We calculate the Drell-Yan production cross sections and differential distributions in the transverse momentum and rapidity of the J{sup PC}=1{sup --} exotic hadrons {phi}(2170), X(4260), and Y{sub b}(10890) at the LHC and the Tevatron. These hadrons are tetraquark (four-quark) candidates, with a hidden ss, cc, and bb quark pair, respectively. In deriving the distributions, we include the order {alpha}{sub s} QCD corrections, resum the large logarithms in the small transverse momentum region in the impact-parameter formalism, and use the state of the art parton distribution functions. Production rates for the processes pp(p){yields}{phi}(2170) ({yields}{phi}(1020){pi}{sup +}{pi}{sup -}{yields}K{sup +}K{sup -}{pi}{sup +}{pi}{sup -})+..., pp(p){yields}X(4260)({yields}J/{psi}{pi}{sup +}{pi}{sup -}{yields}{mu}{sup +}{mu}{sup -}{pi}{sup +}{pi}{sup -})+..., and pp(p){yields}Y{sub b}(10890)({yields}{Upsilon}(1S,2S,3S){pi}{sup +}{pi}{sup -}{yields}{mu}{sup +}{mu}{sup -}{pi}{sup +}{pi}{sup -})+... are presented. Their measurements will help in understanding the dynamics of these exotic hadrons.
