Sweden's David Lingmerth showed the chasing pack what was possible with a brilliant course record of 62 in the third round of the British Masters.
Lingmerth made the halfway cut with nothing to spare on two under par, but surged up the leaderboard thanks to nine birdies and a solitary bogey at Close House.
That took the world number 107 into second place on 10 under, two shots behind England's Tyrrell Hatton, who was due to resume his bid for a second European Tour title shortly after 1pm.
"I'm very pleased with how my round ended up today," said Lingmerth, whose score eclipsed the previous record of 63 established by Hatton and George Coetzee on day one.
"I try to get up three hours before my tee-time so my alarm was set for five o'clock. I'm not a morning person so I need to get moving and get my blood flowing.
"I got off to a bit of a rocky start and had to save a couple of pars early, but then got rolling with the putter and made five birdies in a row from the fourth and felt like I was swinging it better too.
"Putting on these fresh greens early in the morning definitely helped. It took me a few days to get used to the greens, the speed and how to read them. I saw my lines well, putted with great speed and had a few nice ones go in.
"I don't know what the leaders will do this afternoon but I'm hoping to be somewhat near the leaders and have a chance tomorrow."
