This Sunday, 43 NASCAR drivers will have to do something most of them aren\u2019t used to: make a right turn. They\u2019ll be at Watkins Glen for the second of just two road races on the Sprint Cup circuit, the\u00a0Heluva Good! Sour Cream Dips at The Glen<\/strong><\/a>. <\/p>\n That means the NASCAR odds are skewed toward those drivers who have experience in IRL\/Champ Car, Formula 1, and anywhere else with winding courses.<\/p>\n Step right up, Marcos Ambrose. The Australian native has won two races on the Nationwide Series since joining the circuit in 2007 \u2013 both at Watkins Glen. Ambrose is the 7-2 favorite to earn his maiden Sprint Cup victory; he finished third in 2008 driving the No. 21 Wood Brothers Ford, then improved to second last year in the No. 47 JTG-Daugherty Toyota, which he\u2019ll pilot on Sunday.<\/p>\n Ambrose is pretty chalky for someone without a Cup win under his belt, but he definitely has the right background. The 33-year-old got his start in go-kart racing before making the leap to Formula Ford in 1996. Ambrose spent a couple of years in Formula Three, then went on to dominate the Australian V8 Supercar series in 2003 and 2004. He was No. 3 in the 2006 Craftsman Truck Series Rookie of the Year standings and No. 2 to David Ragan on the Nationwide Series the following year.<\/p>\n Coming up in Ambrose\u2019s rearview mirror is Tony Stewart, the second favorite on the NASCAR betting market at 4-1. Stewart has yet to win any races this year after taking the checkered flag four times in 2009, including his fifth victory at Watkins Glen in 11 attempts. Yes, five out of 11. But why is Stewart second to Ambrose on the odds list? Personality might have something to do with it. Ambrose is one of the most congenial drivers on the circuit, gaining in popularity by the second. The outspoken Stewart, meanwhile, was once called the \u201cRosie O\u2019Donnell of NASCAR\u201d by four-time Cup champion Jeff Gordon.
