Watch: Rory McIlroy takes tournament lead after opening 63 at WGC Mexico Championship
Rory McIlroy has made a blistering start to his bid for glory at the WGC Mexico Championship.
The world number eight carded an eight under par 63 to set the pace in Mexico City after hitting 17 greens in regulation.
McIlroy was eight under after his first 13 holes. He picked up four shots on a bogey-free opening nine and his cause was helped by an eagle at the 305 yard par four first - Rory's 10th hole of the day having started on the back nine.
It took only a perfectly faded two iron to set up a six foot birdie putt that Rory rolled in to get his second nine off to the perfect start.
Watch his eagle here:
Further birdies followed at the second and the fourth before a disappointing drop-shot at the par five sixth, after hitting a tree with his second shot, was counteracted by a birdie on the eighth, Rory's 17th hole of the day.
Rory's stunning opening round was enough to secure the outright lead, one ahead of Dustin Johnson, who carded a 64 in the group behind McIlroy.
The round came just hours after news broke of McIlroy's contentious decision not to play in this year's Irish Open as he fixes his sights firmly on the Open Championship at Royal Portrush.
Meanwhile, Graeme McDowell is T20th after a two under par opening round at the Puerto Rico Open. The Portrush man is four behind round one leader Andres Romero.
