  In February 1999, Williams won her first professional singles title when she defeated Amélie Mauresmo in the final of the Open Gaz de France in Paris. In March, Williams won her first WTA 1000 event at the Evert Cup in California, defeating Steffi Graf in the final. At the Miami Masters, Williams had her 16-match winning streak ended by her sister in the first all-sister singles final in WTA history. In the doubles event at the French Open, she and Venus won the title after defeating Hingis and Anna Kournikova in the final.
  
  Williams missed Wimbledon in 1999 due to injury. When she returned to the tour two months later, she made her Fed Cup debut, defeating Rita Grande to send the United States to the final. She then won her third title at the JPMorgan Chase Open, beating Julie Halard-Decugis in the final. At the US Open, Williams defeated Grand Slam champions Kim Clijsters, Conchita Martínez, Monica Seles, and Lindsay Davenport (the defending champion) in consecutive matches to reach the final, where she defeated No.1-ranked Hingis. Williams became the second African-American woman to win a Grand Slam singles tournament, after Althea Gibson. The Williams sisters also won the doubles event at this tournament, making Serena the fifth woman in the Open Era to win both singles and doubles at the same major event. To complete her 1999 season, Williams won a doubles match against Russia in the Fed Cup final to help the US win the title. Williams ended the year ranked in a career-high world No.4 in just her second full year on the main tour.
