We perform a Dalitz plot analysis of the decay D{sub s}{sup +}{yields}K{sup +}K{sup -}{pi}{sup +} with the CLEO-c data set of 586 pb{sup -1} of e{sup +}e{sup -} collisions accumulated at {radical}(s)=4.17 GeV. This corresponds to about 0.57x10{sup 6} D{sub s}{sup {+-}}D{sub s}*{sup {+-}} pairs from which we select 14 400 candidates with a background of roughly 15%. In contrast to previous measurements we find good agreement with our data only by including an additional f{sub 0}(1370){pi}{sup +} contribution. We measure the magnitude, phase, and fit fraction of K*(892){sup 0}K{sup +}, {phi}(1020){pi}{sup +}, K{sub 0}{sup *}(1430)K{sup +}, f{sub 0}(980){pi}{sup +}, f{sub 0}(1710){pi}{sup +}, and f{sub 0}(1370){pi}{sup +} contributions and limit the possible contributions of other KK and K{pi} resonances that could appear in this decay.
