Florian Mayer (born 5 October 1983) is a German professional tennis player. He plays on both the ATP Tour and the Challenger Tour.

Mayer reached his career-high singles ranking of World No. 18 on 6 June 2011. Also in 2011, Mayer won his first ATP title after four previous defeats in ATP finals. In addition, he has won nine Challenger events.

At the 2004 Wimbledon Championships, Mayer reached the quarter-finals, which is his best Grand Slam result to date. He received the ATP Newcomer of the Year award in 2004.

Florian made a return from injury reaching the final of the Nouméa Challenger but losing to Brendan Evans. Mayer then qualified for the main draw of the Australian Open by beating Sergei Bubka, Blaž Kavčič and Amer Delic.

Tommy Haas (born 3 April 1978 as Thomas Mario Haas) is a German and recently naturalized American professional tennis player. He has competed on the ATP Tour since 1996. After breaking into the World Top 100 in 1997, and reaching a career-high singles ranking of World No. 2 on 13 May 2002, Haas's career has been interrupted by injuries: whilst a professional, he has twice dropped out of the world rankings due to being inactive for twelve months. His first period of injury saw him miss the whole of the 2003 season, and he did not return to the world's top ten until 2007. He also missed over a year's tennis between February 2010 and June 2011, but has since returned to play on the Tour.

Haas has never won a Grand Slam tournament, his best result being three-time semi-finalist at the Australian Open and one semi-final at Wimbledon. He has won thirteen career titles in singles and doubles, including one Masters tournament, and has a silver medal from the 2000 Summer Olympics.

His equipment include Solfire, Lacoste and Nike for his clothes and shoes, respectively. He switched to using Head racquets in 2009 after using Dunlop Sport racquets for most of his career.

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.

Tsonga eventually lost to the then world no. 3 Novak Djokovic in the final in four sets, after winning the first set, the only set Djokovic dropped during the tournament.
