We present measurements of the branching fraction and fraction of longitudinal polarization for the decay B{sup +}{yields}K*{sup 0}K*{sup +} with a sample of (467{+-}5)x10{sup 6} BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at the SLAC National Accelerator Laboratory. We obtain the branching fraction B(B{sup +}{yields}K*{sup 0}K*{sup +})=(1.2{+-}0.5{+-}0.1)x10{sup -6} with a significance of 3.7 standard deviations including systematic uncertainties. We measure the fraction of longitudinal polarization f{sub L}=0.75{sub -0.26}{sup +0.16}{+-}0.03. The first error quoted is statistical and the second is systematic.
