The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory delivers the world highest energy polarized proton-proton collisions at a center of mass energy up to 500GeV and provides a unique opportunity to study the spin structure of the proton at high-energy scale. In recent years, there has been tremendous experimental and theoretical progress toward understanding the physics with transversely polarized beams (or targets). The scope of research in transverse physics involves from measurements of nucleon structure and parton distribution functions to the studies of QCD dynamics in high-energy polarized DIS and p+p collisions.During the 2006 and 2008 RHIC runs, the PHENIX experiment took a significant amount of transversely polarized p+p collision data at the center of mass energies of 62 and 200 GeV, with integrated luminosity of 8 pb-1 at 200GeV and beam polarization of 45%(run8) and 57%(run6). In this report, I highlight the latest results from the PHENIX experiment, followed by a brief discussion of the future prospects of transverse physics with the PHENIX upgrade detectors, particularly on the importance of the unique measurements of open charm, J/Psi and Drell-Yan productions.
