  The conventional use of two-body B decays to extract $\gamma$, although
theoretically clean, is currently statistics-limited. On the other hand, a bulk
of data on three-body B decays is available from $B$ factories. Applying the
flavor-SU(3)-symmetric approach proposed in Ref.\ \cite{ReyLeLorier:2011ww} to
\babar data, we find the highly promising result $\gamma = (81^{+4}_{-5} ({\rm
avg.}) \pm 5 ({\rm std.\ dev.}))^\circ$. This establishes the use of three-body
B decays as a viable alternative for the extraction of weak phases. In this
preliminary analysis we have neglected several sources of uncertainties such as
the effect of flavor-SU(3) breaking due to meson masses, and error correlations
between input experimental parameters. A better understanding of these will
improve the viability of this method.
