Behind Rahal, Ed Carpenter Racing’s Spencer Pigot was second, with a best lap of 1:17.6641. Championship contenders completed the top five, with Chip Ganassi Racing’s Scott Dixon in third and Team Penske drivers Helio Castroneves and Josef Newgarden in fourth and fifth.
Of note, the remaining championship combatants Simon Pagenaud and Will Power were 16th and 19th, respectively.
The session was stopped briefly when Dixon’s teammate Max Chilton spun and stalled exiting Turn 3. However, he did not hit anything and was able to continue on, ending up 12th.
