If Tiger plays the same conservative game he did today, I think more putts will drop for him early and he'll go mid-60s, maybe end up -12. Of course, I have no concept of how those courses play, and how much difference a slight change in conditions will make. So I base my guesses on what I saw today. He's playing early, so that could mean very little wind to contend with. I'd also expect Furyk, Jimenez, Els to shoot low again, maybe Sergio can maintain for another day. Don't know enough about McDowell to say whether he can put together 2 great rounds in a row.

So, leader will be at least -10, with a handful of guys within 2 strokes, and another wad just 3-4 back.

What's the cut going to be? -3?
