Tennis ace Roger Federer has become the first man to claim 20 grand slam singles titles

Today's Birthday, August 8: Swiss tennis champion Roger Federer (1981 - ).

Evergreen Swiss maestro Roger Federer's Australian Open victory earlier this year took his grand slam tally to 20, further cementing him as the most decorated men's tennis player in history.

The 37-year-old burst into tears while collecting his sixth Norman Brookes trophy after fighting off Croatian finalist Marin Cilic in a five-set thriller.

The classy veteran has maintained his world no.2 ranking despite playing less than 10 ATP events, skipping the French Open and falling in the Wimbledon quarter-finals to South African Kevin Anderson.

Born in 1981 in Basel, Switzerland, Federer grew up playing a variety of sports including soccer and tennis.

At age 13, he decided to concentrate exclusively on tennis and left home to train at the Swiss National Tennis Centre.

After winning Wimbledon boys singles and doubles titles, Federer joined the professional circuit in 1998.

The 19-year-old prodigy announced his arrival on the big stage in 2001 after defeating 14-time major champion Pete Sampras in the fourth round of Wimbledon.

But Federer, known for his majestic one-hand backhand, also developed a reputation as a temperamental youngster.

The shock death of his childhood coach Peter Carter a year later proved a crucial turning point.

His breakthrough grand slam win over Australian Mark Philippoussis at Wimbledon in 2003 kickstarted a period of unparalleled dominance.

Federer, who spent a record 310 weeks at world No.1, made a staggering 18 of 19 grand slam finals between 2005 to 2010.

The bandana-wearing ace has notched a record 20 grand slams, three ahead of career rival and "King of Clay" Rafael Nadal.

A knee injury in 2016 resulted in a six-month layoff and threatened to curtail the twilight of his career, but he recovered to claim back-to-back Australian Opens and an eighth Wimbledon crown in 2017.

Since meeting wife Mirka Vavrinec at the Sydney Olympics in 2000, the pair has welcomed two sets of twins, Myla and Charlene in 2009, and Leo and Lenny in 2014.

Federer effectively ended his 24-year association with Nike in July to sign a reported $US300 million ($AU408 million), 10-year deal with lesser-known Japanese clothing brand Uniqlo.
