2011 Open Leaderboard Taking Shape; Final Round Thoughts?

It's hard not to like Darren Clarke no matter how poor the putting is if he keeps striking the ball the way he did Saturday. Throw in the difficulty of making putts and there just doesn't feel like a 64 is out there.

But this is Royal St. George's and even with what we've seen the first two days, I'm finding it difficult to rule anyone out within six shots of the lead. Thoughts?
