Australia's Adam Scott and American Jason Dufner produced smart golf to share the lead at six-under after the first round of the WGC-Cadillac Championship Thursday while the big names toiled in windy conditions. Newly-crowned world No. 1 Rory McIlroy struggled to a one-over-par 73, while Tiger Woods, who shot the best final-round of his life last Sunday, ended even-par after mixing four bogeys with three birdies and an eagle on his opening hole. Scott, who tied for second at last year's Masters, made four birdies on the back nine, where he started, before an eagle on the par-five first and a birdie on the second. His only blemish was a bogey on the sixth which allowed Dufner, who finished second at the PGA Championship last year, to grab a share of the lead with a birdie on his last hole, the par-three ninth, for a 66. Denmark's Thomas Bjorn and Masters champion Charl Schwartzel of South Africa were both two shots off the pace after shooting four-under 68s. The top group featured McIlroy and world No. 2 Luke Donald and third-ranked Lee Westwood. While Donald posted a solid two-under 70, Westwood had to grind for a four-over 74. Donald could regain the world No. 1 ranking from McIlroy with a win here while Westwood would also reclaim his crown with a win if the Northern Irishman finished outside the top three. Phil Mickelson finished even-par after starting with bogeys on the 12th and 14th.
