Daniela Hantuchová (Slovak pronunciation: [ˈdaɲi̯ɛla ˈɦantuxɔvaː]; born April 23, 1983) is a Slovakian professional tennis player. She turned professional in 1999 and had her breakthrough year in 2002, when she won her first Tier I tournament and ended the year in the top 10.

She is currently coached by Larri Passos. Her WTA Tour mentor in the "Partners for Success" program was Martina Navrátilová, who was her doubles partner for a brief period in early 2005. As of May 28, 2012, Hantuchová is ranked World No. 18 in singles.

In 2005, she became the fifth female tennis player to win the mixed doubles title in all four Grand Slam tournaments during her career.

Hantuchová was born in Poprad, Czechoslovakia (now Slovakia) to father Igor, a computer scientist, and mother Marianna, a toxicologist.

When her parents split up in 2003, Hantuchová's performances temporarily worsened. At Wimbledon that year, she failed to convert several match points and was seen weeping on court. She also suffered from a weight problem during this period. She was suspected of being anorexic, but denied this.

Maria Yuryevna Sharapova (Russian: Мария Юрьевна Шарапова [mɐˈrʲijə ˈjurʲjɪvnə ʂɐˈrapəvə] ( listen), US: /ʃɑrəˈpoʊvə/, UK: /ʃærəˈpoʊvə/; born April 19, 1987) is a Russian professional tennis player and former world no. 1. A United States resident since 1994, Sharapova has won 26 WTA singles titles, including three Grand Slam singles titles at the 2004 Wimbledon, 2006 US Open and 2008 Australian Open.

Sharapova made her professional breakthrough in 2004 at age 17, when she defeated two-time defending champion and top seed Serena Williams in the 2004 Wimbledon final for her first Grand Slam singles title. She entered the top 10 of the WTA Rankings with the win. Despite not winning a major in 2005, Sharapova briefly held the no. 1 ranking, and reached three Grand Slam semifinals, losing to the eventual champion each time. She won her second major at the 2006 US Open defeating then-world no. 1 Amélie Mauresmo in the semifinals and world no. 2 Justine Henin in the final.

She is the only female player to have won over $35 million in prize money.

Her 27 Grand Slam titles places her ninth on the all-time list: 13 in singles, 12 in women's doubles, and 2 in mixed doubles. She is the most recent player, male or female, to have held all four Grand Slam singles titles simultaneously and only the fifth woman in history to do so.

Ivanovic's mother Dragana (Драгана), a lawyer, supports her daughter during most of her matches. Her father Miroslav (Мирослав), a self-employed businessman, attends as many events as he possibly can. Ana has a younger brother, Miloš (Милош), with whom she loves to play basketball.

Aside from her tennis career, Ivanovic also studies finance at a university in Belgrade and Spanish in her spare time. Her inspiration to begin playing was Monica Seles, who at that time played for Yugoslavia.

She won the 2010 French Open singles title, becoming the first Italian woman to win a Grand Slam event in singles. She was also runner-up at the 2011 French Open. As of 28 May 2012, Schiavone's ranking is World No. 12; her career high ranking is World No. 4, achieved on 31 January 2011.

Schiavone employs an all court game and has a very classic approach to her clay game. She uses an extreme eastern grip on her one handed backhand. Chris Fowler and Brad Gilbert described her forehand as a "buggy whip."

Schiavone has won four singles titles on the WTA tour, but has also achieved ten runner-ups in total, eight of them since the autumn of 2005. Schiavone lost her first eight career finals before finally winning her first title in July 2007. She and her Italian teammates Mara Santangelo, Flavia Pennetta, and Roberta Vinci beat the Belgium team 3–2 in the 2006 Fed Cup final. Justine Henin had to retire in the fifth and final match due to an injury in her right knee, which let Italy win their first Fed Cup trophy. This match was a doubles match and Kirsten Flipkens partnered Henin and Roberta Vinci partnered Schiavone. In 2009 she won the Fed Cup with Italy for the second time against the USA, and also made the quarterfinals of Wimbledon for the first time. In 2010 Italy with Schiavone won the Fed Cup for the third time.
