  We report on the discovery of eleven multimode SX Phoenicis--type blue
stragglers in the field of the southern globular cluster NGC 3201. In these
variables both radial and non-radial modes are excited. For three variables the
derived period ratio is close to that observed in SX Phoenicis itself,
suggesting that these stars are pulsating in the fundamental and the
first-overtone radial modes. Using the McNamara (1997) period-luminosity
relation we have estimated the apparent distance modulus to NGC 3201 to be
14.08$\pm0.06\pm0.1$mag.
