NASCAR's Sprint Cup Series runs its second and final road course race of the season this weekend in Sunday's Finger Lakes 355 at Watkins Glen International.  Clint Bowyer won the season's first road course event in June at Sonoma.  Marcos Ambrose became a first-time Sprint Cup race winner one year ago when he took the checkered flag at Watkins Glen.  The event was delayed one day due to rain.  Ambrose passed Brad Keselowski for the lead during a green-white-checkered finish and then held it for his maiden victory in his 105th start in NASCAR's top series.  Jeff Gordon won last weekend at Pocono, but Dale Earnhardt Jr. still holds a five-point lead over Matt Kenseth atop the Cup Standings.  Greg Biffle is just six points back in third, while Jimmie Johnson trails Dale Jr. by just eight points to sit in fourth.  Martin Truex Jr. rounds out the top-five.
