We report the first observation of B{sub s}{sup 0}{yields}{psi}(2S){phi} decay in p{bar p} collisions at {radical}(s)=1.96 TeV using 360 pb{sup -1} of data collected by the CDF II detector at the Fermilab Tevatron. We observe 20.2{+-}5.0 and 12.3{+-}4.1 B{sub s}{sup 0}{yields}{psi}(2S){phi} candidates, in {psi}(2S){yields}{mu}{sup +}{mu}{sup -} and {psi}(2S){yields}J/{psi}{pi}{sup +}{pi}{sup -} decay modes, respectively. We present a measurement of the relative branching fraction (script B)(B{sub s}{sup 0}{yields}{psi}(2S){phi})/(script B)(B{sub s}{sup 0}{yields}J/{psi}{phi})=0.52{+-}0.13(stat){+-}0.04(syst){+-}0.06(BR) using the {psi}(2S){yields}{mu}{sup +}{mu}{sup -} decay mode.
