Jnathan Bomarito won his first IMSA WeatherTech SportsCar Championship pole position since 2014 on Saturday at Road America.
In qualifying for the 2-hour, 40-minute race Sunday, Bomarito had a fast lap of 127.2 mph in the No. 55 Mazda Prototype to lead the 41-car field.
It was Bomarito's first pole in the IMSA Prototype class and his first IMSA pole of any kind since taking the top spot in the GT Le Mans class at Circuit of The Americas in 2014.
He and co-driver Tristan Nunez head into the looking for their first IMSA victory. Nunez has qualified on the pole position twice earlier this season.
"It's been a lot of work to get to this point, but tomorrow is what it's all about," Bomarito said. "It's going to be a hard fight. It's tough like always, we're just going to do our thing, get a good start and kind of manage from there. Hopefully it goes as well as the rest of the weekend."
Christian Fittipaldi will start second in the No. 5 Action Express Racing Corvette Daytona Prototype, following a lap at 125.9. Dirk Muller — the GTE Pro class winner in June in the 24 Hours of Le Mans — will start from the GT Le Mans class pole position in the Ford Chip Ganassi Racing Ford GT.
Other class pole winners were James French in the No. 38 Performance Tech Motorsports ORECA in the Prototype Challenge class, and Alex Riberas in the GT Daytona class driving the No. 23 Alex Job Racing/Team Seattle Porsche.
