The senior Dolgopolov was also the coach of Andrei Medvedev, Ukraine's most successful tennis player to date. At a young age, Dolgopolov lived on the tour with his parents, traveling frequently and playing players such as Medvedev, Andre Agassi, and Boris Becker. Players such as Jim Courier remembered hitting balls with Dolgopolov when he was a toddler.

Dolgopolov made his ATP Tour debut in September 2006 at the BCR Open Romania as a qualifier, losing in the first round to Christophe Rochus. He was also part of the Ukrainian Davis Cup team in the tie against Great Britain, where he was defeated by Andy Murray.

Milos Raonic ( /ˈmiːloʊʃ ˈraʊnɪtʃ/ MEE-lohsh ROW-nich;Serbian: Милош Раонић, Miloš Raonić [mîloʃ râonitɕ]; born December 27, 1990) is a Canadian professional tennis player who lives in Thornhill, Ontario, Canada.

In 2011 he rose from World No. 152 to No. 37 in a month, after he reached the fourth round of the Australian Open and won his first ATP title at the 2011 SAP Open. Raonic, who prefers to play on hard courts, plays an all-court game but is most notable for his serve, which is powerful and accurate. Since late 2010 he has been coached by former Spanish pro player Galo Blanco in Barcelona.

Raonic's first ITF-sanctioned junior tennis event was the qualifying draw for the Canadian ITF Group 4 Championships in October 2003, where he lost in the first round to fellow Canadian Kirill Sinitsyn 6–7, 3–6. His next junior circuit action was a year later at the Canadian ITF Championships 1 event, where he lost in the first round of the main draw 4–6, 4–6 to compatriot Peter Marrack. In doubles at the same event he and partner Sheharyar Wali, also Canadian, reached the second round.

As of 28 May 2012 (2012 -05-28)^[update], he is ranked No. 2 by the Association of Tennis Professionals (ATP). He is widely regarded as one of the greatest players of all time; his success on clay has earned him the nickname "The King of Clay", and has prompted many experts to regard him as the greatest clay court player of all time.

Nadal has won ten Grand Slam singles titles, including a record six French Open titles (tied with Bjorn Borg), the 2008 Olympic gold medal in singles, a record 21 ATP World Tour Masters 1000 tournaments, and also was part of the Spain Davis Cup team that won the finals in 2004, 2008, 2009 and 2011. He completed the Career Grand Slam by winning the 2010 US Open, being the seventh player in history, and the youngest in the open era, to achieve it.

Gilles Simon (born December 27, 1984) is a French professional tennis player and former world no. 6. He is a ten-time winner on the ATP World Tour. His coach is French tennis veteran Thierry Tulasne, and his fitness trainer is Paul Quetin.

Simon was born in Nice, France, into a family with no involvement in sport, his mother being a doctor and his father working in insurance. Supported by his parents, he started playing tennis at the age of 6. Due to a growth delay that runs in the family, he was shorter than most kids his age during his early teenage years. This is the reason he cites Michael Chang as a major influence, as his comparatively small frame proved that size was not an important factor in playing tennis.

On September 2, 2010, Simon became a father for the first time. His partner Carine Lauret gave birth to a baby boy. The couple named their first child Timothée. Timothée was born four weeks ahead of schedule, when Simon was competing in the 2010 US Open.

Simon began his professional tennis career in the summer of 2002, competing at multiple Futures tournaments in France before playing in tournaments outside the country of his birth. His first Futures title came in Lisbon, Portugal, in June 2003, and he reached the quarterfinals of three other tournaments. He then captured his second title in Jamaica in September. During 2004, he saw three wins in France and another in Algeria.
