Joao Barbosa and Christian Fittipaldi teamed to win Saturday's Diamond Cellar Classic in the No. 5 Action Express Racing Corvette DP, giving the team its first Rolex Series victory of the season.
Barbosa caught Richard Westbrook and passed him for the lead with less than 30 minutes remaining. Until that point, Westbrook and co-driver Ricky Taylor dominated the event in the No. 90 Spirit of Daytona Corvette DP.
“We've been fast all year, but the results haven't been there. This is where we should be," declared Barbosa. "Today the team did a great job. Our pit stop was awesome, the Corvette was awesome, and Christian drove a great opening stint.”
Westbrook lost second on a spin, with Taylor returning to the race to finish ninth.
Defending race winner Michael Valiante also had a strong race in the No. 3 8Star Motorsports Corvette DP started by Enzo Potolicchio, finishing second, 1.427 seconds back. Max Angelelli and Jordan Taylor finished sixth in the No. 10 Velocity Worldwide Corvette DP, managing to retain a one-point lead over Alex Gurney and Jon Fogarty, with third-place finishers Ryan Dalziel and Alex Popow another point back.
Bill Auberlen and Paul Dalla Lana took their second GT victory of the season in the No. 94 Turner Motorsport BMW M3. Auberlen was pressured down the stretch by Eric Curran, driving the No. 31 Marsh Racing Corvette started by Boris Said. The two made contact with two laps remaining, with Auberlen spinning out of the lead, but Curran was assessed a one-minute, 24-second penalty that dropped him out of the top five. Andy Lally and John Potter took the GT point lead by finishing second in the No. 44 Magnus Racing Porsche.
Sylvain Tremblay and Tom Long took the first victory for the No. 70 SpeedSource Mazda 6, trimming the GX class lead of Dr. Jim Norman and Spencer Pumpelly to 16 points.
