Scott Dixon was fastest in final practice around the Mid-Ohio Sports Car Course on Saturday morning as Chevrolet-power once again dominated.
The top six in the session were all powered by Chevrolet, with multiple series champion Dixon setting a best time of 1:03.7244 for Chip Ganassi Racing, 0.1694 seconds faster than current championship leader Simon Pagenaud, who was just ahead of his main title rival and Team Penske team-mate Will Power.
Josef Newgarden was fourth fastest for Ed Carpenter Racing ahead of Chip Ganassi Racing duo Tony Kanaan and Max Chilton.
Graham Rahal was the best placed of the Honda-powered racers, with the Rahal Letterman Lanigan Racing driver finishing seventh, 0.3520 seconds down on the pace, while Charlie Kimball made it all four of the Ganassi entries inside the top eight.
James Hinchcliffe ended the session ninth for Schmidt Peterson Motorsport, while Ryan Hunter-Reay was the only Andretti Autosport driver to make it inside the top sixteen runners, with the former series champion ending tenth fastest.
There were two red flag periods during the session, the first of which was caused by Spencer Pigot spinning backwards into the turn four gravel, while Conor Daly ended the session early after also having an off.
