Radek Štěpánek ((Czech pronunciation: [ˈradɛk ˈʃcɛpaːnɛk]; born 27 November 1978 in Karviná) is a professional tennis player from the Czech Republic. His career-high singles ranking is World No. 8.

Štěpánek turned professional in 1997. He started on tour as a doubles specialist, winning 12 ATP titles. Since 2002, Štěpánek has focused on being a better singles player while still playing top-level doubles. He is known for his after-the-shot grunting, his over-the-top celebrations and his many relationships with WTA players.

Štěpánek first came to mainstream notice when he defeated former world No. 1 Gustavo Kuerten in five sets on his way to the third round of the 2003 Australian Open.

2006 was Štěpánek's best year to date; he found himself on the verge of getting into the top ten of ATP rankings, as he defeated José Acasuso in the semi-finals of the Masters Series event in Hamburg. He went on to lose the final in straight sets against Spain's Tommy Robredo. At that point, he achieved a career-high ATP world ranking of No. 11 in singles.

Andrew Stephen "Andy" Roddick (born August 30, 1982) is an American professional tennis player and a former World No. 1. He is currently the third highest-ranked American player, behind Mardy Fish and John Isner.

He became a Grand Slam singles champion when he won the title at the 2003 US Open, defeating Juan Carlos Ferrero in the finals, which currently makes him the last North American male player to win a grand slam singles event. Roddick has reached four other Grand Slam finals (Wimbledon in 2004, 2005 and 2009, and the US Open in 2006), losing to Roger Federer each time. He is married to Brooklyn Decker, a Sports Illustrated swimwear model and actress.

Roddick was born in Omaha, Nebraska to Jerry and Blanche Roddick. Roddick's father was a businessman and his mother was a school teacher. She now directs the Andy Roddick Foundation. Roddick has two older brothers, Lawrence and John (All-American tennis player at University of Georgia (1996–98) and head tennis coach at the University of Oklahoma), who were both promising tennis players at a young age.

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.
