We investigate the resummation of large logarithmic perturbative corrections to the partonic cross sections for single-inclusive high-pT hadron production in collisions of transversely polarized hadrons. We perform the resummation to next-to-leading logarithmic accuracy. Phenomenological results are given for ppbar collisions at center-of-mass energy 14,5 GeV and for pp collisions at 62,4 GeV and 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_TT.
