Abstract. The <phi><pi>+<pi>- production in p\=p annihilation at rest is strongly enhanced by a two step mechanism with intermediate K\=K<pi><pi> states. The relative yield of the <phi> production due to the resonant final state interaction decreases with increasing total energy of the p\=p system.
