INDIANAPOLIS -- Jimmie Johnson was the halfway leader in his quest to win a record fifth NASCAR Brickyard 400 on Sunday.
Johnson led 43 of the first 80 laps of the 160-lap race on an unseasonably cool day at Indianapolis Motor Speedway. The temperature was 68 degrees when the race started.
Dale Earnhardt Jr., who started 15th, found trouble early when he had a loose tire on his No. 88 Chevrolet and was forced to pit after only 12 laps.
But Earnhardt caught a break when the caution flag appeared on Lap 59, enabling him to get back on the same lap as the leaders. He was running 13th.
Danica Patrick was running 32nd in the 43-car field, one lap down to the leaders.
