Matt Wallace set the clubhouse target as he delighted the home fans with an opening 67 on day one of the Sky Sports British Masters.
The Englishman already has three European Tour wins to his name this season to sit 19th on the Race to Dubai Rankings presented by Rolex and he continued that fine form at Walton Heath Golf Club.
Wallace carded six birdies, an eagle and three bogeys to sit at five under, a shot clear of countryman Richard McEvoy, Swede Joakim Lagergren and Frenchman Mike Lorenzo-Vera.
American David Lipsky made the best start of the afternoon wave, birdieing four of his first six holes to join the group a shot off the lead.
Wallace eagled the 11th and a birdie from ten feet on the 15th got him within one of early leader Jordan Smith but a roller coaster was to follow.
He dropped a shot on the 16th but hit an excellent tee-shot into the par three next before three-putting the first. A brilliant second into the par five second with a driver set up a birdie and a 20-foot putt on the third put him into the solo lead at four under.
Another birdie on the sixth and a brilliant approach to the eighth meant he was two ahead but with the pack jostling behind him, when the 28 year old dropped a shot on the ninth he was in a four-way tie.
Lagergren had bogeyed the third and fourth but made a birdie on the sixth and then six in seven holes from the eighth, with an 18-footer on the 14th getting him to five under before he dropped a shot on the 16th.
Malaysia's Gavin Green had gains on the second and sixth but a hat-trick of birdies from the tenth put him in that share before he failed to get up and down from just in front of the 15th green and dropped a shot on the 17th.
2008 Masters Tournament winner Trevor Immelman made four birdies and three bogeys in a roller coaster first ten holes but birdied the third, fourth, fifth and seventh to join the lead before a bogey-bogey finish.
McEvoy went birdie-bogey on the 12th and 13th but made gains on three of the next four, with a beautiful tee-shot on the 17th getting him to three under. A bogey on the fourth stalled his progress but birdies on the sixth and ninth moved him into second.
Lorenzo-Vera had been one over after ten holes but an eagle on the par five 11th kick-started his round, with birdies following on the 14th, 16th and last.
Green and Immelman were joined at three under by 2015 champion Matthew Fitzpatrick, fellow Englishmen Matthew Southgate and Andy Sullivan, Swede Alexander Björk and Frenchman Clément Sordet.
Fitzpatrick and Sordet had both held the lead during the morning, with Sordet making four birdies and a bogey, and Fitzpatrick recording an eagle, three birdies and two bogeys.
Sullivan made an eagle, four birdies and three bogeys, while Björk and Southgate both had five birdies and two bogeys.
Defending champion Paul Dunne was in the group three shots off the lead, while tournament host Justin Rose was two over after a 74.
