Roger Federer (born August 8, 1981) is a Swiss tennis professional, currently ranked World No. 1, whose achievements rank him among the most successful players of all time. Many observers, including many of his peers, believe he may prove to be the greatest player ever.
In 2004, Federer became the first man since Mats Wilander in 1988 to win three out of the four Grand Slam singles tournaments in the same year. In 2006, Federer repeated this feat and became the first man in the open era to win at least ten singles championships in three consecutive years. He has won nine Grand Slam men's singles titles in 30 appearances, three Tennis Masters Cup, and 12 ATP Masters Series singles titles. He is the only player to have won both the Wimbledon and U.S. Open singles titles in three consecutive years (2004-2006).
He has been ranked No. 1 since February 2, 2004. His current lead in the rankings guarantees that on February 26, 2007, he will break the record for most consecutive weeks as the top-ranked male player
