Analyzing power measurements from the ($\overrightarrow{p},d$) reaction on ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$ and ${}_{}{}^{120}{}_{}{}^{}\mathrm{Sn}$ have been made using a 90 MeV polarized proton beam. The spin of the broad structure near 5 MeV excitation energy in ${}_{}{}^{119}{}_{}{}^{}\mathrm{Sn}$ has been unambiguously determined to be 9/2 from comparison with the empirical analyzing power for the ground state of ${}_{}{}^{89}{}_{}{}^{}\mathrm{Zr}$ and from distorted wave Born approximation calculations.
