We report measurements of e+K+, and p, p» inclusive cross sections and fractions in e+e- annihilation at s=29 GeV, for the momentum interval 0.01<z=ppbeam<0.90. The analysis is based on approximately 70 pb-1 of data collected with the TPC2 detector facility at the SLAC storage ring PEP. Detector upgrades result in significantly improved momentum coverage and precision of the data, compared to previous measurements.
