The 2002 champ has a 52-point lead over Jimmie Johnson heading into the Ford 400 at Homestead-Miami Speedway, where he has won twice. Carl Edwards, who won two of the last three races to pull within 87 points, knows that doesn't bode well for his hopes of catching Stewart in the 2005 finale. "We probably won't beat Tony Stewart," says Edwards. "Probability would say it probably won't happen." Tough to argue with that logic. NBC 4 p.m.
