%X We analyze the f(0)(1810) state recently observed by the BES collaboration via radiative J/psi decay to a resonant phi omega spectrum and confront it with DM2 data and glueball theory. The DM2 group only measured omega omega decays and reported a pseudoscalar but no scalar resonance in this mass region. A rescattering mechanism from the open flavored K (K) over bar decay channel is considered to explain why the resonance is only seen in the flavor asymmetric omega phi branch along with a discussion of positive C-parity charmonia decays to strengthen the case for preferred open flavor glueball decays. We also calculate the total decay width of a glueball with this mass to be roughly 100 M (K) over bar eV, in agreement with the narrow, newly found f(0), and smaller than the expected estimate of 200-400 MeV. We conclude that this discovered scalar hadron deserves further experimental investigation, especially in the K channel, and if shown to be different from the f(0)(1710), will become a solid glueball candidate. Finally we comment on other, but less likely, possible assignments for this state.
