Roger Federer and the Top 7 Swiss Players in Tennis History | News, Scores, Highlights, Stats, and Rumors

Martina Hingis, known as the Swiss Miss, was one of the most successful women's tennis players and was world No. 1 for 209 weeks.

She won five Grand Slam singles titles, nine Grand Slam doubles titles and one Grand Slam mixed doubles title in her career. 

Hingis, who started playing tennis when she was two and entered her first tournament when she was four, was the "youngest ever" at most of her accomplishments.

She was 12 when she became the youngest ever Grand Slam juniors title winner at the French Open.

She was 15 when she became the youngest Grand Slam champion, winning the women's doubles title at Wimbledon 1996.

She was 16 when she became the youngest person ever to win a Grand Slam singles title at the 1997 Australian Open.

Later that year, she became the youngest player ever to be world No. 1.

Hingis, age 22, had a premature retirement in 2003 citing injuries. She was, however, to make a comeback in the 2006 season.

The Swiss Miss celebrated her comeback by winning her first-ever Grand Slam mixed doubles title with Mahesh Bhupathi at the 2006 Australian Open.

After clawing her way back up to No. 7 in the rankings by the end of the year, Hingis had her comeback stint cut short the following year after testing positive for cocaine and was banned for two years.

An emotional Hingis denied the charges and cut off all contacts with the sport again.

However, she is currently contemplating yet another return to the sport for the 2012 London Olympics.
