With Adam Scott still holding a four-shot lead going into the final round, only three groups are really within six shots of the lead. While the likes of Luke Donald and Bubba Watson have good tee times for the last round, they are nine and ten shots behind.
Only once in Open Championship history has someone come from that far back and won: Paul Lawrie in 1999.
With that much of a lead, Scott will have to really stumble to be caught from that far back. The general rule of thumb is anyone within five shots of the lead has a chance. They will get the most attention on television and have the biggest crowds.
The times listed are Eastern and the last three groups are:
9:10 a.m. Ernie Els (-5), Zach Johnson (-5)
9:20 a.m. Tiger Woods (-6), Brandt Snedeker (-7)
9:30 a.m. Graeme McDowell (-7), Adam Scott (-11)
If Scott stumbles, or if one of these chasers plays a great round of golf and a playoff is needed, then they will play a four-hole total score mini-round Sunday evening. The sun sets at nearly 9:30 local time, which is about 4:30 in the afternoon on the East coast. There is plenty of daylight to get a full Sunday finish.
More often than not, the eventual winner comes out of the last group, but it is hard to really think, with Scott's lead and the quality of players in the last three groups, that the winner will be anyone different from these six golfers.
