A DISASTROUS back nine cost Simon Dyson the chance of a top-ten finish at the BMW PGA Championship at Wentworth.

The 32-year-old York golfer birdied the seventh, eighth and ninth holes of his final round yesterday to reach the turn at one-under-par for the tournament.

However, all his good work was undone by bogeys at the tenth, 12th, 13th and 17th holes as he slipped down the leaderboard into a tie for 34th place.

The back nine proved Dyson’s undoing throughout the event as he notched 12 bogeys compared to two birdies over the course of four rounds.

On Saturday, Dyson had moved 28 places up the leaderboard to 26th with a third-round 70 to add to opening rounds of 73 and 71.

He birdied the second, fourth, ninth and tenth holes, but also dropped three shots.

The 31,950 euros earned at the PGA Championship have left Dyson sixth in the European points standings for this year’s Ryder Cup. The top four on the World points list qualify for the European team along with the next five on European points list.

The BMW-backed tournament was won by England’s Simon Khan, ranked 471st in the world and not even in the event until Monday.

The 37-year-old, from Essex, produced the biggest final-day comeback in the history of the European Tour’s flagship event as he came from seven behind to win the second most important title in European golf.

A 20-ft birdie putt on the last, which curled round the back of the cup before toppling in, gave Khan the first prize of over £637,000 by a stroke from Ryder Cup star Luke Donald and Swede Fredrik Andersson Hed.

Khan’s stunning five-under-par 66, the round of his life, also brings him a five-year tour exemption and a place in July’s Open at St Andrews.
