WATKINS GLEN, N.Y. — Watkins Glen International is a special place for Scott Dixon. He showed why again Sunday.Fastest in every practice and fastest in qualifying, Dixon won the IndyCar Grand Prix at the Glen with a dominant drive, leading all but 10 of the 60 laps around the 11-turn, 3.37-mile natural terrain layout."We've had some dominant wins like this on ovals," Dixon said after his 40th career victory. "But I think to lead all three practices, qualify on the pole, and then win the race, it was definitely a very dominant weekend."Josef Newgarden was second, followed by Helio Castroneves, Conor Daly, and St. Petersburg resident Sebastien Bourdais.New Port Richey's RC Enerson, in his second series race, was ninth.Dixon announced he was donating his winnings to the family of Justin Wilson, who died in August 2015 after being struck in the head by debris during a race at Pocono.Simon Pagenaud finished seventh and increased his lead over Will Power to 43 points with one race left. Power crashed and finished 20th. The two Penske drivers are the only ones who can win the title at the finale, Sept. 18 in Sonoma, Calif., with double points available. Trucks: John Hunter Nemechek bested Cole Custer in a door-to-door drag race through the grass to win the Chevrolet Silverado 250 in Bowmanville, Ontario. As Nemechek climbed from his truck to collect the checkered flag, Custer knocked him to the ground with a leaping tackle. F1: Nico Rosberg won the Italian Grand Prix at Monza virtually unchallenged after Mercedes teammate Lewis Hamilton wasted his pole position with a poor start. Hamilton, the two-time defending world champion, leads Rosberg by two points with seven races left. NHRA: Courtney Force won a $100,000 Funny Car shootout and Matt Hagan topped qualifying at the U.S. Nationals in Indianapolis.
