Joao Barbosa leapfrogged three competitors shortly before the end of the 18th hour of the Rolex 24 due to quick work by his Action Express pit crew. That enabled the No. 5 Mustang Sampling Corvette DP co-driven by Christian Fittipaldi and Sebastien Bourdais to win the five points for leading the Tequila Patrón North American Endurance Cup at the 18-hour mark.
Jordan Taylor was running second to earn four points for the No. 10 Konica Minolta Corvette DP co-driven by Ricky Taylor and Max Angelelli. That gave the team 11 points, moving them into a tie with the No. 02 Target Ford EcoBoost/Riley driven by Jamie McMurray, Kyle Larson, Tony Kanaan and Scott Dixon with six hours remaining. Third, with 10 points, was Chip Ganassi Racing with Felix Sabates No. 01 entry of Scott Pruett, Joey Hand, Charlie Kimball and Sage Karam.
Points in the four-race Patrón Endurance Cup are awarded at specific intervals throughout each race – every six hours in the Rolex 24 – with the leader at the end of each segment scoring five points, four points for second, three points for third and fourth place on back receiving two points.
Corvette Racing’s pair of Corvette C7.Rs ran 1-2 in the GT Le Mans (GTLM) class for the third consecutive segment. Oliver Gavin led the second straight period in the No. 4 entry co-driven by Tommy Milner and Simon Pagenaud to take a one-point lead over the No. 3 driven by Jan Magnussen, Antonio Garcia and Ryan Briscoe, 14-13.
CORE autosport remained perfect in a bid for a second consecutive Patrón Endurance Cup title in Prototype Challenge (PC), with Colin Braun at the wheel of the No. 54 Composite Resources/Flex-Box ORECA FLM09 he shares with Jon Bennett, James Gue and Mark Wilkins. Braun survived a second cut tire to retain the lead and earn the maximum 15 points through three scoring segments. That opens a five-point lead over the No. 52 PR1/Mathiasen Motorsports ORECA FLM09 of Mike Guasch, Andrew Novich, Andrew Palmer and Tom Kimber-Smith, which ran second for the second consecutive segment.
The opening segment leader in the GT Daytona (GTD) class won the third segment to regain the class lead. The No. 93 Riley Motorsports Dodge Viper SRT GT3-R driven by Kuno Wittmer, Cameron Lawrence, Dominik Farnbacher and Al Carter now has 14 points, one more than the second-segment leading No. 63 Scuderia Corsa Ferrari 458 of Bill Sweedler, Townsend Bell, Jeff Segal and Anthony Lazzaro.
