In his rookie year of MotoGP, Hayden would be overshadowed by his teammate Valentino Rossi, who was the defending series champion of the year, but would still score consistent points. At the opening round in Japan, Hayden finished seventh while Rossi won the race. But the race was marred by the death of Japanese rider Daijiro Kato who crashed at the 130R and hit the barrier at high speed in the ensuing Casio Triangle. At the next race in South Africa, Hayden would once more finish in seventh position while his teammate scored second place.
