Jordan Smith delighted the home crowds as he turned in 32 to take the early lead on day one of the Sky Sports British Masters.
The Englishman made four birdies on the back nine at Walton Heath Golf Club to get to four under, a shot ahead of countrymen Richard McEvoy and Matt Wallace, and Frenchman Clément Sordet.
Smith's rise was meteoric after turning professional in 2014, winning the PGA EuroPro Tour in 2015, the Challenge Tour in 2016 and his first European Tour title at the 2017 Porsche European Open.
McEvoy's career was more of a slow-burner and when he replaced Smith as Porsche European Open champion in July, that was his first win in his 285th appearance.
Wallace is three-time winner on the European Tour this season, while Sordet is fighting to keep his playing privileges after finishing second in last season's Challenge Tour Rankings.
Smith birdied the 11th and 12th, another gain on the 14th gave him the solo lead and when he made a fourth birdie of the day on the next, he was two clear.
Wallace had eagled the par five 11th and a birdie from ten feet on the 15th had him within one before he dropped a shot on the 16th but bounced back on the next.
McEvoy birdied the 12th but gave the shot straight back before making gains on the 14th and 16th, and hitting a stunning tee-shot on the par three 17th.
Sordet had birdies on the second, fourth and eighth as he turned in a bogey-free 33 playing the front nine.
Major Champion Trevor Immelman, England's Oliver Fisher and Spaniard Pablo Larrazábal were at two under, a shot clear of a group containing reigning champion Paul Dunne and 2015 winner Matthew Fitzpatrick.
