 In the third consecutive race to require a green-white-checker finish, Jimmie Johnson blew past Matt Kenseth on the last corner of the day to get his 20th career victory and second of the season.Kenseth looked like a good bet to cruise to victory before Denny Hamlin and Kenny Wallace wrecked three laps from the end, bunching the field and leading to the overtime finish.Before the lap 268 restart, Kenseth told his crew that his engine felt weak, but he was able to protect the lead until the last corner, where Johnson, who had not led all day, overtook the 17 car on the high side to take the win by a half a car length.
