St. Petersburg, Fla. – Jack Roush Jr. won the GTS pole for Friday’s Round 3 race at the Pirelli World Challenge Cadillac Grand Prix of St. Petersburg. The 20-minute qualifying session was held under sunny skies and 80-degree temperatures.

GTS Driver Championship points leader Lawson Aschenbach, in the No. 10 Blackdog Speedshop Chevrolet Camaro Z28, posted the early fast lap with a 1:19.786, followed by Roush Jr., in the No. 60 Roush Performance Ford Mustang Boss 302, with a 1:19.815, and Brett Sandberg, in the No. 13 ANSA Motorsports KTM X-Bow GT4 (1:20.097).

At the 10-minute mark, Roush Jr. then went to the top of the charts with a 1:19.374, followed by Sandberg with a 1:19.398. Roush then set the bar even higher with a 1:19.213, while Aschenbach slotted into second on the charts with a 1:19.251.

Both Roush’s and Aschenbach’s times held as the checkered flew to end the session. For Roush Jr., it’s his second career PWC pole (his first career pole was secured at Long Beach in 2014). Sandberg will start third. Rounding out the top 5 are PWC veteran Charles Espenlaub, in the No. 93 AK&J Sealants Maserati GranTurismo MC (1:20.112) – set to make his 92nd series start and first since 2010 on Friday – and rookie Parker Chase in the No. 19 Performance Motorsports Group Ginetta GT4 (1:20.237).

“The car is really solid here. I think the Mustang is a good car at this track,” said Roush Jr. “It seems very stable over the bumpy road courses. I really have to hand it to my crew (led by Dean Martin). They gave me a really fast car and I’m just the monkey behind the wheel. The car felt great today and I hope we have a good car in the race on Friday. My first pole was at Long Beach in 2014. I haven’t really done a ton of street racing, but more in the last three years. So it’s new to me really. I don’t know why but I really enjoy racing on the street courses.”

Results are provisional until posted final. GTS drivers now get set to race Round 3 on the 14-turn, 1.8-mile temporary Streets of St. Petersburg course scheduled for 12:20 pm eastern on Friday.
