if it ended right now, tiger would have 3 wins to Rory's 2, he would have won the FedEx cup and the money title. they each missed 3 cuts this year with one of Rory's in a major. Rory has an extra top-10 but Tiger edges him in scoring average. and they each only have 1 top 10 in a major. that's practically a dead-heat, but with Tiger "winning" the FedEx cup, the money title, and the scoring title, i think that pushes him past Rory.
however, with all of that said, their stats are so close, it could all change in one week.
