We prove that a toric polarized manifold is uniformly K-stable in the toric sense if and only if the K-energy functional is coercive modulo the torus action. Our key ingredient describes slope of the reduced J-functional along a torus-equivariant test configuration. It further provides a formulation for general polarized manifolds. We explain how in this situation the sub-torus, actually the center, controls the whole automorphism group.
