Hend had produced one of the best pars of his round at the par five, ninth hole when his second shot was way right into trees from where he managed to find the green with a deft tee shot under branches and onto the back of the green from where he two-putted from just over a metre for par.
Both carded 14-under totals of 266 having had early starts Sunday to complete their delayed third rounds. It's never nice to see, but we kept our nerve and just played really smart all week.
The 48th-ranked Englishman sank his putt from less than three feet (one meter) while Scott Hend of Australia made a ragged bogey at the 18th hole on the scenic Swiss Alps course. On Saturday, play was suspended because of fog, while fading light brought the leading groups in early.
He lost the same event in a play-off to Alex Noren past year and will rue missing his putt on the second additional hole, costing him the chance to land a third European Tour title.
Both players were tied for the lead at 14-under to go into a play-off.
Swede Alexander Björk, Thai Thongchai Jaidee and South African Richard Sterne were all at eight under with holes to complete when play resumes at 8.00am on Sunday morning.
"I'm delighted", said Englishman Fitzpatrick.
Two weeks off has worked a treat for Ryan Fox, who sits one shot off the lead in a share of fourth at the European Masters in Switzerland.
The 44-year-old Hend struck a magnificent iron shot to six feet from the pin, only to pull his putt for a third European Tour victory past the lip.
Tyrell Hatton (66) and Fabrizio Zanotti (68) were tied for third spot, while Mikko Ilonen (64) was fifth and defending champion Alex Noren (66) was among three players tied for sixth.
Lee Westwood, the 1999 victor at the Crans-sur-Sierre club that is blanketed with snow each winter, finished on level par after a closing 69.
