Marcel Siem's fast start keeps him one ahead of Matt Fitzpatrick at The Belfry
Marcel Siem holds a one-shot advantage heading into the weekend at the Betfred British Masters, after carding a 69 to follow his opening 66 on Friday.
The Englishman, who is hoping to catch the eye of European Ryder Cup captain Luke Donald before he makes his picks for next month's biennial showpiece in just over one week, did his chances no harm as he carded an eagle, four birdies and two bogeys to reach 12 under par.
That saw the Major Champion claim the outright lead after 54 holes but Fitzpatrick will have another former winner of this event on his tail on Sunday, with Swede Alex Noren his nearest challenger on 11 under.
Last week's winner Marco Penge continued his fine form as he carded nine birdies and no bogeys in a flawless third-round 63 on home soil to equal the course record at The Belfry Hotel & Resort.
The Englishman sits alongside Nicolai Højgaard in a tie for third, two shots off the lead, while Scottish amateur Cameron Adam is among the group another stroke back after his bogey-free 66.
Fitzpatrick started the day one shot off the lead but was already two behind by the time he teed off after Penge's brilliance early in the day.
The 2015 champion opened his birdie account from six feet at the par-five third but gave the shot back at the sixth.
He bounced back immediately by taking advantage of the par-three seventh before holing from ten feet for another birdie on the tenth.
He bogeyed the 11th but once again got the shot straight back at the 12th courtesy of a 25-foot birdie.
Home favourite Matt Fitzpatrick will take a one-shot lead into the final round of the Betfred British Masters hosted by Sir Nick Faldo after signing for a Saturday 68 which featured a chip-in eagle.
But the best was still to come as Fitzpatrick holed his chip at the 15th for an eagle to take the outright lead.
And although he had further birdie chances coming in, Fitzpatrick had to settle for a hat-trick of pars and a slender one-shot lead over Noren.
Speaking about the prospect of winning this event for a second time, Fitzpatrick said: "It would be amazing.
"To do it ten years apart would be pretty cool, too, I think. Looking forward to the opportunity.
"As I was out there today, it's just really enjoyable to be in these situations. Scottie Scheffler must be absolutely buzzing every week.
"It's really nice to be in contention, playing solid and give yourself a chance of winning a golf tournament."
Noren, who made an eagle and five birdies in his spotless 65, said: "It feels amazing.
"I struggled yesterday and the first day. I scored well the first day, and then talked to my coach, needed to work on some stuff.
"Came here a little bit earlier this morning, which I never do before a late round. It paid off today."
Angel Hidalgo produced early fireworks on day three as he made a slam-dunk hole-in-one at the seventh hole on Saturday morning.
