Abu Dhabi, United Arab Emirates (My Sportsbook) - Paul Casey fired a bogey- free, nine-under 63 Saturday to take a four-stroke lead after three rounds of the Abu Dhabi Championship.

Casey completed 54 holes at 19-under-par 197. His three-round total broke Martin Kaymer's record of 199, which the German set last year. Casey, an eight-time winner on the European Tour, collected his last title at this event in 2007.

Kaymer, the defending champion, fired a seven-under 65 to move into second place at 15-under-par 201.

Englishmen Graeme Storm and Anthony Wall are alone in third and fourth. Storm, who shared the lead after the second round, carded a three-under 69 and stands at 14-under-par 202. Wall also shot 69 and is one stroke further back at minus-13.

The tournament is back on track after the second and third rounds were completed Saturday. There was a two-hour delay during the first round that pushed the tournament back.

Casey got off to a quick start with birdies on one and two. After four straight pars, he birdied the par-three seventh at Abu Dhabi Golf Club to move to 13-under.

The Englishman then picked up his third birdie in three days at the par-five eighth. He also birdied the par-five 10th thanks to a 40-foot birdie putt.

"That was the turning point, I think," said Casey, whose drive on 10 was under a tree. "On the second shot, I didn't know where the ball was going to go and I didn't know whether I would break my club."

Casey kept rolling with back-to-back birdies from the par-three 12th. He parred three in a row from the 14th, but closed with a flourish.

The 31-year-old birdied the 17th get to 18-under, then birdied the par-five 18th for the third consecutive day to set the new 54-hole scoring record by two strokes.

"I didn't expect much after (Friday's) 65. It was nice playing with Graeme, who is actually a good friend," stated Casey. "We all got off to a great start. I think it's always enjoyable to shoot 63"

Kaymer opened with six straight pars before making birdie at No. 7. He then eagled the par-five eighth to jump to 11-under.

Around the turn, Kaymer dropped in back-to-back birdie efforts from the 11th and again from the 17th to move into second place.

"I think it's going to be a totally different situation for me," said Kaymer in comparing last year's final round with Sunday's finale. "I was in the lead by six shots last year when I went out on Sunday, and it was a similar situation. It's going to be very new for me."

Peter Hanson fired a six-under 66 to climb into a share of fifth at 12-under- par 204. He was joined there by Louis Oosthuizen (68) and Johan Edfors (69).

Padraig Harrington, the reigning British Open and PGA Championship winner, is part of a group tied for eighth place at minus-11. He stands alongside Oliver Fisher (69), Stephen Gallacher (65) and Danny Willett (68).

Australian Richard Green, who shared the lead with Storm after the second round, stumbled to a four-over 76 that dropped him into a share of 28th at seven-under-par 209.
