Lyle and Beem call it quits early

It seems that the morning conditions at Birkdale got the best of Sandy Lyle and Rich Beem.  Both players withdrew soon after making the turn.  Lyle was at 11-over and Beem was at 12-over. 

According to a Canadian Press story, Beem said after leaving the course:

I'm fine.  I've played a lot of golf and I'm fried. If I had continued, I don't think I would have broken 90. I said very gracefully to the guys on the ninth green, 'I'm sorry, but I can't continue.' It was ugly.

Even with the elements, you'd figure after making the long trek over to Birkdale--especially after going through qualifying--Beem would want to at least finish his round.
