England’s Paul Waring shot an eight-under 63 to move into a tie for the lead with South Africa's Hennie Otto making it a front group of three.
Scotland's Chris Doak and Austria's Bernd Wiesberger are one shot back.
"I think the lovely weather's had a bit of a hand in it. I played nice, kept control of my golf ball well, hit it close a few times and holed a few putts," said Waring.
"I've been playing better for the last few months; I lost by one in Valencia, two in Gleneagles, been knocking on the door a few times so it's nice to keep myself in contention week on week."
