ELKHART LAKE, Wis. – Michael Cooper completed a weekend sweep of Pirelli GT4 America Sprint competition on Sunday at Road America.

Sunday’s Pirelli GT4 America Sprint race saw the green flag waved under wet and rainy conditions as Saturday’s race winner and championship leader Michael Cooper lead the field to the green flag in his No. 10 Blackdog Speed Shop McLaren 570S GT4.

At the start, Spencer Pumpelly and the No. 66 TRG Porsche 718 Cayman CS MR fell to fourth from second, but quickly moved back into the third position as the field went to turn five. Pumpelly continued his charge past Shane Lewis and the No. 72 Robinson Racing Camaro GT4 at Canada Corner for second and went into pursuit of Cooper for the lead.

While Drew Staveley and the No. 12 Ian Lacy Racing Ford Mustang GT4 pulled away from the rest of the Am field, Alan Brynjolfsson and the No. 7 Park Place Porsche 718 Cayman CS MR got past Tony Gaples in the No. 11 Blackdog Speed Shop McLaren 570S GT4 for second position in class, as the owner/driver continued to fall through the order in the wet conditions, ending up fifth.

With 13 minutes off the clock, Staveley was spun out of the class lead after contact with Jarrett Andretti and the No. 18 Andretti Autosport McLaren 570S GT4 at Canada Corner. Staveley was able to continue but would fall to second place, handing the class lead to Brynjolfsson. A full course caution was called shortly after as rain continued to pound the circuit.

With 23 minutes remaining on the clock, the race was red flagged and would not restart, handing the weekend sweep to Cooper.
