Saturday's $750,000 Santa Anita Derby (G1) looks to be a formality on paper, but the race still has to be run, much like a basketball tournament must be played to see who the winner actually is.na can have something up his sleeve at any time, as last year's Belmont S. (G1) proved. CHEROKEE KIM (Cherokee Colony) is only a maiden winner on the turf and would be a surprise of stratospheric proportions were he to win this. <P>
