Sam Horsfield turned in 31 to storm six shots clear on day three of the 2020 Hero Open.
After carding a 59 playing with friends in Orlando during the coronavirus hiatus, the Englishman signed for a 61 last week in the opening event of the UK Swing to show he still had the appetite to go low.
A 63 on Friday continued that trend and the 23-year-old moved to 18 under after nine holes on Moving Day at Forest of Arden Marriott Hotel & Country Club.
Spaniard Sebastian Garcia Rodriguez, Dane Rasmus Højgaard and Finn Mikko Korhonen were his nearest challengers.
Horsfield started the day in a share of a three shot lead but within three holes he was four shots clear on his own.
3 birdies in a row to start and a 4 shot lead.

He holed from 12 feet on the first and put his approach to tap-in range at the second to move to 15 under.
Playing partner Garcia Rodriguez failed to get up and down for a par on the par five third and with Horsfield making a two putt birdie, the lead was four shots.
A 15 footer on the sixth extended his lead to five shots and Garcia Rodriguez was replaced in second by Korhonen.
The joint overnight leader bogeyed the sixth, while Korhonen holed a long putt on the eighth to complete a hat-trick of gains after a birdie on the fourth.
The two time European Tour winner was soon six back, however, as Horsfield made a two putt birdie on the par five seventh.
Korhonen was joined by Højgaard as last week's runner up made a two putt birdie on the 12th to add to gains on the first, second, fifth and seventh, and another Dane was also impressing.
Joachim B Hansen had eagled the seventh but bogeys on the first and ninth cancelled out birdies on the second and fourth as he turned in 34.
A hat-trick of gains after the turn reignited his round and while he added further birdies on the 15th and 17th, a dropped shot on the last saw him slide to 11 under.
Garcia Rodriguez replaced him in second with an impressive birdie on the tough ninth.
Frenchman Benjamin Hebert was in the clubhouse alongside Hansen, with countryman Antoine Rozner, Welshman Oliver Farr and home favourite Chris Paisley also 11 under.
