McIlroy triumphed over Miguel Angel Jimenez and will now face the biggest surprise of this week, Sang-moon Bae of Korea, who despatched John Senden and becomes just the third Korean to reach the quarterfinals in this event. LYONS/GETTY IMAGES McIlroy's commented' "Miguel is a veteran and a wily competitor, even with a three-hole lead, it wasn't safe. "I don't think you've seen my best, but there definitely were glimpses of it today." Westwood comfortably beat Nick Watney 3 and 2 and will now face Martin Laird, who got the better of his countryman Paul Lawrie 3 and 1. Lee has stated that being No. 1 in the world is not his top priority, but, "I'd be lying if I didn't say every guy playing this week wants to be No. 1 in the world. It means you're playing well, for starters." Lee got his revenge over the American, Watney, who had knocked him out the previous two years, "I really didn't want to make it a hat trick of wins on his part. I made a lot of birdies today and didn't let Nick get into the match." Mark Wilson eliminated Dustin Johnson for the second straight year, this time 4 and 3. Mark will now face Peter Hanson, who beat Brandt Snedeker 5 and 3. Hunter Mahan was a 4 and 3 winner over Steve Stricker, yesterdays birthday boy.

Matt was happy with his days work, saying, "I played some great golf, Martin's a tough competitor."
