TRG The Racers Group’s Spencer Pumpelly won Sunday afternoon’s Pirelli GT4 America Sprint series race at Canadian Tire Motorsport Park, the second win for Porsche 718 Cayman CS MR driver in 2019.
The 50-minute, 35-lap contest was exciting from start to finish, with lead changes as early as the first lap: Saturday’s race winner and second-on-the-grid Nicolai Elghanayan in the No. 71 Marco Polo Motorsports KTM X-bow got the jump on pole-sitter Pumpelly to take the lead through Turn 1; but Pumpelly returned the favor through Turns 9 and 10, only to relinquish the lead once again on lap 2 through Turn 3.
But before lap 2 could be completed, Pumpelly re-passed for the lead, and both Gar Robinson (No. 74 Robinson Racing Chevrolet Camaro GT4) and Ian James (No. 50 Team Panoz Racing Panoz Avezzano GT4) moved past Elghanayan who was suddenly struggling.
Back in the Am division, meanwhile, Jarett Andretti’s No. 18 Andretti Autosport McLaren 570S GT4 held the class lead, up to fifth overall and charging through the field, all the way up to second overall on lap 14.
The top five approaching the halfway point were Pumpelly, Andretti, Robinson, Michael Cooper (No. 10 Blackdog Speed Shop McLaren 570S GT4, up from eighth) and James.
Three-time series champion Cooper was on a roll and, on lap 20, he moved past Robinson to slot into third. Two laps later, James pushed past Robinson as well through Turns 3 to slot into fourthth.
By lap 25, Andretti had closed right up to Pumpelly, the gap just .325 seconds. On lap 27, the McLaren and Porsche were side by side through Turn 8, but Pumpelly defended and kept his lead.
With under 10 minutes remaining, Andretti, Cooper and James were in a three-way battle for second, which allowed Pumpelly to gap the trio behind. At the checkered, Pumpelly crossed the line in first by 1.4 seconds, with Cooper second, James third, Stacy fourth and Andretti fallen to fifth, first in the Am class.
With the win, Pumpelly provisionally leads the Pirelli GT4 America Sprint series driver’s championship with 98 points, while James has 93 and Cooper 90 – a close rivalry at the top.
