The Collider Detector at Fermilab (CDF) experiment performed the first measurement of the time-evolution of flavor-tagged B{sub s}{sup 0} {yields} J/{psi}{phi} decays, which probes mixing-induced CP-violation in the B{sub s}{sup 0} sector. Any sizable deviation from zero of the phase {beta}{sub s}J/{psi}{phi}, accessible through interference of the {bar b} {yields} {bar c}c{bar s} quark-level process accompanied or not by B{sub s}{sup 0}-{bar B}{sub s}{sup 0} mixing, would be unambiguous indication of physics beyond the Standard Model. I report CDF results obtained in 1.35 fb{sup -1}, a recent extension to a larger dataset corresponding to 2.8 fb{sup -1}, and future projections.
