The Bass Pro Shops/MBNA 500

As the crisp cool Georgia weather continued to drop throughout the weekend, the Mark checking on another blown engine

"This one hurts, it's really a big blow," said Roush Racing's Mark Martin moments after mechanical failure forced him to retire his No. 6 Viagra® (sildenafil citrate) to the garage after only 133 laps in Sunday's Bass Pro Shops MBNA 500 at the Atlanta Motor Speedway.

"The car was really working good," added Mark. "We were really rolling out there today, but there is nothing we can do about it now."

Indeed Mark and the No. 6 Viagra® Racing team were rolling on Sunday. Mark, who started the race 29th, had patiently moved his way to the front of the field. Mark was running in 12th place and on the move when his day ended on lap 133.

Mark wasted no time when the green flag dropped in Sunday's race, breaking inside the top-20 on lap 41. Mark had moved into 15th place by lap 56 when the team came in for its first pit stop of the day, a green flag stop that saw the team take four tires, fuel and make air pressure adjustments in an attempt to give the 'loose' car more grip in the corners. After a stop of 15.76 seconds, the team returned to the field in 18th place once all the cars had cycled through.

By lap 85 Mark had moved back into 15th place; ready to make a move to the front. Mark moved to 13th place on lap 94 and into 11th place on lap 113. The field began to green flag pit again on lap 114 and Mark came into the pits for the second time of the day, running in fourth place on lap 119.

The team took four tires, fuel and made wedge adjustments in 15.18 seconds and returned to the field in 13th place on lap 120. Mark moved into 12th place on lap 124 and was beginning to run times as good or better than the leaders when his day came to an early end on lap 133.

"It's really unfortunate that we had to go out that way," said crew chief Ben Leslie. "Everybody had worked really hard and we had a good car today, but you just can't worry about things that you can't control. We'll come back next week and do it again. Hopefully we'll get a better result, but I'm still proud of the effort the guys and Mark gave today." The finish dropped Mark to 25th in Winston Cup points standings.Mark and the Viagra® (sildenafil citrate) Racing Team will return to action next week in Darlington.
