ABU DHABI (AFP) - Newly-married Paul Casey shot a blistering nine-under-par round of 63 to grab a four-shot lead going into the final day of the Abu Dhabi Golf Championship on Saturday. The 31-year-old Englishman played flawless golf in a round that contained nine birdies to take his three-day tally to 19-under-par 197. Defending champion Martin Kaymer was his nearest rival after the German shot a seven-under 65 to move to second place at 201. Third-round co-leader Graeme Storm of England was one behind Kaymer at 202 following a round of 69, while Anthony Wall, also of England, shot a similar number to be sole fourth at 203. World number two Sergio Garcia moved up to a tied 20th place with a 67 while number four Padraig Harrington, winner of last year's Open and PGA Championship, was tied eighth at 204 after a third-round 68. Casey, whose last win was here in 2007, said Sundya's battle against Kaymer would be more like a club championship, since both practice at the same club, Whisper Rock in Arizona."I've never won my club championship. I think fourth was my best," said Casey.The newly-married Casey said his last two rounds (65 on Friday) were more due to the hard work he put in during the break with his putter."On Friday, Sergio and I seemed to have a contest of who could be furthest from the fairway. It wasn't very good," he said."I just didn't feel very comfortable over the ball from a technical aspect. I've always sort of prided myself on being a good striker of the ball. So when it's slightly off, I'm very critical of that," added Casey, who has nine career titles on the European Tour. "Today was much better. I hit a couple of bad shots, but made up for them with my putting. "It's really good to see the results of all the hard work I put in during the break. I played a lot of golf rather than spend time on the range as I did in the last couple of years. "And it was hours and hours of practice with the putter. I haven't putted like this, or felt this comfortable, for a long, long time." Kaymer started with six straight pars before making a birdie on the seventh and an eagle on the eighth. On the back nine, he made four more birdies. The defending champion said: "I saw Paul playing at our club in Arizona and I thought he looked really solid. So, it is good to see him playing so well. I think I will have to see how I am playing, and how he is playing, over the first few holes before making any strategy of being aggressive. "I definitely will have to shoot something similar to today to put any kind of pressure on him. But I am happy with the way I hit the ball. I am quite excited about tomorrow, because I have never been in such a position (of chasing the leader). I was ahead by six shots when I won here last year, and I had a comfortable lead in Munich when I won the BMW International."
