Sharapova won the U.S. Open in 2006 and the AustralianOpen in 2008, and she reached No. 1 in the world four different times, but only stayed there for a total of 17 weeks.
The world No. 2 had to work hard for victory against Errani, who she defeated in last year's French Open to achieve her career grand slam, having previously won Wimbledon (2004), the U.S. Open (2006) and the AustralianOpen(2008).
