Identified \ensuremathπ^+/\ensuremath-, K^+/\ensuremath-, p, and p transverse momentum spectra at midrapidity in √sNN\phantom\rule0ex0ex=\phantom\rule0ex0ex130\phantom\rule0ex0exGeV\phantom\rule0ex0exAu+Au collisions were measured by the PHENIX experiment at RHIC as a function of collision centrality. Average transverse momenta increase with the number of participating nucleons in a similar way for all particle species. Within errors, all midrapidity particle yields per participant are found to be increasing with the number of participating nucleons. There is an indication that K^+/\ensuremath-, p, and p yields per participant increase faster than the \ensuremathπ^+/\ensuremath- yields. In central collisions at high transverse momenta (pT\ensuremath\gtrsim2GeV/c), p and p yields are comparable to the \ensuremathπ^+/\ensuremath- yields.
