A combined fit is performed to the BaBar and Belle measurements of the e{sup +}e{sup -} {yields} {phi}{pi}{sup +}{pi}{sup -} and {phi}f{sub 0}(980) cross sections for center-of-mass energy between threshold and 3.0 GeV. The resonance parameters of the {phi}(1680) and Y(2175) are determined. The mass is (1681{sub -12}{sup +10}) MeV/c{sup 2} and the width is (221{sub -24}{sup +34}) MeV/c{sup 2} for the {phi}(1680), and the mass is (2117{sub -49}{sup +59}) MeV/c{sup 2} and the width is (164{sub -80}{sup +69}) MeV/c{sup 2} for the Y(2175). These information will shed light on the understanding of the nature of the excited {phi} and Y states observed in e{sup +}e{sup -} annihilation.
