  We present results on identified particle production in p+p, d+Au and Au+Au
collisions at $\sqrt{s_{NN}} = 200$ GeV at mid-rapidity measured by the PHENIX
experiment. The centrality and flavor dependence of the Cronin effect in d+Au
collisions is measured. The Cronin effect for the protons in d+Au is larger
than that for the pions, but not large enough to account for the ``anomalous''
proton to pion ratio in central Au+Au collisions.
