The RM-Z450-mounted Makita Suzuki rider reeled in race leader James Stewart after gating in fifth place and passed him on the 18th of 20 laps when the Kawasaki rider fell.

Carmichael now holds a four-point advantage in the Amp�d Mobile Supercross series over Chad Reed and trails Stewart by just one point in the World Series after five rounds.

He said: �It�s always good to win but I would have preferred to have beaten James fair and square rather than take the win because he crashed. I�m more excited about how fun and exciting the race was � that is what we need.

�I had a couple of opportunities to pass James but made a couple of mistakes and left it pretty late � when he went down, I thought we were only 10 laps in, not 18��

Carmichael�s team mate Ivan Tedesco raced to fourth place after holding an early lead on the opening lap.
