Tommy Fleetwood turned in 34 to share the lead at 13 under alongside Wade Ormsby atop a congested leaderboard in the final round of the Omega European Masters.
The Englishman picked up two birdies on the front nine to sit with Australian Ormsby, who turned in level par, but there were seven players just one back.
Overnight leader Andres Romero, Spaniard Adri Arnaus, Malaysian Gavin Green, Australian Lucas Herbert, Finn Kalle Samooja, Austrian Matthias Schwab and Swede Sebastian Soderberg were all 12 under.
Romero failed to get up and down from a greenside bunker on the first and with playing partner Ormsby hitting a stunning second to 15 feet, there was a two shot swing and a new leader.
The lead was soon shared as Ormsby found trouble down the right and dropped a shot on the second, with the flying Arnaus moving just a shot back.
The 24-year-old made one of just four birdies on the first all day before taking advantage of the driveable sixth and seventh, hitting a tee shot to seven feet on the eighth, and picking up another shot with a tap-in on the par five ninth to turn in 30.
Romero could not get up and down from greenside rough on the third and Ormsby led alone as Fleetwood missed a good birdie chance, with the 2017 Race to Dubai Champion bogeying the next.
Arnaus also found himself in the group at 11 under as he bogeyed the 11th and there were seven players within two shots of the lead.
Fleetwood got himself back to level par for the day and 12 under for the week with a 15 foot left to righter on the fifth, and he was in solo second as Romero dropped a shot after going a long way left off the tee.
Schwab then joined him at 12 under as he recovered from a birdie at the second with gains on the short fifth and seventh, and an excellent approach to two feet at the tenth.
Ormsby would have been disappointed to not take advantage of the gettable fifth, sixth and seventh but he drained a 20 footer on the par three eighth to extend his lead to two.
There was soon eight players in the chasing pack, though, as the birdies came thick and fast.
Herbert had made two birdies on the front nine and went eagle-birdie-birdie from the 14th to catapult himself up the leaderboard, while Samooja bounced back from an opening dropped shot with gains on the eighth and ninth.
Green's comeback was even more impressive as he bogeyed the third, fourth and seventh but he had made a gain on the fifth and hit a stunner to ten feet on the ninth to set up an eagle.
Soderberg had bogeyed the first but he picked a shot up at the seventh, chipped in at the tenth and holed a long putt at the 11th, with Arnaus adding to his earlier birdies at the 15th.
Ormsby sent his second on the ninth right to drop a shot and with Fleetwood taking advantage of the par five with a left to righter, there was a tie at the top.
Romero also birdied the par five to get to 12 under.
Belgian Thomas Pieters was the clubhouse leader and had Italian trio Lorenzo Gagli, Renato Paratore and Andrea Pavan for company at 11 under.
