Jamie McMurray wins first Nationwide race in six yearsNick BrombergSeptember 5, 2010>Maybe Saturday night will be the boost that Jamie McMurray needs to catch Clint Bowyer.McMurray won Saturday night's Nationwide race at Atlanta, pulling away from Kyle Busch after a late race restart. It was the first Nationwide win since 2004 for McMurray, who was in the No. 88 for JR Motorsports.McMurray enters Sunday's Sprint Cup Series race 100 points behind Bowyer in the chase for the final Chase spot.Kevin Harvick looked like he had the car to beat in the midpoint of the race after pitting off sequence from the rest of the field. The fresh tires gave Harvick a 12 second lead at one point, but once the rest of the leaders started pitting, Harvick stayed out too long on older tires. He exited the pits eight seconds back in fourth and never regained the lead.Series points leader Brad Keselowski stayed out to try to catch another quick caution on the last restart, and the decision to start on old tires proved costly as Keselowski ended up 12th.
