Spencer Pumpelly broke Michael Cooper’s six-race win streak in Pirelli GT4 America Sprint competition by taking victory in Saturday’s round.
While having started on pole, Cooper dashed around the No. 66 TRG Porsche 718 Cayman GT4 Clubsport at the start and held a narrow lead over Pumpelly for the majority of the 50-minute contest.
However, in a brave move, Pumpelly got around Cooper’s No. 10 Blackdog Speed Shop McLaren 570S GT4 in Turn 5 with 14 minutes to go and held off a strong final lap charge by the McLaren Automotive factory driver.
Pumpelly crossed the line 0.204 seconds ahead of Cooper to claim his first win since Race 1 at Virginia International Raceway.
Michael Dinan completed the overall podium again in his Flying Lizard Motorsports Aston Martin Vantage GT4, which was good enough to pick up Am class honors.
Dinan’s closest challenger, the No. 59 Rearden Racing Aston of Paul Terry, spun out of fourth place at the halfway mark of the race.
It promoted the No. 11 Blackdog McLaren of Tony Gaples to a second place class finish and fifth overall.
Three of the 15 starters from Friday’s race did not take the green flag, with Mark Klenin, Ray Mason and Jef Burton all having sustained crash damage in Race 1.
RESULTS: Race 2
Dinan Makes Late-Race Pass for SprintX Win
Michael Dinan and Robby Foley claimed victory on Saturday, denying BimmerWorld top honors thanks to a last-lap pass.
Dinan made a late-race charge in his No. 21 Flying Lizard Motorsports Aston Martin Vantage GT4 to get around the No. 82 BMW M4 GT4 of James Walker Jr. for the lead on the outside of Turn 1.
The car came from 15th overall on the grid to take a 2.938-second win over Walker Jr. and Bill Auberlen, who dominated the first half of the 60-minute contest.
It marked Dinan and Foley’s second overall victory in the last three races and came after a retirement in Friday’s round.
The No. 71 MarcoPolo Motorsports KTM X-Bow GT4 of Mads Siljehaug and Nicolai Elghanayan finished third overall, picking up GT4 Silver class honors in an equally enthralling late-race battle.
Siljehaug got around the No. 36 Andretti Autosport McLaren 570S GT4 of Colin Mullan for the position with three minutes remaining, demoting Mullan and Jarett Andretti to fourth and second in class.
Bryan Putt, who took over the No. 15 Bsport Aston Martin GT4 in second after a strong opening stint by Kenton Koch, completed the top-five overall.
John Allen, meanwhile, held on to claim GT4 Am class honors in the No. 16 Rearden Racing Mercedes-AMG GT4, just a half-second ahead of a hard-charging Sean Gibbons, who won Race 1.
The third and final SprintX race of the weekend is on tap for Sunday at 10:30 a.m. CT.
