Paraguay’s Fabrizio Zanotti was the surprise leader of the French Open after a sparkling three-under-par 68 on Friday lifted the 30-year-old into a one-shot lead after two rounds of dramatic action at Le Golf National.

The South American, who is looking for his first ever victory on the European Tour, racked up four birdies before holding his nerve down the stretch to stand clear of the field heading into the weekend’s final two rounds.

“On a course like this, I think you have to accept everything. It’s playing very tough and the greens are getting hard, so it’s going to be very difficult,” said a delighted Zanotti.

Danish duo Thomas Bjorn and Soren Kjeldsen, along with South African Richard Sterne, are joint second on five-under. But overnight leader Anders Hansen, also of Denmark, slumped down the leaderboard with a horrid round of 78.

He finished the day on two over but eight shots back of Zanotti.

Bjorn, who famously collapsed at the 2003 British Open when he blew a two-stroke lead with three holes to play, endured another frustrating day when he bogeyed the final two holes after seizing a two-shot lead thanks to five birdies through 16 holes.

Stern, who won his ninth tournament earlier this year when he took the honours at the Johannesburg Open, is again set to challenge for the title at the 97th edition of a tournament set to host the 2018 Ryder Cup.

Kjeldsen followed his opening round of 69 with a almost flawless round of 68 that featured four birdies and just one bogey as the 38-year-old from Aalborg targets a fourth European win and first since his triumph at the Open de Andalucia in 2009.

In a crowded leaderboard, Northern Ireland’s Graeme McDowell, English duo Simon Dyson and Graeme Storm, as well as Scotland’s Stephen Gallacher were all locked on four under and two shots adrift.

Australian Richard green was a shot further back after shooting 69-70.

Meanwhile, American world number five Matt Kuchar survived the cut despite a four-over-par 75.
