I figured it wouldn't take long for a thread like this...
But the guy is fairly highly ranked worldwide, clearly knows how to win on the Euro tour, and took (OK, was given) the lead early on the front nine and held it all the way. Tiger, Phil, Ernie, even Davis Love had plenty of chances in the world but couldn't keep their drives in play, missed greens with short approaches from the fairway, and missed putts (in Tiger's case mostly from being too tentative) Like Miller said, they're probably all kicking themselves realizing how much easier it would have seemed on the first tee if they'd only known that -1 was the score to beat!
Its a pretty quality leaderboard, other than the outlier Havret.
