Scott Dixon was quickest in the final practice session at Watkins Glen International on Saturday, with the New Zealander edging out Alexander Rossi by just 0.0220 seconds.
Dixon, currently sitting second in championship standings with just this weekends race and the finale at Sonoma Raceway to go this season, set a best lap of 1:22.6441 seconds to edge out Rossi, with the Chip Ganassi Racing and Andretti Herta Autosport drivers the only ones to get beneath the 1:23s barrier.
Ryan Hunter-Reay was third fastest for Andretti Autosport ahead of the leading Team Penske entry of Helio Castroneves, while Sebastien Bourdais completed the top five for Dale Coyne Racing as he continued his progress since returning to the Verizon IndyCar Series following injury last weekend.
Bourdais did end the session with a spin, but his best lap saw him edge ahead of Andretti Autosport’s Takuma Sato in sixth, while Graham Rahal was seventh quickest for Rahal Letterman Lanigan Racing.
Josef Newgarden and Simon Pagenaud, at loggerheads following their banging of wheels during last weekends race at Gateway Motorsports Park, were eighth and ninth respectively for Team Penske, while Charlie Kimball ended tenth for Chip Ganassi Racing ahead of Conor Daly and Tony Kanaan.
The fourth Penske of Will Power struggled to sixteenth, while Jack Harvey, making his first IndyCar road course start this weekend, was nineteenth for Schmidt Peterson Motorsports, just two places behind team-mate James Hinchcliffe.
