Editing Steffi Graf (section)

====1991====
A mixture of injury problems, personal difficulties, and loss of form made 1991 a tough year for Graf. Seles established herself as the new dominant player on the women's tour, winning the Australian Open, French Open, and US Open and, in March, ending Graf's record 186 consecutive-weeks hold on the World No. 1 ranking.<ref name="wta_spotlight"/> Graf briefly regained the top ranking after winning at Wimbledon but lost it again after her loss to Navratilova at the US Open.

Graf lost an [[1991 Australian Open|Australian Open]] quarterfinal to [[Jana Novotná]], the first time she did not reach the semifinals of a Grand Slam singles tournament since the 1986 French Open. She then lost to Sabatini in her next three tournaments before winning the U.S. Hardcourt Championships in [[San Antonio]], beating Monica Seles in the final. After losing a fifth straight time to Sabatini in [[Bausch & Lomb Championships|Amelia Island, Florida]], Graf again defeated Seles in the [[Hamburg Masters|Hamburg]] final. Following her tournament victory in [[WTA German Open|German Open]] in Berlin, Graf suffered one of the worst defeats of her career in a [[1991 French Open|French Open]] semifinal where she won only two games against Sánchez Vicario and lost her first 6–0 set since 1984. At [[1991 Wimbledon Championships|Wimbledon]], however, Graf captured her third women's crown, this time at Sabatini's expense. Sabatini served for the match twice, and was two points away from her first Wimbledon title. After breaking Sabatini's serve to even the third set at 6–6, Graf defeated Sabatini by winning the next two games to take the match 6–4, 3–6, 8–6. Martina Navratilova then defeated Graf 7–6, 6–7, 6–4 in a [[1991 US Open (tennis)|US Open]] semifinal, the first time she had beaten Graf in four years. Graf then won in Leipzig, with her 500th career victory coming in a quarterfinal against [[Judith Wiesner]]. After winning two more indoor tournaments at Zurich and [[Brighton International|Brighton]], she failed once again in the Virginia Slims Championships, losing her quarterfinal to Novotná. Soon after, she split with her long-time coach, Pavel Složil.
