Suzann Pettersen was crowned Deutsche Bank Ladies Swiss Open champion on Sunday after the fourth and final round of the competition was cancelled due to a water logged course at Golf Gerre Losone.

Tournament organisers took the decision to reduce the event from 72 to 54 holes at 11am on Sunday as many of the fairways and greens were flooded after heavy rainfall, making the course unplayable.

With the fourth round cancelled, the results at the end of round three were final. Pettersen’s winning total of 194, 22-under-par, broke the Ladies European Tour’s record for the lowest winning 54-hole aggregate. This previously stood at 190 (-17), having been set by French woman Karine Icher at the 2004 Catalonia Ladies Masters. Pettersen revealed that she had been aiming to go much lower than that and beat Laura Davies’ record of 25-under for 72 holes, set at the 1995 Guardian Holidays Irish Open at St Margaret’s.

Pettersen, the world number three, led the way with rounds of 67, 63 and 64 to earn the first prize of €78,500. She dedicated her prize to a 24-year-old family friend who passed away on Monday.

Alexandra Armas, executive director of the Ladies European Tour, added: “I think it’s been a fantastic week of scoring. There are a lot of birdies out there and I think a lot of players would have gone out strong to try and move up the leader board. We can’t help the weather. It is a golf tournament and it is about the golf.”

Hanns Michael Hölz, head of corporate sports at Deutsche Bank, the title sponsor of the tournament, added: “Normally the Ticino region is known as the sunny terrace of Switzerland but sometimes maybe because of climate change, it has become more like the rain terrace. These things happen. In my view, I think it was a great sports event and we had some spectacular golf.”
