Tournament names:

German Open is a name given to many sports events established in Germany, and include:

Ana Ivanovic (Serbian Cyrillic: Ана Ивановић, Ana Ivanović; Serbian pronunciation: [âna iʋǎːnoʋitɕ] ( listen)) (born November 6, 1987, in Belgrade, SR Serbia, SFR Yugoslavia) is a former world no. 1 Serbian tennis player. As of May 28, 2012, she is ranked 14th on the Women's Tennis Association (WTA) rankings. She beat Dinara Safina to win the 2008 French Open and was the runner-up in singles at the 2007 French Open and the 2008 Australian Open. Competing as a professional since 2003, she has won 11 WTA Tour singles titles. When on form, Ivanovic is known for her aggressive style of play.

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.

Dinara Mikhailovna Safina (Russian: Динара Михайловна Сафина, Tatar: Динара Мөбин кызы Сафина, Dinara Möbin kızı Safina), born April 27, 1986 in Moscow, is a Russian professional tennis player of Tatar background. Safina's career high ranking is World No. 1.

Safina was runner up in singles at the 2008 French Open, 2009 Australian Open, and the 2009 French Open, falling to Ana Ivanovic, Serena Williams, and Svetlana Kuznetsova, respectively. She has had success at Grand Slam events in women's doubles by winning the 2007 US Open with Nathalie Dechy. She also won the Olympic silver medal in women's singles at the 2008 Summer Olympics in Beijing.

She is the younger sister of former World No. 1 men's player Marat Safin. She and her brother are the first brother-sister tandem in tennis history to both achieve No.1 rankings.

Safina was born in Moscow, Russia to ethnic Tatar parents. Her mother, Rauza Islanova, was her trainer when she was younger; while her father is director of the Spartak tennis club in Moscow. Her brother Marat is a former world No. 1 on the ATP Tour. Speaking of growing up in such a successful tennis family, Safina stated: "Being the little sister in such a big tennis family is not an easy situation. Maybe that's why it took me longer to develop. My father is very competitive, but my parents didn't put pressure on me. I wanted to find my identity. I wanted to be something by myself, like being a big player by myself. So at the beginning I was putting too much pressure on myself. But then gradually I found myself, and I learned how to do better with that situation." At age 8, Safina and her family moved to Valencia, Spain, and as a result Safina speaks fluent Spanish as well as Russian and English.

Serena Jameka Williams (born September 26, 1981) is an American professional tennis player and a former world no. 1. The Women's Tennis Association has ranked her world no. 1 in singles on five separate occasions. She became the world no. 1 for the first time on July 8, 2002 and regained this ranking for the fifth time on November 2, 2009. 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. She was also the first woman, along with sister Venus Williams, to hold all four Grand Slam doubles titles simultaneously since Martina Hingis did so in 1998. Her 13 Grand Slam singles titles is sixth on the all-time list. Williams ranks fourth in Grand Slam women's singles titles won during the open era, behind Steffi Graf (22 titles) and Chris Evert and Martina Navratilova (18 titles each). She has won more Major titles in singles, doubles, and mixed doubles than any other active player, male or female.
