Mark Martin would have gambled, but it wasn't his call.

Jimmie Johnson won Saturday night's Subway Fresh Fit 500 with a courageous fuel-mileage gamble, squeezing 82 laps out of his last tank of gas.

Clint Bowyer also gambled on fuel mileage, when crew chief Gil Martin kept him on the track while others pitted for two tires and gas or only a splash of gas during the final 15 laps. Bowyer finished second.

Martin's crew chief, Tony Gibson, opted for the conservative strategy, telling the driver of the No. 8 Dale Earnhardt Inc. Chevrolet to pit from the lead with 10 laps left in the 312-lap event. Martin had passed Dale Earnhardt Jr. for the top spot on Lap 272 and had maintained a comfortable edge over his pursuers in the succeeding 30 laps.

Martin had been saving fuel, too. The No. 8 crew had filled up the U.S. Army Chevy under caution on Lap 230, when the lead-lap cars came to the pits for tires and fuel. That pit stop was Martin's next-to-last. Unfortunately for his victory prospects, it was Johnson's last.
