Louis Oosthuizen will tee off his final round at The Open on Sunday with a one-shot lead over playing partner Collin Morikawa.
The 2010 winner, who has finished as runner-up six times in majors, is eyeing a wire-to-wire victory at Royal St George's, where he starts his fourth round at 14:35 local time at 12 under.
American Morikawa also has a second major in his sights, having claimed the 2020 US PGA Championship.
Jordan Spieth is firmly in the mix, the three-time major winner and 2017 Champion Golfer of the Year at nine under, while pre-tournament favourite Jon Rahm is two strokes further back.
Corey Conners and Scottie Scheffler are each on eight under and hoping to earn maiden major triumphs.
Glorious weather means the course is set fair for low scoring for anyone who can summon the courage and accuracy to take on some tough pin positions at the Kent links.
There was promise in the early scores coming in, with American trio Rickie Fowler, Xander Schauffele and Bryson DeChambeau all shooting 65.
If any of the leading trio should go that low, it will rule out the chasing pack and reduce the contenders down to the final couple of groups on course.
That would mean Brooks Koepka's surge up the leaderboard would still leave him short, the four-time major winner having made the turn in 31.
