We analyze the f_0(1810) state recently observed by the BES collaboration viaradiative J/\psi decay to a resonant \phi\omega spectrum and confront it withDM2 data and glueball theory. The DM2 group only measured \omega\omega decaysand reported a pseudoscalar but no scalar resonance in this mass region. Arescattering mechanism from the open flavored KKbar decay channel is consideredto explain why the resonance is only seen in the flavor asymmetric \omega\phibranch along with a discussion of positive C parity charmonia decays tostrengthen the case for preferred open flavor glueball decays. We alsocalculate the total glueball decay width to be roughly 100 MeV, in agreementwith the narrow, newly found f_0, and smaller than the expected estimate of200-400 MeV. We conclude that this discovered scalar hadron is a solid glueballcandidate and deserves further experimental investigation, especially in theK-Kbar channel. Finally we comment on other, but less likely, possibleassignments for this state.Comment: 11 pages, 4 figures. Major substantive additions, including an  ab-initio, QCD-based computation of the glueball inclusive decay width,  evaluation of final state effects, and enhanced discussion of several  alternative possibilities. Our conclusions are unchanged: the BES f_0(1810)  is a promising glueball candidat
