Bourdais, who has won on this track in IndyCar, lapped the 2.35-mile 14-turn course in 1min19.307sec to outpace Ricky Taylor in the Wayne Taylor Racing Acura ARX-05 by just over two-tenths of a second.
Alex Lynn, despite encountering the fiendishly bumpy course for the first time this week, was barely more than a quarter-second from Bourdais to ensure both Ganassi entries were in the top three. Tom Blomqvist was similarly impressive and for the same reason, as his Meyer Shank Racing Acura lapped the course just a tenth slower than the WTR Acura.
