Legendary trainer Bob Baffert says American Pharoah is old news ... telling TMZ Sports his new horse, Justify, is a "superior" animal to the 2015 Triple Crown winner.
Seriously!!
Justify DOMINATED ... winning the Kentucky Derby, making some people think Pharoah might have company as a TC winner pretty soon.
We got Baffert at LAX earlier this week, and he told our camera guy the Triple Crown winner isn't in Justify's company at all, because Baffert -- who trained both horses -- thinks Justify is better.
