suggested. "Those eagles, especially the last couple of shots, were really solid but except that, honestly, my play wasn't that good.
"But I did make a lot of par putts.
"If it (the approach into the first) didn't go in the hole, it could have been off the green. It's a very lucky eagle over there.
"At the tenth, that's what I wanted to play, that way, but I felt like I pushed it a little bit. I got a lucky bounce, kicked it left and went in the hole, which is very lucky, too."
Johnson is 1/1000 to complete the win while Lewis is 1000/1 to come from five behind and win.
