Using 3.08×106 ψ(2S) decays observed in e+e- collisions by the CLEO detector, we present the results of a study of the ψ(2S) decaying into baryon-antibaryon final states. We report the most precise measurements of the following eight modes: pp̄, ΛΛ̄, Σ+Σ+̄ (first observation), Σ0Σ0̄, Ξ-Ξ-̄, and Ξ0Ξ0̄ (first observation), and place upper limits for the modes Ξ(1530)0Ξ(1530)0̄ and Ω-Ω-̄.
