Roger Federer (German pronunciation: [ˈfeːdəʁɐ]) (born 8 August 1981) is a Swiss professional tennis player who held the ATP No. 1 position for a record 237 consecutive weeks from 2 February 2004 to 18 August 2008. Federer has occupied the #1 ranking for 285 overall weeks, one week short of the record 286 weeks held by Pete Sampras. As of 28 May 2012, he is ranked World No. 3. Federer has won a men's record 16 Grand Slam singles titles. He is one of seven male players to capture the career Grand Slam and one of three (with Andre Agassi and Rafael Nadal) to do so on three different surfaces (clay, grass, and hard courts). He is the only male player in tennis history to have reached the title match of each Grand Slam tournament at least five times and also the final at each of the nine ATP Masters 1000 Tournaments. Many sports analysts, tennis critics, and former and current players consider Federer to be the greatest tennis player of all time.

Federer has appeared in an unprecedented 23 career Grand Slam tournament finals, including a men's record ten in a row, and appeared in 18 of 19 finals from the 2005 Wimbledon Championships through the 2010 Australian Open, the lone exception being the 2008 Australian Open. He holds the record of reaching the semifinals or better of 23 consecutive Grand Slam tournaments over five and a half years, from the 2004 Wimbledon Championships through the 2010 Australian Open. At the 2012 Australian Open, he reached a record 31st consecutive Grand Slam quarterfinal. During the course of his run at the 2012 French Open in Roland Garros, Federer eclipsed Jimmy Connors long standing record of 233 match wins in Grand Slam tournaments when he defeated Adrian Ungur in a second round match.

Paul-Henri Mathieu (born 12 January 1982 in Strasbourg, France) is a French tennis player. His career-high singles ranking is World No. 12.

Mathieu was born in Strasbourg, France. He first began playing tennis at age 3, with his older brother Pierre-Yves. Between 1997 and 2000 he trained at the Nick Bollettieri Tennis Academy in Bradenton, Florida. After having won the Junior title at the French Open (defeating Tommy Robredo), he made his ATP tour debut in July 2000, in Kitzbühel.

2002 was Mathieu's breakthrough year. He made the 4th round of the French Open, losing to Andre Agassi in 5 sets, despite having a 2 set lead. Later on in the year, he confirmed his potential by winning back to back tournaments in Moscow and Lyon. On 14 October he became world no. 36 and his progess won him the ATP Newcomer of the Year award for 2002. He also nearly won the Davis Cup in 2002 with the French Davis Cup team, but lost the deciding rubber of the final to Mikhail Youzhny of Russia, once more after relinquishing a 2 set advantage.
