had passed Rodríguez, but by that time, Stewart's lead was nearly twenty seconds. Graham Hill, in a privately entered Lotus 72, came into the pits on lap 30 with fuel leaking into the cockpit, as a fitting had come loose under the seat. The team took 10 minutes to fix the leak, threw some water on Hill, whose overalls were soaked in fuel, and sent him back out. Several laps later, Hill returned to request they find him some dry overalls, as the gasoline was burning his skin. When he stopped again to change clothes, the team said they had not been able to locate any new ones. Hill, however, saw John Surtees, who had retired on the seventh lap, sitting on the wall, and borrowed his overalls and undergarments. The two former World Champions were naked in the pits as Hill was doused with water before donning Surtees' clean clothes and returning to the track, only to retire on lap 72 with a broken clutch. At half-distance, Stewart was nearly half a lap ahead of Ickx, with Rodríguez in third and Fittipaldi about to be lapped in fourth. Ickx suddenly pitted on lap 57 to repair a broken fuel line, and he rejoined in twelfth place. He fought his way back up to fourth, setting the race's fastest lap three laps from the finish. Ickx had needed to win to have a chance of overtaking Jochen Rindt in the Championship; his fourth-place finish meant that Rindt became the first posthumous Formula One World Champion. On lap 76, with a one-minute cushion, Stewart's Tyrrell began trailing smoke from its left-hand exhaust pipe. The smoke slowly grew worse, and Rodríguez tore into Stewart's lead, taking off five seconds a lap, while the Lotus teammates unlapped themselves. On lap 83, with its oil gone, the Cosworth engine in the Tyrrell seized, leaving Rodríguez with an 18.8 second lead over Fittipaldi, who led team-mate Reine Wisell by another 46 seconds. At the end of the 100th lap, Rodríguez coasted into the pit lane having run out of fuel. BRM refueled the car, but Rodríguez had lost 38 seconds to Fittipaldi, who took the lead. Rodríguez rejoined ahead of the second Lotus of Wisell. Fittipaldi recalled later, "I took the lead and, going over the finish line, I saw for the first time Colin [Chapman] jumping and throwing his hat, something I'd seen him
