Sara Errani and Roberta Vinci completed the career doubles Grand Slam with their victory at Wimbledon earlier this summer, having previously captured the French Open and US Open in 2012, and the Australian Open in 2013 and again in 2014.
The Italians also recently qualified for October's BNP Paribas WTA Finals Singapore presented by SC Global. Though this will be their third straight year competing at the WTA's season finale, that is one event they have yet to capture.
That is hardly something to be ashamed of, though, as only two teams in WTA history have won all four Grand Slams titles and the WTA Finals. Below is a rundown of each occurrence:
Martina Navratilova and Pam Shriver
Navratilova and Shriver won their first of their 10 WTA Finals and the first of their five Wimbledons in 1981, the first of their seven Australian Opens in 1982, the first of their four US Opens in 1983 and the first of their four French Opens in 1984. They actually ended up achieving the career Grand Slam/WTA Finals champions feat four times, as they won each major and the WTA Finals at least four times each. In fact, just in 1984 they achieved the career Grand Slam with their victories at each of the majors and the WTA Finals.
Gigi Fernández and Natasha Zvereva
Fernández and Zvereva captured the first of their five French Opens, the first of their four Wimbledons and the first of their three US Opens in 1992, and the first of their two Australian Opens and the first of their two WTA Finals in 1993. They ended up achieving the career Grand Slam/WTA Finals champions feat twice, as they won each Grand Slam and the WTA Finals at least twice each.
