One of the most dominant forces in tennis and possibly all of sports is Roger Federer. Federer has won 16 Grand Slam singles titles, which is more than any other male player, and is also the only male player besides Andre Agassi to win a Grand Slam on three different surfaces.

Federer was born in Basel, Switzerland. At the age of 4, he became infatuated with tennis after watching his idol, Boris Becker, win his first Wimbledon title. He began playing tennis at age 6 and started training three times a week. At the age of 10, Federer started training with tennis coach Adolf Kacovsky at the Old Boys Tennis Club.

In 1998, Federer competed in his first professional tournament, only to lose to Lucas Arnold Ker. He earned his first win at the Milan Indoor tournament, defeating Julien Boutter.

In 2003, Federer won his first Slam at the Wimbledon championships and has been doing well ever since. He won three Slams in 2004, three in 2006 and reached four Slam finals the same year.

2004 was also the beginning of what would become one of the best rivalries in sports today, when the 17-year-old Rafael Nadal nearly upset number one ranked Roger Federer in the Miami Masters. Later that same year, Nadal defeated Federer in the French Open. The rivalry continued as they traded wins and losses. In 2008, Nadal was able to capture the No. 1 ranking until Federer defeated him once again in 2009, regaining his number one ranking and securing another title. The two have yet to face off in 2010.

Federer has consistently improved with every year and has showed no signs of slowing down. While most tennis players play their best on one or two surfaces, Federer has dominated on all surfaces. Look for Federer to continue his winning ways in 2010, as he looks to break more records and possibly establish his place as the greatest tennis player of all time.
