By Bill Cooney, PGATOUR.COM ST SIMONS ISLAND, Ga. -- Fanny Sunesson was the most successful female caddie in the history of golf. Henrik Stenson appreciated the opportunity to work with her but wished her career didn’t have to end in such a strange way. Sunesson, who recently told Swedish golf website golf.se, that she is retiring, injured her back last September while caddying for Stenson at a tournament in Switzerland. A marshal lifted a rope that accidentally tripped Sunesson, who fell and injured herself. “When I spoke to her back in 2006, she was semi-retired back then and then she came out and did five full seasons with me,” Stenson said Friday from The McGladrey Classic. “If she wasn’t ready for retirement before then, she definitely was after five years with me.” “She’s a terrific girl and a terrific caddie,” Stenson added. “It’s a shame it kind of had to end like that.” Sunesson famously caddied for Nick Faldo and won four major championships with him in the 1990s. She also caddied for Sergio Garcia and Fred Funk before taking over for Stenson. Together the two won the 2007 Accenture Match Play Championship and THE PLAYERS Championship in 2009. Stenson said Sunesson is doing well, but isn't healthy enough to continue caddying. While he didn’t completely close the door on the possibility that Sunesson would caddie one last time, he was elated to have the opportunity to work with her. “She obviously gave me a lot of comfort being as hard working and dedicated and loyal as she is,” Stenson said. “It’s a great comfort to have her on the bag. If she didn’t have the information I needed when I was out there no one else had it, either.” According to the Swedish golf website, Sunesson will focus on her role as a golf coach and advisor. She was Martin Kaymer’s mental coach when he became the world’s No. 1 player in 2011. Faldo won the 1990 British Open with Sunesson. On Friday, Faldo tweeted: "#FannySunesson--as we strode down 14th fairway Open 1990, 2 ahead to break tension Fanny asks "Are you thinking of getting a dog?"" The ability to keep her players relaxed is one of the reasons Sunesson was so successful. She was asked if she had any regrets. “Yes, to win the U.S. Open and the U.S. PGA,” Sunesson told the website. “It would have been fun to take all the majors. Since it is a bit sad that I could not finish properly with (Henrik). He deserves all the success he can get. I think he will win a major, and it would have been fun to be there when he does.” Stenson is in the top 20 at Sea Island after rounds of 67-68. “We won some nice tournaments together, obviously (THE PLAYERS),” Stenson said. “She didn’t win that with Nick so at least I contributed something nice for her CV. Kind of hard to match four majors.”
