Runaway halfway leader Julien Guerrier saw his advantage reduced to three shots in the early stages of his third round on Moving Day at the 2020 Portugal Masters.
The Frenchman began the day with a five shot lead after adding a second round 66 to Thursday's spotless 62 but had been reined in ever so slightly by playing partner Sihwan Kim after four holes on Saturday.
Guerrier opened his third round with a stunning up-and-down from a bad lie in the rough at the first before narrowly missing lengthy birdie putts at the second and third to stay on 14 under par.
He was unable to keep a bogey off the card at the fourth despite a lovely bunker shot, with his 12 foot par putt just missing the hole.
Kim, meanwhile, made a birdie from 15 feet on the third to jump to ten under.
Wilco Nienaber was a further shot back in a tie for third after holing his approach into the fifth for an eagle. Niklas Lemke and Laurie Canter were also on nine under.
John Catlin, who claimed his maiden European Tour title at last week's Estrella Damm N.A. Andalucia Masters, moved into contention early on day three, with a bogey free 65 taking him to seven under par.
