PORTLAND, Ore. - Sweden's Sophie Gustafson retired from the LPGA Tour on Friday after missing the cut in the Safeway Classic. "It's with mixed emotions that I'm now choosing to step away from the LPGA," tweeted Gustafson, who has battled a severe stuttering problem. Thanks for all your kindness over the years. The 39-year-old Gustafson won the last of her five LPGA Tour titles in 2009. She also won 13 times on the Ladies European Tour and topped that circuit's money list three times. The long-hitter played in eight Solheim Cups, going 13-12-6. She was 4-0 in Europe's 2011 victory in Ireland and made an inspirational statement at the event by doing a lengthy television interview. Last week at the CN Canadian Women's Open, she finished tied for 45th. In her final tournament in Portland, Gustafson had rounds of 73 and 76 at Columbia Edgewater. "@SophieGustafson my partner;)) you've been the best!!" tweeted Norway's Suzann Pettersen, a teammate of Gustafson's on the Solheim Cup team. "ill miss you, thanks for all the great memories." "Sorry to hear you are leaving us," tweeted fellow Swede Maria Hjorth. But I'm sure you have thought hard about it and and are making what is the right decision for yourself! "Always enjoyed playing with you and watching your game!" tweeted Beth Daniel. Hope the next chapter is as good as the last! wow! What a hard decision I'm sure," tweeted PGA Tour player Arron Oberholser. I'm happy and sad for you at the same time, Sophie. Best of luck going forward.,
