Bjorn blips lets others in

Thomas Bjorn threw the BMW PGA Championship wide open on Sunday with a triple-bogey seven on the sixth hole of the final round at Wentworth.

Bjorn began the day with a five-shot lead over two-time winner Luke Donald and although Shane Lowry reduced the gap with an eagle on the fourth and birdie on the fifth, Bjorn was still four clear when he birdied the fourth.

However, the 43-year-old Dane then failed to get up and down from a greenside bunker on the fifth and found even worse trouble in sand on the next.

Bjorn failed to escape from a fairway bunker at the first attempt and only a nifty bit of footwork prevented the ball rebounding back and hitting his left foot, which would have meant a one-shot penalty.

After splashing out of the sand with his third shot, Bjorn found a greenside bunker with his approach and needed three more shots to finish the 418-yard par four.

That left the former Wentworth resident tied for the lead with Lowry on 12 under par, with Rory McIlroy just two behind after one eagle, one birdie and one bogey in his first seven holes.

Scotland's Stephen Gallacher was producing the best golf of the day with six birdies in 14 holes - four of them in succession from the 11th - taking the Dubai Desert Classic winner to nine under.

A bogey from Lowry on the ninth left Bjorn out in front once more, but a

rollercoaster final round soon took another twist.

Bjorn also dropped a shot on the ninth after coming up short of the green with his approach and Lowry promptly holed from 20 feet for a birdie on the 10th, the two-shot swing taking the former Irish Open winner into the lead.

McIlroy had fallen three off the pace with a bogey on the ninth but chipped in for birdie on the 10th to remain firmly in contention.

Lowry also birdied the 11th and 12th to briefly enjoy a three-shot lead, but McIlroy birdied the 13th and Bjorn the 12th to both get within two.

And when Lowry drove into trouble on the 13th to run up a double-bogey six, there was a three-way tie at the top on 12 under par.
