The weather is supposed to be very un-British Open like from what I've heard. Highs in the 70's and not alot of wind. If that holds up, we should see some good scoring with maybe 15-20 guys within 5 shots of the leader going into Sunday.
You have to figure Monty, Els, Singh, Mickelson and Woods will be in the mix. But this tournament, along with the PGA Championship, are the two most likely for someone to win their first major. So guys like Furyk, A. Scott, Luke Donald or Padraig Harrington are right up there as well.
