Using the soft-collinear effective theory we derive the factorization theorem for the decays B{yields}M{sub 1}M{sub 2} with M{sub 1,2}={pi},K,{rho},K*, at leading order in {lambda}/E{sub M} and {lambda}/m{sub b}. The results derived here apply even if {alpha}{sub s}(E{sub M}{lambda}) is not perturbative, and we prove that the physics sensitive to the E{lambda} scale is the same in B{yields}M{sub 1}M{sub 2} and B{yields}M form factors. We argue that cc penguins could give long-distance effects at leading order. Decays to two transversely polarized vector mesons are discussed. Analyzing B{yields}{pi}{pi} we find predictions for B{sup 0}{yields}{pi}{sup 0}{pi}{sup 0} and vertical bar V{sub ub} vertical bar f{sub +}{sup B0}{yields}{pi}(0) as a function of {gamma}.
