A comparative study of amplitude zeros in Wγ and WZ production in hadronic collisions is presented. The Standard Model amplitude for q1 q2 → W^± Z at the Born-level is shown to exhibit an approximate zero located at cosθ= (gq1- + gq2-) / (gq1- - gq2-) at high energies, where the gqi- (i=1,2) are the left-handed couplings of the Z-boson to quarks and θ is the center of mass scattering angle of the W-boson. This approximate zero is similar to the well-known radiation zero in Wγ production. Prospects to observe the amplitude zeros using rapidity correlations between the final state particles are explored.
