he moved up from eighth to fourth place; Alonso continued his hard charge, gaining four positions as well. However, Trulli's Toyota slowly began dropping back, getting passed again and again; it would later turn out to be a blistered rear tyre, which would affect him for the remainder of the race. Teammate Ralf Schumacher had a problem of his own, and was forced to pit twice in quick succession to tighten a loose safety harness. Räikkönen was able to get by the elder Schumacher into tenth (his starting grid position) and pull away from the champion in pursuit of Heidfeld. After Michael Schumacher's second stop, he emerged from the pitlane just ahead of Heidfeld, who thought he saw an opening going into the third turn. Schumacher, who momentarily lost sight of Heidfeld's Williams in his mirrors, closed the door on his fellow German, forcing him onto the grass. With no traction on the grass, Heidfeld braked in vain, sliding into the side of the F2004M, pushing both cars into the gravel. Heidfeld's race was finished; although Schumacher was able to get his Ferrari back on track, nevertheless he retired in the pits soon thereafter, due to collision damage. Montoya went onto the grass briefly at Turn Eight as he prepared to make his second pit stop; this, plus another off-track excursion while tangling with a backmarking rookie, cost him valuable time. When he later lost part of his rear deflector, Montoya eased up to finish the race and to preserve his Mercedes-Benz power plant for the next race. Teammate Räikkönen also lost a significant portion of his deflector, which became embedded under his side barge board; mechanics were later seen removing it during a pit stop. After the second round of stops, the final order of finish was nearly determined. While most of the field slowed to conserve their engines, Alonso continued pushing hard on Barrichello's heels. Barrichello, despite battling a brake balance problem, was able to answer the challenge, and held off Alonso for second. Fisichella, who flawlessly managed the gap to his nearest opponent all race long, easily took the chequered flag for his second career victory, with his only other victory being for Jordan in . He never put a foot wrong, and his R25 chassis, although not seriously challenged, performed flawlessly to claim the inaugural race of the season. Teammate Alonso clocked the fastest lap of
