Nenad Zimonjić

Zimonjić turned pro in 1995 and remained relatively unknown outside his native country until a surprise victory in the mixed doubles at the 2004 Australian Open. Paired for the first time with Russian Elena Bovina, he beat defending champions Martina Navratilova and Leander Paes in straight sets in an hour and nine minutes. Alongside Katarina Srebotnik of Slovenia, he won the 2006 French Open crown with a straight-sets victory over Daniel Nestor and Elena Likhovtseva. At the 2006 Wimbledon Championships, Zimonjić reached the final of the men's doubles alongside France's Fabrice Santoro and the quarterfinals of the mixed doubles.

In 2007, Zimonjić reached the 2007 French Open mixed doubles final as the defending champions with Katarina Srebotnik and lost to Nathalie Dechy and Andy Ram. He left Santoro after Wimbledon and teamed with Mahesh Bhupathi until after the 2007 US Open. After the US Open, Nenad left Bhupathi and partnered with Daniel Nestor,[4] who won the French Open earlier in the year alongside Mark Knowles. The team won the 2007 St. Petersburg Open, without losing a set. Nestor and Zimonjić later won 2008 Wimbledon[5] (Zimonjić's first Grand Slam), 2009 Wimbledon and 2010 French Open.

In 2009, they defended their Wimbledon title & won 5 Masters 1000 titles. At the World Team Cup as a part of the Serbian team. With Victor Troicki, he won two decisive games against Italian and Argentinian teams; as a result, Serbia finished first in its group, and then proceeded to beat Germany in the final encounter.

In 2010, they finished runners-up at the Australian Open, later on in the year he won both the doubles with Daniel Nestor and the mixed doubles with Katarina Srebotnik at Roland Garros. Zimonjic ended his partnership with Nestor after winning the ATP World Tour Finals.

In 2011, he partnered with Michaël Llodra, with whom he won one Masters 1000 title & four ATP 500 titles. Their partnership ended mid-way through 2012, after Roland Garros. In 2014, Zimonjic & Nestor renewed their partnership, which saw them both return to the top 10 by May & ranked 3 by the end of the year. In 2015 he started the year partnering Aisam-ul-Haq Qureshi, then teamed up with Marcin Matkowski; despite not winning a title together, the Polish-Serbian duo qualified for the World Tour Finals. Zimonjic won titles each year for 16 straight seasons and finished 12 consecutive seasons, starting in 2004, ranked in the ATP doubles top 20. Since 2016, when he played doubles at the Rio Olympics with Novak Djokovic, Zimonjic hasn't had a steady partner for a full season.

On 26 July 2017 the Serbian became the 10th player to record 700 doubles match wins (or more).[6]

In June 2018, Zimonjic underwent bilateral hip replacement surgery.[7] He returned to the ATP tour in February 2019 at the Sofia Open, where he and compatriot Viktor Troicki had won the doubles title two years prior.

In August 1994, Zimonjić won his first professional singles title, beating Miles MacLagan on clay at a satellite tournament in Hungary. He went on to win four other ITF satellite events, as well as four Challenger tour titles in singles: Kiev (Ukraine) in 1998, Belo Horizonte (Brazil) in 2000, Andrezieux (France) in 2001, and Belgrade (Serbia) in 2004. In 2004, he defeated Andre Agassi in St Pölten, and in 2005 on the grass of Halle, he defeated Nicolas Kiefer. Other recognised opponents include Ivo Karlovic in 2000, Nicolas Mahut in 2001.

Zimonjić has been a member of Serbia Davis Cup team (previously Yugoslavia Davis Cup team and Serbia and Montenegro Davis Cup team, respectively) since 1995, playing both singles and doubles, and in 2003–2004 he was the playing captain of the national team. In recent years, with the emergence of highly ranked Serbian singles players Novak Djokovic, Janko Tipsarević, and Viktor Troicki, Zimonjić became a doubles specialist on the team, partnering all of them, as well as Dušan Vemić and Ilija Bozoljac.

In 2010, Serbia won its first ever Davis Cup title, following the victories over United States (3–2), Croatia (4–1), Czech Republic (3–2), and France in the final match (3–2). Zimonjić played in all four doubles rubbers over the course of the competition, winning once (against Croatia, partnering Tipsarević) and losing the other three times (partnering Tipsarević, Djokovic, and Troicki, respectively). To celebrate the win, all the players shaved their heads. The central celebration was held in Belgrade in front of several thousand fans, and the Serbian national postal service issued a stamp picturing the players.[8]

In the 2013 quarterfinals against the United States, he and Ilija Bozoljac had an impressive five set victory against the no. 1 ranked Bryan brothers.[9]
