Quantities related to B decays that are strongly suppressed in the standard model may provide early indications of non-SM physics. CDF has the world's largest heavy flavor samples and can explore rare decays with unprecedented sensitivity. We present the first observation of B0_s --> phi mu+ mu- decays (the rarest B0_s decays observed), a measurement of forward-backward asymmetry in B0 --> K* mu+ mu- competitive with world-leading results, and the first measurement of polarization amplitudes in B0_s --> phi phi decays.
