Kenny Perry and Tiger Woods have just begun their final rounds at the Tour Championship, separated by two strokes and with quite a lot on the line. Perry, who leads by two at 8 under par, is a pretty good closer, going on t win 10 of the 18 times he's taken a lead into the final round. The most recent occurrence caused Perry the most heartache; he's was the 54-hole co-leader at the Masters this year, and led by two strokes with two holes to play. Two closing bogeys followed, and Perry lost a playoff with Angel Cabrera.

Woods won't be fazed by a two-shot deficit. He's won 20 times on the PGA Tour when trailing going into the final round.

The Tour Championship winner will collect $1.35 million, and the winner of the FedEx Cup gets $10 million. A tournament victory would automatically make Woods the FedEx Cup champion. For Perry to win the $10 million, he'll need to win the Tour Championship, and have Woods finish no better than a tie for third.
