Alexander Noren will take a three-shot lead into the final day of the British Masters after carding a round of 65 on Saturday.
The Swede had begun the day one stroke behind overnight leader Richard Bland but an unblemished round, that included six birdies, moved him on to 16-under par for the tournament.
The world number 26, who is chasing a third victory on the European Tour this year following his successes at the Scottish Open and the Omega European Masters, produced a particularly strong finish at The Grove, following up a birdie at the 17th with a successful 45-foot putt at the last.
The 34-year-old admitted after his round that it is always nice to end a day on a positive note.
He said: "Obviously on 18, it was an amazing feeling because I thought it was a tough putt, and you can easily three-putt that and come off with a sour taste in your mouth. Now it feels great. I've three-putted those a lot of times, so sometimes you've got to get lucky.
"I know from experience that it's not that easy to hold leads. Anybody can come from behind and shoot eight-under. You never know."
Englishman Bland holds second position on his own on 13-under, while Peter Hanson, Bernd Wiesberger, Richard Sterne and Tommy Fleetwood are all a further shot off the pace.
