Jan Stephenson fired a 4-under-par 68 Sunday to edge Nancy Lopez by a stroke and win the $225,000 Safeco tournament at Kent, Wash.
Last weekend, Lopez beat Stephenson by a stroke to win the Cellular One-Ping Championship in Portland, Ore.
Stephenson shot a 72-hole total of 277 and won $33,750.
Lopez started the day three shots behind the leaders and closed with a 67 to finish with 278.
Missie Berteotti, who shared the lead after the second and third rounds, shot a par 72 for 280 to finish third, the best she has done in her two years on the LPGA tour.
Heavy rain forced postponement of the final round of the $600,000 Greater Milwaukee Open, with Gary Hallberg, Dan Pohl, Wayne Levi and Bill Kratzert tied for the lead.
