Phil and Amy Mickelson
Someday Phil Mickelson will be the captain of the U.S. Ryder Cup team, and it's fun to speculate about what kind of captain he will be. Friendly? Aloof? Overanalytical? Reckless? Who knows? Phil is large, he contains multitudes. However, there is no question what kind of captain's wife Amy will be. She'll be warm, charming, full of energy and popular with the players on both teams, their wives, and the fans.

Nancy Lopez and Ray Knight
Talk about a power-hitting power couple. Nancy Lopez, a three-time major winner and one of the most popular LPGA players ever, and all-star third baseman Ray Knight, one of the heroes of the New York Mets' 1986 World Series team, have been married since 1982.
"I just felt like we were going to be pretty ordinary," Lopez told SI in 1986. "I loved baseball and Ray loved golf, and we were in our own little world. We never thought about everything that would come later."

Nick Faldo and Fanny Sunessen
When Nick Faldo showed up with new Swedish caddie Fanny Sunesson at the Skins Game in Australia in early 1990, one British tabloid tried to stir up a scandal with the headline "Nick's Chick." However, Faldo and Sunesson's relationship was all business, and Sunesson proved herself to be one of the Tour's top caddies as Faldo won both the Masters and the British Open that year.
Sunesson is now Henrik Stenson's caddie. And no, she doesn't have trouble carrying that 40-pound bag. "It's no big deal," Sunesson says. "I'm used to it. I carry on both shoulders, and I'm strong."

Greg Norman and Chris Evert
This totally blond couple burned brightly from their marriage in June 2008 to their separation in October 2009. For their honeymoon, Norman decided to play the British Open at Birkdale and nearly won while Evert watched every shot. The Hall of Fame golfer and the Hall of Fame tennis player were known for being overly affectionate in public kind of like the 'schmoopie'" episode of Seinfeld. Evert's brother John told SI in 2009: "They hold hands and kiss in public, and you don't want to be around them in a private setting." He laughs. "I'm like, 'Guys, could you take it somewhere else?'"

Adam Scott and Ana Ivanovic
There must something with golfers and tennis players. Australian Adam Scott and Serbian tennis player Ana Ivanovic began dating in 2009, and soon afterward Scott was seen at Wimbledon and Ivanovic was turning heads on golf courses. The relationship coincided with Scott's worst slump as a pro. In September 2010, The Sydney Morning Herald reported the couple had called it splits.

Sergio Garcia and Martina Hingis

Babe Didrikson and George Zaharias
When they open the Sports Power Couple Hall of Fame, Babe and George will get their own wing. After winning two gold medals and one silver medal in track and field at the 1932 Olympics, Babe took up golf in 1935 and just three years later she played in the Los Angeles Open, a men's event. She shot 81 and 84 to miss the cut, but no one gave her any grief: her playing partner was her husband, 300-pound pro wrestler George Zaharias. Babe made the two-day cut at the 1945 Los Angeles Open (she's still the only woman to make the cut at a regular PGA Tour event), and she became America's first female golf celebrity, winning 41 times on the LPGA Tour.

Natalie Gulbis and Ben Roethlisburger
The Anna Kournikova of golf and the, uh, Charlie Sheen of football (wait, that's not fair to Charlie) dated in 2005, and they're still friends. When Gulbis played a round with Roethlisberger in May 2010, after his off-field troubles, she called him "a great guy."

Jyoti Randhawa and Chitrangada Singh
Adam Scott has nothing on Jyoti Randhawa. The Indian golfer, ranked 344th in the world, is married to Indian movie actress Chitrangada Singh. Jyoti has won eight times on the Asian Tour and has finished second at the 2004 Johnnie Walker Classic on the European Tour. Chirangada, who won the Bollywood Movie Award for Best Debut in 2005, told The Times of India that the media doesn't much bother her at her husband's golf events. "The golfing media is too involved about the golfers and their game," Chirangada said.

Corey and Lisa Pavin
The Captain and Captainness of the 2010 U.S. Ryder Cup team, Corey was famously nicknamed "Bulldog" for his toughness on the course, and his wife, Lisa, brought that same attitude to her Ryder Cup role. She did everything from helping pick the team uniforms to posing for sexy photos wrapped only in an American flag to choosing menus and team gifts. She even feuded with reporters. "My role is only to help Corey, to step in wherever he needs me to step in," Lisa told Robert Lusitech of FOX Sports.
Lisa added that the players' wives have a crucial role at the Ryder Cup. "Golf is a very individual sport, so at the end of the day when you come home, your wife is your best friend, your confidante, your lover, your sports psychologist," she told FOX Sports. "A wife plays a very big role in a golfer's life. I think a wife's as big a part of your team as your caddie."

Michelle Wie and Robin Lopez
Another Power Couple that couldn't stand the test of time, Michelle and the 7-foot-1 Phoenix Suns center dated while they were both at Stanford in 2008, according to SI. Michelle denied the two were an item in an April 2009 Korean Vogue magazine article, but she did confirm that she likes tall guys:
"My height is 183 centimeters [6 feet], so he must be taller than that. A guy that is self-confident, self-aware, and fun... the basketball player that I was [linked to] at Stanford, Robin Lopez, is just a friend."

Jack and Barbara Nicklaus
Jack and Barbara Nicklaus celebrated their 50th wedding anniversary in the summer of 2010, so Barbara has been with Jack for all 18 majors, all 73 PGA Tour wins and all six Ryder Cups as a player. Jack always says that marrying Barbara, whom he met when they were both freshmen at Ohio State, was his greatest achievement. How important was Barbara to Jack's career? Lee Trevino called Barbara "the Rock of Gibraltar," while Deane Beman called her "the 15th club."
"If your partner in life is also your best friend, it's truly invaluable," Jack wrote in his autobiography. "I shudder to think about where I would be today, what I might have missed, how less fulfilling my life would have been were Barbara not with me every step of the way."
