We set up a formalism for calculating the [ital O]([alpha][sub [ital s]]) corrections to the process [ital p[bar p]][r arrow][ital W][sup +][ital X][r arrow][bar [tau]][nu][sub [tau]][ital X] with spin-correlated [tau] decays to leptons and mesons. Our results are applicable to Monte Carlo integration, which allows easy construction of any desired observable at next-to-leading-log level, and the possibility to include experimental cuts. Our results are applied explicitly to the decay modes [tau][r arrow][bar [nu]][sub [tau]][ital [bar e]][nu][sub [ital e]], [bar [tau]][r arrow][bar [nu]][sub [tau]][pi][sup +], and [bar [tau]][r arrow][bar [nu]][sub [tau]][pi][sup +][pi][sup 0]; other decay modes may be included in a straightforward fashion. We show results for transverse momentum and rapidity variables in leading-log and next-to-leading-log approximations; the leptonic observables are compared to similar observables from direct [ital W][r arrow][ital [bar e]][nu][sub [ital e]].
