We investigate the resummation of large logarithmic perturbative corrections to the partonic cross sections for single-inclusive high-p{sub T} hadron production in collisions of transversely polarized hadrons. We perform the resummation to next-to-leading logarithmic accuracy. Phenomenological results are given for pp collisions at center-of-mass energy {radical}(S)=14.5 GeV and for pp collisions at {radical}(S)=62.4 GeV and at {radical}(S)=10 GeV, which are relevant for possible experiments at the GSI-FAIR, RHIC and J-PARC facilities, respectively. We find significant enhancements of the spin-dependent and spin-averaged cross sections, but a decrease of the double-spin asymmetry A{sub TT}{sup {pi}}.
