DOHA, Qatar (AP) Denmark's Thomas Bjorn shot a 6-under 66 Saturday to take a one-shot lead into the final round of the Qatar Masters.
Bjorn birdied four of the last five holes to finish at 11-under 205. He leads overnight leader Markus Brier, who had a 69. Defending champion Robert Karlsson finished with a 69 and trails the leader by two shots. He had five birdies in six holes to finish with a 31 on the back nine.
Martin Kaymer had a 68 and is 10 shots behind Bjorn. He needs a second-place finish to overtake Lee Westwood at the top of the rankings. Westwood missed the cut on Friday.
Bjorn, who shot a 74 on the opening day before coming back with a 65 on Friday, picked up shots at the first and seventh holes. He added a late birdie spree at the Doha Golf Club.
"When you finish a round with four birdies in the last five, you have to walk off very happy," Bjorn said. "I played fantastic yesterday and felt comfortable this morning."
Austria's Brier was even with Bjorn with a hole to play, but sent his drive right. He needed four to reach the green and two-putted for a bogey on the 18th.
"It was a lot of good things, except the par 5s, which I had two bogeys and two pars," Brier said. "But the rest was really good. Still up there."
South Africa's Thomas Aiken shot a 69 to trail by four shots. England's Richard Finch (71) and 2009 champion Alvaro Quiros of Spain (66) are five shots back.
