Robin Bo Carl Söderling (Swedish pronunciation: [ˈrɔbɪn ˈsøːdəɭɪŋ]; born 14 August 1984 in Tibro) is a professional tennis player from Sweden who is currently ranked number 67 in the ATP rankings. Söderling reached successive French Open finals in 2009 and 2010. In both tournaments, he defeated the defending champion and number 1 seed en route to the final — Rafael Nadal in 2009 (becoming the first and, to date, only player to defeat Nadal at the French Open), and Roger Federer in 2010 (ending Federer's record streak of 23 consecutive Grand Slam semifinals). He has also won one Masters 1000 event, the 2010 Paris Masters.

Söderling speaks English, Swedish and a bit of German. His father Bo is a lawyer and mother Britt-Inger, a housewife. Söderling's sister, Sandra, is a teacher. He is engaged to Jenni Moström. The couple are expecting their first child in late-September 2012.

Söderling began playing tennis at the age of five. He made his first steps in international tennis in November 1998 in Luxembourg when at the age of 14 he played his first official junior tournament, losing the opening match to Fred Hemmes, Jr. In his first full year in the junior tour (2000), he achieved four tournament victories and in 2001 attained three more titles in the juniors including the Orange Bowl. In the same year Söderling achieved fourth place in the year-end ranking and played in his first ATP tournament in Stockholm, winning his first match 6–3 6–3 against Ramón Delgado.

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.
