MELBOURNE, Australia — Andre Agassi held up his end of the bargain in the Australian Open. Now wife Steffi Graf and the rest of Agassi's entourage has to step up.
Graf, who won 22 Grand Slam singles titles before retiring three years ago, promised to join her husband in mixed doubles at the French Open if he won his fourth Australian Open title.
"She won't like it, but it's my responsibility to make it happen," Agassi said Sunday after winning at Melbourne Park.
Coach Darren Cahill has to shave his head "in my bathroom, with my clippers and at my doing," and fitness trainer Gil Reyes, a non-drinker, has to down one of Andre's "special" margaritas.
The 32-year-old Agassi overwhelmed Rainer Schuettler on Sunday in a 76-minute, 6-2, 6-2, 6-1 demolition.
It was his eighth Grand Slam title and his fifth in the last three years, making him the most dominant player of the last three years. He also became the oldest man to win a Grand Slam singles title since Ken Rosewall won the 1972 Australian Open at 37.
"You never know when it's your last, but I'll never forget being here," Agassi said. "I'll never forget the love and support here. I feel like I'm half Australian."
On Saturday, Serena Williams completed her "Serena Slam" by winning a fourth consecutive major.
And, for the fourth time in as many Grand Slam finals, she beat older sister Venus. Only this time, it went to three sets and it gave Serena "a new perspective on things."
The latest of the Sister Slam matches went 7-6 (4), 3-6, 6-4 and lasted 2 hours, 22 minutes, almost double the time it took Agassi to dispatch Schuettler.
Serena won the French Open, Wimbledon and U.S. Open in 2002 and, with the Australian title, it marked only the sixth time a woman has held all four major championships at once and the first since Graf in 1994.
It might not be a true Grand Slam — all four major titles in a calendar year — but the accomplishment is special.
"I never get choked up, but I'm really emotional right now," Serena said. "I'm really, really, really happy."
Venus, who at 22 is 15 months older than Serena, wished "I could have been the winner."
"Of course, you have a great champion in Serena and she has won all four Grand Slams, which is something I'd love to do," she said. "So, yeah, I'd kind of be just like her."
Serena holds a 5-4 career edge over Venus in major titles and has a 6-5 lead in head-to-head matches. Serena collected $654,000 for this victory and Venus won $327,000.
Team Williams also won the women's doubles, on the eve of the singles final, beating Paola Suarez and Virginia Ruano Pascual 4-6, 6-4, 6-3.
If Graf needed any encouragement to return, it was a challenge from former No. 1 Martina Navratilova for a mixed doubles match at Roland Garros.
At age 46, Navratilova won her 57th Grand Slam title, serving out the match as she and India's Leander Paes beat Todd Woodbridge and Eleni Daniilidou 6-4, 7-5 for the mixed doubles championship.
It was her first mixed title in the Australian and completed a "Grand" Grand Slam — at least one title each in singles, doubles and mixed doubles in all four major tournaments.
"This goes beyond any wildest dream," said Navratilova, who was playing in her first Grand Slam final in almost eight years.
Navratilova won 18 singles and 31 doubles Grand Slam titles.
At 46 years and 3 months, she was a month older than the previous oldest winner in a Grand Slam event, Australian Norman Brookes in the 1924 Australian men's doubles.
