Green flag racing returned at the 20-hour, 11-minute mark after an extended caution, but didn’t last long as steady rain continues to fall at the Rolex 24.
The top two cars in GTLM were involved in a multi-car incident in Turn 1. Joey Hand was leading in the No. 66 Ford GT, and spun after contact with the No. 911 Porsche of Frederic Makowiecki, who also spun.
“I got totally smoked from behind by a Porsche,” said Hand, who returned after losing nine laps. “Then I hit another car… and another car… and another car.”
Among the other cars that went off were the fourth-place DPi of Romain Dumas in the No. 54 CORE Nissan, the No. 63 Ferrari of Dominik Farnbacher, third in GTD. The No. 11 Grasser Lamborghini of Mirko Bortolotti was running second in GTD, and was tagged twice from behind.
Race leader Jordan Taylor had a close call when Spencer Pumpelly spun the No. 44 Magnus Lamborghini directly in front of him in Turn 1. Taylor took evasive action after barely avoiding the Lambo.
Pipo Derani entered the hour with the lead and managed to hold off the lapped No. 5 Cadillac of Christian Fittipaldi and Taylor. Derani then pitted after an extended stint, with Taylor going to the lead, followed by Alexander Rossi in the No. 7 Acura.
Caution returned at 20:24, when Marco Seefried went off and got stuck in the grass while running second in GTD in the No. 540 Black Swan Porsche.
The race went back to green at 20:44. Kris Wright got turned around facing traffic in the International Horseshoe shortly after the restart. Jack Hawksworth took evasive action in the No. 14 Lexus, but lost seven places after running third in GTD.
There was a lead change in GTD as A.J. Allmendinger pitted and turned the No. 86 Meyer Shank Acura over to Trent Hindman. The promoted Jeff Segal to the lead in the No. 12 Lexus. The second Acura with its all-female driving crew was also those caught out by the conditions, as Katherine Legge spun and was forced to pit with front-end damage.
The No. 540 Porsche — now driven by Dirk Werner — was turned around and stopped in Turn 6, bringing out another caution at 20:51.
At the end of 21 hours — with the race about to go back to green — Jordan Taylor’s No. 10 Cadillac led the No. 31 Cadillac of Felipe Nasr; the No. 81 Nicolas Lapierre led LMP2; the No. 62 Ferrari James Calado led GTLM; and the No. 12 Lexus of Jeff Segal led GTD.
