Sophie Gustafson of Sweden 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."
She gave no indication of how long she'd been considering retirement, or what her future plans might include.
Gustafson, 39, 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. She entered the week ranked No. 131 on the LPGA Tour money list.
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.
Ron Sirak of Golf World wrote an excellent profile on Gustafson, detailing her lifelong battle with stuttering, back in early in 2012. If you're not familiar with her story, I encourage you to check it out.
UPDATE: Beth Ann Baldry over at Golfweek reported Saturday that Gustafson plans to return to the Ladies European Tour, where she dominated early in her career. You can read her story here.
