Not really all that surprised, Lee is a far more experienced matchplayer and playing decent golf. I'm not saying Speith isn't an amazing golfer, he is, but he's had one Ryder Cup solo match which he lost to a not-really-in-form G Mac having gone a few up on him early. So pedigree would have suggested Lee was in with a better than average shout.
Looking forward to some cracking last 16 matches, now it really gets interesting!
