David "Dudi" Sela (Hebrew: דודי סלע; born April 4, 1985, in Kiryat Shmona, Israel) is an Israeli professional tennis player.

Sela reached a career-high singles ranking of World No. 29 in July 2009. He is currently Israel's top men's singles player, ahead of Amir Weintraub.

As a 17-year-old junior, he won the 2003 French Open boys' doubles championship with his doubles partner. His peak junior rankings were No. 12 in singles, and No. 16 in doubles.

Representing Israel in the Davis Cup, his highlight has been an upset win in 2007 over World No. 7 Fernando González. In 2008 he beat World No. 5 David Ferrer in straight sets, and in 2010, he beat World No. 7 Andy Roddick in straight sets.

Sela's father Michael, a bus driver, and mother Anca, a nurse, immigrated to Israel from Romania. His family name was originally Sălăjean, but his father changed it so that it would be more easily pronounced in Israel. He grew up in the small city of Kiryat Shmona, on the Israel-Lebanon border.

At the age of two, Dudi, diminutive of David, had his hands on his first racket, and at the age of seven he began to play tennis. His tennis idols were his brother Ofer, who was a top 200 player, and the Israeli Amos Mansdorf. Sela spent hours as a junior studying tapes of Mansdorf, hoping to one day match his achievements.

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 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.

Grigor Dimitrov (Bulgarian: Григор Димитров; born May 16, 1991, in Haskovo) is a tennis player from Bulgaria. He achieved a career high ranking of World No. 52 on August 22, 2011. Dimitrov also enjoyed a very successful junior career, in which he held the World No. 1 ranking and won the boy's singles titles at the 2008 Wimbledon Championships and the 2008 US Open.

Grigor was born in Haskovo, Bulgaria as the only child of father Dimitar, a tennis coach and mother Maria, a sports teacher and former volleyball player. He first held a tennis racket, given to him by his mother at the age of three and when he was five he began to play daily. During his teenage years he lived in Paris, France while training at Patrick Mouratoglou's Tennis Academy. He speaks fluent Bulgarian and English and says his main interests are all sports, cars, computers and watches.

His first major junior coup was when, at aged 14 he claimed the U14 European title. In 2006 he won the Orange Bowl U16 boys singles and was later named the Eddie Herr International 2007 Rising Star.

Thomaz Cocchiarali Bellucci (born December 30, 1987 in Tietê), a professional tennis player, is the top ranked Brazilian tennis player. He achieved a career high ranking of #21 on July 26, 2010.

Bellucci used a string of ITF Challenger tournament victories early in 2008 to break into the top 100 rankings of the ATP World Tour as a 20-year-old. In 2009, he reached his first tour final at the Brasil Open and won his first tour title at the Swiss Open. In 2010, He won his second tour title at the Movistar Open in Chile.

Thomaz's playing style is using the heavy topspin of his big forehand to control points. He lacks outright power to produce a lot of aces, but he has excellent spin on his serve, allowing him to force his opponents off of the court which leads to him taking the offensive at the beginning of the point. His two-handed backhand is much more compact than his forehand, and is flatter, which allows him to take balls earlier on his backhand wing and drive the ball for winners. His preferred court is clay, but shows the adaptive potential to get much better at faster courts as well.

Frank Russell Dancevic (from Croatian Dančević) (born September 26, 1984) is a Canadian professional tennis.

He is now Canada No. 3 in singles.

In August 2011, Dancevic became the first men's singles player ever to qualify, in the same calendar year, for all four grand slam events.[2]

The right-handed Dancevic turned pro in 2003 and reached his career high singles ranking in September 2007 at World No. 65. A native of Niagara Falls, Ontario, he was the highest ranked men's Canadian singles player since Daniel Nestor, who was ranked World No. 61 in September 1999.

It was Fred Niemeyer whom Dancevic overtook to become, in early 2006, Canada's top-ranked singles player.
