Steffi was introduced to tennis by her father
Peter Graf, a car and insurance salesman and aspiring tennis coach, who taught his three-year-old daughter how to swing a wooden racket in the family's living room. She began practicing on a court at the age of four and played in her first tournament at five. She soon began winning junior tournaments with regularity, and in
1982 she won the European Championships 12s and 18s.
Graf played in her first professional tournament in October
1982 at Stuttgart, Germany. She lost her first round match 6-4, 6-0 to
Tracy Austin, a two-time
U.S. Open champion and former World No. 1 player. Austin remarked of the then-thirteen year old Graf that "there are hundreds of girls like her in America." Twelve years later, Graf defeated Austin 6-0, 6-0 during a second round match in
Indian Wells, California, which was their second and last match against each other.
At the start of her first full professional season in 1983, the 13-year-old Graf was ranked No. 124. She won no titles in the next three years, but her game improved consistently and her ranking climbed steadily to No. 98 in 1983, No. 22 in
1984, and No. 6 in
1985. In 1984, she first gained international attention when she almost upset the #10 seed,
Jo Durie of the
United Kingdom, in a fourth round
Centre Court match at
Wimbledon. In August, she represented
West Germany in the tennis demonstration event at the
Olympic Games in
Los Angeles and won the event.
Graf's schedule was closely controlled by her father, Peter Graf, who limited her play so that she would not burn out. In 1985, for instance, she played only 10 events leading up to the
U.S. Open, whereas another up-and-coming star,
Gabriela Sabatini of
Argentina, who was a year younger than Graf, played 21. Peter also kept a tight rein on Graf's personal life. Social invitations on the tour were often declined as Graf's focus was kept on practising and match play. Working with her father and then-coach
Pavel Slozil, Graf typically practiced for up to four hours a day, often heading straight from airports to practice courts. This narrow focus meant that Graf, already shy and retiring by nature, made few friends on the tour in her early years, but it led to a steady improvement in her play.
1985 and early 1986 saw her emerge as the top challenger to the dominance of
Martina Navratilova and
Chris Evert. During that period, she lost six times to Evert and three times to Navratilova, all in straight sets. She did not win a tournament but consistently reached tournament finals and semifinals, with the highlight being her semifinal loss to Navratilova at the U.S Open.
On
April 13, 1986, Graf won her first WTA tournament and beat Evert for the first time in the final of the
Family Circle Cup in
Hilton Head, South Carolina. She never lost to Evert again, beating her a further seven times over the next three and a half years. She then won her next three tournaments at
Amelia Island, Charleston, and
Berlin, culminating in a 6-2, 6-3 defeat of Navratilova in the final of the latter. At the
French Open, Graf was the third seed but was seen by many as the tournament favorite. However, she caught a virus and lost to
Hana Mandlikova in the quarterfinals 2-6, 7-6, 6-1. The illness caused her to miss Wimbledon, and an accident where she broke a toe several weeks later also curtailed her momentum. She returned to win a small tournament at Mahwah just before the U.S Open where, in one of the most anticipated matches of the year, she encountered Navratilova in a semifinal. The match was played over two days with Navratilova finally winning after saving three match points 6-1, 6-7, 7-6. Graf then won three consecutive indoor titles at
Tokyo, Zurich, and
Brighton, before once again contending with Navratilova at the season-ending Virginia Slims Championships in
New York City. This time, Navratilova beat Graf easily 7-6, 6-3, 6-2.
