WUHAN, China - Martina Hingis has been one of the most successful tennis players in the world over the last two decades, amassing an incredible 20 Grand Slam titles across all three disciplines - five in singles, 11 in women's doubles and four in mixed doubles. She's just the third active player to have more than 20 Grand Slam titles to her name - the other two are, of course, the Williams sisters.

But this one's all about the birthday girl - we're turning back the clock and looking at her 20 majors, starting with those five singles titles. The first of those five - the Australian Open in 1997 - made Hingis, just 16 years old at the time, the youngest player to win a Grand Slam title in the Open Era.

And now, Hingis' 11 Grand Slam women's doubles titles. The first of those 11 was even more historic than her singles triumph at the 1997 Australian Open - at age 15, her doubles victory at Wimbledon in 1996 made Hingis the youngest player ever to win a Grand Slam title in any of the three disciplines.
