We show that hadron production in relativistic heavy-ion collisions at transverse momenta larger than 2 GeV/ c can be explained by the competition of two different hadronization mechanisms. Above 5 GeV/ c hadron production can be described by fragmentation of partons that are created perturbatively. Below 5 GeV/ c recombination of partons from the dense and hot fireball dominates. This can explain some of the surprising features of RHIC data such as the constant baryon-to-meson ratio of about one and the small nuclear suppression for baryons between 2 to 4 GeV/ c .
