Paul Casey hit a 3-iron to 10 feet and holed the eagle putt to complete a bogey-free 8-under 64 in the third round of the Dubai Desert Classic on Saturday, giving the Englishman a one-stroke lead as he seeks a 15th win on the European Tour. Casey made four birdies in his first seven holes at Emirates Golf Club before finishing birdie-eagle for the low round of the day that lifted him above Scotland's Robert MacIntyre (67) onto 15 under par overall.
