Cadillacs were running 1-2 as the Rolex 24 At Daytona heads into the ninth hour, Alex Lynn taking the lead in the No. 02 Chip Ganassi Racing V-LMDh from Pipo Derani in the No. 31 Action Express Racing car toward the end of the hour. It was the 19th lead change in the race.
The No. 31 has reportedly lost telemetry, however, meaning the drivers will have to verbally report energy usage back to the pit stand.

Brendon Hartley ran third in the No. 10 Wayne Taylor Racing Acura, with Nick Tandy fourth in the No. 6 Porsche.
The racing has been hard-fought and traffic has continued to play a part, Hartley putting two wheels on the grass at one point while passing lapped cars.

The GTD PRO leaders are beginning to flock together.
Heart of Racing remains out front with David Pittard still driving the No. 23, but Jack Hawksworth in the No. 14 Vasser Sullivan Lexus RC F is beginning to apply pressure.
