ATLANTA --- Chad Campbell tipped over a small bucket of balls Wednesday and hit 5-irons across the pond on the practice green at East Lake, none quite as true as the one he struck five days ago at Valhalla that earned a crucial point in the Ryder Cup.

Campbell, the last player to qualify for the 30-man field at the Tour Championship, will understand if his game doesn't arrive until sometime later in the week.

"It's going to take a few days," he said. "I think once the tournament gets going, I'll be good to go. But everybody is a little bit worn out."

Ten Americans who were spraying one another with champagne on Sunday are trying to remind themselves that this, too, is a big week. The Tour Championship features a $7 million purse.

The only two missing at East Lake from the U.S. team are J.B. Holmes and Boo Weekley. Sergio Garcia is the only Ryder Cup player from Europe who qualified.

"It is different," said Hunter Mahan, who went unbeaten in five matches in his Ryder Cup debut. "It's weird going through that and then having to come to such a big event like this."

A new points system for the PGA Tour's playoffs brought the kind of volatility the tour wanted, but it knocked out several players who otherwise would have had a right to be at East Lake.

Padraig Harrington missed the cut in his first two playoff events, and for that he becomes the first PGA Tour member to win two majors in one year and still not qualify. Also missing are Adam Scott, Geoff Ogilvy and Weekley.

As for the drama over who wins the $10 million prize?

Vijay Singh won the first two playoff events, and now he only has to complete four rounds at East Lake to win the FedEx Cup.

"It's been kind of strange in a way that your friends and your family and your trainer keep saying, 'Don't overexercise. We'll have to just keep it nice and easy this week,' " Singh said. "Gets in your head a little bit."
