He started the 2001 season in typically strong form; winning 2 of the first 3 main events. However, he lost the next event to Team Kawasaki's Ricky Carmichael. Carmichael would then win every race from there on out; dethroning McGrath as Supercross champion and equalling his 1996 win record of 13 consecutive main event victories. McGrath returned in 2002 to take a shot at regaining his crown, but chronic arm pump (Compartment Syndrome) and perhaps age caught up with him, and he could only muster a 3rd place in the final standings behind Carmichael and Yamaha's David Vuillemin.
