The final practice period for Sunday’s Grand Prix of Portland went from good to bad for Sebastien Bourdais in the flick of the steering wheel on Saturday morning at Portland International Raceway.
After turning the fastest lap of the 45-minute session, Bourdais lost control of his SealFast Honda at Turn 11 and slammed backward into the tire barrier. The gearbox was badly damaged and Dale Coyne’s team was scrambling to get the car ready for qualifying in three hours.
Bourdais ran a lap of 57.4707 seconds the lap before — just edging Graham Rahal’s best of 57.5142s in the RLL Honda and Will Power’s 57.5508 in the Verizon Chevy.
Alexander Rossi, who trails Scott Dixon by 26 points with two races remaining in the IndyCar season, turned in the fourth-fastest lap of 57.6229s in the NAPA Honda and Takuma Sato rounded out the top five at 57.6760s in the MiJack Honda.
UP NEXT: Qualifying at 6:20pm ET.
