eighth position. By the same lap, Barrichello led by a second over his teammate Michael Schumacher, who in turn was 17 seconds ahead of Ralf Schumacher. Further down the order, Frentzen put a rear wheel on the grass at the final corner on lap 16. He lost control of his car, spun through 180 degrees and rolled backwards in front of the race leaders. Frentzen fell to 18th position, behind the Minardi cars of Webber and Yoong. He passed Yoong to return to 17th position on the 18th lap. One lap later, Villeneuve overtook Salo on the inside for seventh place and blocked Salo's attempted counter-move. As the Ferraris extended their lead over Ralf Schumacher, the stewards informed the BAR team on the 23rd lap Villeneuve had incurred a drive-through penalty as they deemed him at fault for the collision with Frentzen on lap one. Lap 24 saw the safety car's first deployment by the race director: Panis' engine seized without warning on the start/finish straight. His rear wheels locked, spun to the centre of the track and avoided hitting the barrier. Track marshals removed Panis' car from the circuit as he returned to the pit lane. The Ferrari and Williams' teams employed different pit stop strategies—the Ferrari team planned for two stops whereas the Williams team planned one. The Ferrari team called Barrichello and Michael Schumacher into the pit lane for their first pit stops; Schumacher drove more slowly than Barrichello to allow their mechanics to service the latter's car first. Barrichello retained the lead as Michael Schumacher yielded second to Ralf Schumacher. The safety car was withdrawn at the conclusion of the 27th lap and Barrichello led at the restart. Soon after, a major accident prompted the safety car's second deployment on lap 28. As the field entered the right-hand turn two situated atop a hill, Heidfeld noticed smoke coming from Yoong's Minardi and applied his cold brakes heavily, locking his rear wheels and sending him out of control about from the apex. He veered into the grass at approximately as his car spun 180 degrees; the grass did not slow him, and was launched over the crest of a hill. Montoya on the inside was about to lap Sato's slower car at turn two, with the latter ahead at the apex. At high speed, Heidfeld narrowly avoided hitting Montoya's front wing, and the rear of his Sauber
