She Has Won 14 Grand Slam Women's Doubles Together With Venus

Winning 14 Grand Slam women's doubles matches with Venus Williams is Serena Williams' sixth significant accomplishment. Along with her sister Venus, Serena owns several doubles records in addition to being a dominant singles winner. Since 1997, Venus and Serena have occasionally played doubles together. At the 1999 French Open, they won a Grand Slam title for the first time, marking their first significant achievement. Serena was 17 at the time, and Venus was 18 at the time. The team achieved the Career Doubles Grand Slam by winning the 2001 Australian Open. They also achieved a career doubles grand slam because they had already won the gold medal at the 2000 Olympics. Venus and Serena have won 14 Grand Slam doubles championships overall.

This is the third-most titles in women's doubles, after Navratilova and Pam Shriver's record-breaking 20 titles and Natasha Zvereva's 18 titles (14 with Gigi Fernández). At major slams, Venus and Serena have a 125-14 win-loss record. They have also never lost a Grand Slam championship.
