Eric Curran and Dane Cameron (No. 31 Action Express Racing Whelen Engineering/Team Fox Corvette DP) captured their first IMSA WeatherTech SportsCar Championship victory of the season Sunday in the Mobil 1 SportsCar Grand Prix at Canadian Tire Motorsport Park, leading Action Express Racing to its second consecutive 1-2 finish. The pair led 66 of the 125 laps in the two-hour and 40-minute race, including the final 36 circuits. Joao Barbosa (No. 5 Action Express Racing Mustang Sampling Corvette DP, started by Christian Fittipaldi) passed Jordan Taylor (No. 10 Konica Minolta Corvette DP, started by Ricky Taylor) for second place in traffic with five minutes remaining. Three minutes later, the third caution period of the race froze the field with Cameron leading his teammate by 17.067 seconds. Curran and Cameron trimmed the points lead of Fittipaldi and Barbosa to four, 220-116, with three races remaining for the Prototype class. The Taylor brothers finished third and are third in the standings with 211 points.
Richard Westbrook and Ryan Briscoe (No. 67 Ford Chip Ganassi Racing Ford GT) delivered their third consecutive IMSA WeatherTech SportsCar Championship GT Le Mans class victory at the track formerly known as Mosport. A strategic call by the Chip Ganassi Racing team sealed the deal for the duo. After running most of the first half of the race in third or fourth place, the team put fresh Michelin tires on for the final time when they pitted under full-course caution an hour and 20 minutes into the two-hour and 40-minute race. The No. 67 Ford GT was sixth in class following that stop, but as the cars running ahead of them made their final pit stops for fuel and tires under green-flag conditions, Briscoe gradually worked his way to the class lead. Then, with approximately 50 minutes remaining in the race, the Ganassi team brought Briscoe on to pit road for a seven-second splash of fuel only and sent him back on course without losing the lead. That was the difference, as Briscoe maintained a 5-6-second gap to Tommy Milner (No. 4 Corvette Racing Chevrolet Corvette C7.R, started by Oliver Gavin) for the remaining distance and the win. “We were in tire and fuel conservation mode as soon as we left the pits, but needed some help,” Briscoe said. “When everyone else pitted we knew we had the opportunity to take a splash of fuel but not change tires. It was a brilliant call by the team. Tommy was a bit quicker, but I was just trying to hang on and bring it home.” Westbrook and Briscoe now trail Milner and Gavin in the GTLM class standings by five points, 192-187. Gavin and Milner finished second, while their teammates Antonio Garcia and Jan Magnussen (No. 3 Corvette Racing Chevrolet Corvette C7.R) finished third. Garcia started the race from the pole and led throughout his 42-minute opening stint, while Magnussen also led for more than 50 minutes.
