The three-time U.S. Women's Open champion will become a USGA ambassador, involved in the Rules of Golf and with programs to grow the game.
"Annika has earned a rare place in golf's history, and we are very privileged to bring her aboard the USGA," president Jim Vernon said.
Sorenstam made a brief appearance at Torrey Pines, coming to the U.S. Open for corporate work with Lexus. The 37-year-old Swede is retiring after this year.
SHARP EYE: Yani Tseng earned $300,000 for her victory two weeks ago in the McDonald's LPGA Championship, making her the first rookie in 10 years to win an LPGA major. She is fourth on the money list with $835,241.
What to do with her earnings? For starters, she wants to buy a billiards table.
Tseng is quite accomplished with the cue stick, and some say she can run the table on just about anyone.
"I'm pretty good," she said during the first round of the U.S. Open, when she followed the Tiger Woods -Phil Mickelson -Adam Scott group. "Helps me with my putting."
BACK IN THE BOOTH: Curtis Strange looked as comfortable as ever in the broadcast booth at the U.S. Open, where he spent 21/2 hours each of the first two rounds on ESPN with Mike Tirico . They were the ABC tandem for eight years through 2004.
He also joined Peter Jacobsen with NBC Sports' Bob Costas for brief observations on the weekend.
"It was a lot of fun," Strange said. "I'd love for it to work into a couple more events."
