Four separate experiments [A. Etkin et al., Phys. Rev. Lett. 41, 784 (1978).][A. Etkin et al., Phys. Rev. Lett. 49, 1620 (1982).][A. Etkin et al., Phys. Lett. B 165, 217 (1985).][A. Etkin et al., Phys. Lett. B 201, 568 (1988).] observing the OZI forbidden disconnected reaction {pi}{sup -}p{yields}{phi}{phi}n with increasing statistics were consistent. These experiments, very selectively, completely broke down the OZI suppression by three {phi}{phi} resonances with I{sup G}J{sup PC}=0{sup +}2{sup ++} in the observed mass region 2.038 GeV to 2.600 GeV. The only viable proposed explanation has been that the I{sup G}J{sup PC}=0{sup +}2{sup ++} glueball expected in this mass region caused the hard glue in the disconnection to resonate and very selectively break down the OZI suppression for its quantum numbers only. Recently a pp central production spin analysis found that the f{sub 2}(1950) had a dominant decay mode f{sub 2}(1270){pi}{pi} [D. Barberis et al., Phys. Lett. B 471, 440 (2000).]). We consider if it is related to the {phi}{phi} resonances, and find that it likely is.
