user: Background: Stefanie Graf was born on 14 June 1969, in Mannheim, Baden-Wurttemberg, West Germany, to Heidi Schalk and Peter Graf (18 June 1938 - 30 November 2013), a car and insurance salesman. When she was nine years old her family moved to the neighbouring town of Bruhl. She has a younger brother Michael. Graf was introduced to tennis by her father, an aspiring tennis coach, who taught his three-year-old daughter how to swing a wooden racket in the family's living room.
Context: In late 1999 and early 2000, as part of her Farewell Tour, Graf played a series of exhibition matches against former rivals in New Zealand, Japan, Spain, Germany and South Africa. She played Jelena Dokic in Christchurch, New Zealand, Amanda Coetzer in Durban, South Africa, and her former rival Arantxa Sanchez Vicario in Zaragoza, Spain. It was Graf and Sanchez Vicario's first head-to-head meeting since 1996. In February 2000, Graf played against Kimiko Date at Nagoya Rainbow Hall in Tokyo, winning in three sets. In September 2004, Graf dispatched her former doubles partner Gabriela Sabatini in straight sets, in an exhibition match played in Berlin, Germany. She was also in Berlin to host a charity gala, as well as inaugurating a tennis stadium renamed the "Steffi Graf Stadion". Proceeds from her match against Sabatini went to Graf's foundation, "Children for Tomorrow".  In July 2005, Graf competed in one tie of World Team Tennis (WTT) on the Houston Wranglers team. She was beaten in two out of three matches, with each match being one set. Graf lost her singles match to Elena Likhovtseva 5-4. She teamed with Ansley Cargill in women's doubles against Anna Kournikova and Likhovtseva but lost 5-2. She was successful, however, in the mixed doubles match. Graf completely ruled out a return to professional tennis. In October, Graf defeated Sabatini in an exhibition match in Mannheim, Germany, winning both of their sets. Like the exhibition match the previous year against Sabatini, proceeds went to "Children for Tomorrow".  In 2008 Graf lost an exhibition match against Kimiko Date at Ariake Colosseum in Tokyo. As part of the event, billed as "Dream Match 2008", she defeated Martina Navratilova in a one-set affair 8-7, with Graf winning a tiebreaker 10-5. It was the first time in 14 years Graf had played Navratilova. Graf played a singles exhibition match against Kim Clijsters and a mixed doubles exhibition alongside husband Andre Agassi against Tim Henman and Clijsters as part of a test event and celebration for the newly installed roof over Wimbledon's Centre Court in 2009. She lost a lengthy one-set singles match to Clijsters and also the mixed doubles.  In 2010, Graf participated in the WTT Smash Hits exhibition in Washington, D.C. to support the Elton John AIDS Foundation. She and Agassi, her husband, were on Team Elton John, which competed against Team Billie Jean King. Graf played in the celebrity doubles, women's doubles, and mixed doubles before straining her left calf muscle and being replaced by Anna Kournikova.

Background: Tara Ann VanDerveer (born June 26, 1953) is an American basketball coach who has been the head women's basketball coach at Stanford University since 1985. Designated the Setsuko Ishiyama Director of Women's Basketball, VanDerveer led the Stanford Cardinal to two NCAA Women's Division I Basketball Championships: in 1990 and 1992. She stepped away from the Stanford program for a year to serve as the U.S. national team head coach at the 1996 Olympic Games. VanDerveer is the 1990 Naismith National Coach of the Year and a ten-time Pac-12 Coach of the Year.
Context: VanDerveer was born on June 26, 1953, to Dunbar and Rita VanDerveer, who named their first child "Tara" after the plantation in Gone with the Wind. She was born in Melrose, Massachusetts, a part of Greater Boston, but grew up in a small town in West Hill, near Schenectady, New York. Her parents were interested in a well-rounded education. Her father was studying for a doctorate at the school now known as the University at Albany. He took the family to Chautauqua in the summer, where she immersed in arts as well as sports. At the age of ten, her parents bought her a flute, and arranged for lessons. Two years later, one of the premier flutists in the world was staying in Chautauqua, and her father arranged for lessons with this distinguished teacher. Although she learned to play, she did not enjoy the experience, and gave up the flute in ninth grade. The love of music stayed with her though, and in later years she would take up the piano.  There were no sports teams for girls when she was in high school, but she played a number of sports including basketball, in rec leagues and pickup. When she was younger, she played with both boys and girls. As she entered her high school years, the girls dropped out for other interests, so she was more apt to play with boys. To help make sure she would be chosen, she bought the best basketball she could afford, so if the boys wanted to play with her basketball, they would have to pick her.  Her father wasn't completely supportive of her basketball interest, calling her in from the neighbor's basketball hoop, telling her, "Basketball won't take you anywhere. Come in and do your algebra." Tara was equally certain that algebra wasn't going to take her anywhere. Her family moved to Niagara Falls in her sophomore year in high school. The house in West Hill had a gravel driveway, making a basketball hoop impractical, but when her parents got her a hoop for Christmas when they were in Niagara Falls. By then, she thought she was too old for basketball, although she would take it up again after she transferred to Buffalo Seminary, an all-girls college preparatory school, in her junior year. She ended up earning a place in the Buffalo Seminary's Athletic Hall of Fame.
