Jon Rahm let slip a two-shot lead late in the third round as Danny Willett regained a share of the lead at the BMW PGA Championship.
Rahm edged two clear of his playing partner with two to play, but he bogeyed the 17th and narrowly avoided another slip at the last, which Willett bogeyed to join the Spaniard on 15 under heading into the final round at Wentworth.
The top two have a three-stroke advantage over Justin Rose, Christiaan Bezuidenhout and Shubhankar Sharma, while Rory McIlroy gave the early risers plenty to cheer when he fired a superb 65 to propel himself 40 places up the leaderboard, although he will begin his final round a distant nine shots off the pace.
Rahm gained the early advantage with a two-shot swing at the first, where Willett was unable to get near the green in two from the rough and bogeyed, with Rahm opening with a confident birdie.
Willett bounced back with a birdie at the third and, although he was unable to match Rahm’s four at the fourth, the Englishman regained a share of the lead with birdies at the sixth and seventh.

Willett ignored the adventures of his playing partner and closed out his 68 with a six-foot putt for birdie, while Rose would have been frustrated to end the day three behind after he made a mess of the final hole moments after chipping in for eagle at 17.
Rose, who on Friday outlined his determination to win one of his “bucket list” events, stayed within striking distance of the top two with three birdies over the first six holes, while carding only his third bogey of the week at the fifth.
The world no 3 made the same mistake as Rahm at the 10th and was also unable to save par from the trees, and he missed out on a bounce-back birdie at 12 before belatedly getting back to 11 under with a good three at the tough 15th.
Rose then propelled himself firmly back into the reckoning when his powerful second with a fairway-wood at the 17th trickled off to the right of the green, and he chipped in for eagle to get within three of the leader.
But he was inches from pitching into the water at the last after going long with his bold second from the fairway, and the two-time runner-up then needed three to get down as a closing bogey-six took the gloss off his 69.
Bezuidenhout briefly shared the lead on 11 under when he birdied two of the first four holes, but the Andalucia Masters champion did not pick up another shot until the 10th and frittered it away when a poor drive at 13 led to his first bogey of the day.

The South African steadied himself with a run of pars before making a nice four at the 17th, and a solid par at 18 completed a 69 for his third sub-70 score of the tournament.
Sharma, whose world ranking has tumbled to 283rd after a disappointing 2019 so far, stormed into the mix when he made his ninth birdie of the day at the penultimate hole, but a fluffed chip from the greenside rough at the last led to his third bogey, which was an unfortunate ending to an otherwise superlative 66.
