Frenchman Victor Riu was two shots clear heading into the final nine holes of the Swiss Challenge, but Englishman Adam Gee and Korean Sihwan Kim were hot on his heels.
Riu was one over par at the turn, just keeping Gee, three under through nine holes, and Kim, five under through 12, at bay.
Jamie McLeary, who was Riu’s closest challenge at the start of the final round at Golf Sempachersee, was two over approaching the halfway point and had slipped back into a share of eighth place.
South African Dylan Frittelli, who won in Austria a fortnight ago, earlier finished with a 63 to rise up the leaderboard to eight under par overall.
