Jelena Janković (Serbian Cyrillic: Јелена Јанковић, pronounced [jɛ̌lɛna jǎːnkɔv̞itɕ], born February 28, 1985) is a professional tennis player from Serbia. Janković is a former World No. 1 in singles, in the months following her finals appearance at the 2008 US Open. Janković's career highlights include winning the 2007 Wimbledon Mixed Doubles title with Jamie Murray, the 2010 BNP Paribas Open, the Internazionali BNL d'Italia twice, in 2007 and 2008 and the aforementioned appearance in the finals of the 2008 US Open. As of 20 June 2013 Janković is ranked No. 16.
Janković was born in Belgrade, Socialist Federal Republic of Yugoslavia, as the third child of Veselin and Snežana, both economists. She has two brothers, Marko and Stefan. She is a student at the Megatrend University in Belgrade, studying economics. However, she has put her course of study on indefinite hold as she continues to pursue her tennis career. Janković learned her first tennis skills at the Tennis Club 'Red Star'. As a nine-and-a-half year old she was introduced to tennis by her elder brother and fitness coach Marko. She was later trained at the Tennis Academy of Nick Bollettieri. As a junior she won the 2001 Australian Open and reached junior no. 1 in the world. In 2001, she started to play on the WTA Tour; she reached the second round at her first tournament at the Indian Wells Masters.
In October 2003, Janković entered the top 100 at no. 90 for the first time, after winning her first ITF title in Dubai. Three months later, Janković garnered her first top-10 win against Elena Dementieva in the first round of the 2004 Australian Open. In May, Janković won her first WTA title, a Tier V event, in Budapest, defeating Martina Suchá in the final. Following her win in Budapest, she reached no. 51 in the world. Elsewhere in her 2004 season, she defeated top-20 players Nadia Petrova (twice), Vera Zvonareva, Patty Schnyder, Elena Dementieva and Paola Suárez. Janković finished 2004 ranked no. 28 in the world.
She was ranked world no. 1 for seventeen consecutive weeks until she was overtaken by Serena Williams on February 2, 2009. She was the year-end world no. 1 in 2008, the second player in the history of the WTA tour to do this without winning a Grand Slam title, after Kim Clijsters.
Janković has reached the singles final of the US Open and the singles semifinals of the Australian Open and the French Open. In 2007, she became the first Serbian player to win a Grand Slam title when she won the Wimbledon mixed doubles title with British partner Jamie Murray.
She is one of only seven players who has defeated both Williams sisters at the same tournament, and one of three players who were world no. 1 and as a junior and a senior. Janković also enjoyed one of the longest recent unbroken streaks in the Top 10 of recent years, entering it in early 2007, and remaining there for four years and three months, before dropping out in mid-2011.
In March, at Dubai, she advanced to the final following Serena Williams's retirement in the semifinal. Janković then lost in the final to Lindsay Davenport in three sets. She made her first Tier I semifinal in Berlin, losing to Nadia Petrova. In June, she reached her first grass-court final at Birmingham, but lost to Maria Sharapova. In October, Janković reached her third final of the year in Seoul, ranked no. 17 in the world, her highest ranking at that time, losing to 16-year-old Nicole Vaidišová in straight sets. Her ranking at the end of the season eclipsed her 2004 record at no. 22.
Janković lost in the second round of the Australian Open to world no. 188 Olga Savchuk. That was the first of ten straight losses, not winning a match from late January into early May. She later said this run caused her to consider quitting tennis. Janković ended her losing streak by beating world no. 17 Elena Likhovtseva in the first round of the Internazionali BNL d'Italia in Rome, before eventually losing to Venus Williams in three sets in the quarterfinals. At the French Open, Janković reached the third round for the first time, where she lost to world no. 1 Amélie Mauresmo.
At Wimbledon, Janković defeated sixth-seeded and defending champion Venus Williams in the third round in three sets. Competing in the fourth round of a Grand Slam event for the first time, she lost to ninth-seeded Anastasia Myskina. In August, Janković reached her fifth career final and first of the year at the JPMorgan Chase Open in Los Angeles, defeating Serena Williams(ranked world no. 108 at the time after a lengthy injury lay-off) in the semifinals, before losing to third-seeded Elena Dementieva in the final. The US Open saw Janković defeat world no. 10 Vaidišová in the third round, world no. 7 and former champion Svetlana Kuznetsova in the fourth round, and world no. 5 Dementieva in her first Grand Slam quarterfinal. In the semifinals, Janković lost to world no. 2 Justine Henin in three sets, after Janković had led 6–4, 4–2. Janković argued with the chair umpire, when the umpire refused to offer an opinion as to whether a service call had been correct, suggesting that Janković use one of her electronic challenges. Janković then lost ten consecutive games.
Janković continued her strong form in the aftermath of the US Open. Of the six tournaments she played during the remainder of the year, she reached the quarterfinals at five. This included a run to the semifinals at the China Open in Beijing, defeating world no. 7 Nadia Petrova in the quarterfinals, before losing to world no. 1 Mauresmo in a third set tiebreak. Janković finished the year at a career-high ranking of world no. 12.
To begin the year, Janković won the second title of her career at the ASB Classic in Auckland, New Zealand, defeating Vera Zvonareva in the final. The following week, at the Medibank International in Sydney, Janković defeated world no. 7 and former no. 1 Martina Hingis and top-seeded Amélie Mauresmo on the way to the final, where she lost to Kim Clijsters after serving for the match. Janković's strong start to the year meant that some considered her a title threat at the Australian Open; however, she was eliminated in the fourth round by the eventual champion Serena Williams. Because of her results at these tournaments, her ranking rose to world no. 10, the first time she had been included in the top 10.
Janković reached two semifinals in the Middle East in the spring, retiring against Mauresmo due to an ankle injury at the Dubai Tennis Championships, and losing in three sets to Justine Henin at theQatar Total Open in Doha, Qatar. Janković rebounded in the clay-court season, defeating Venus Williams on a third set tiebreak in the semifinals of the Family Circle Cup in Charleston, South Carolina. She went on to defeat Dinara Safina in the final to win the first Tier I title of her career. On European red clay, after losing to world no. 1 Henin in three sets both in the semifinals of the J&S Cup in Warsaw and the quarterfinals of the Qatar Telecom German Open (failing to hold a 4–0 lead in the third set in the latter), Janković won her second career Tier I title at the Internazionali BNL d'Italia in Rome, defeating second-seeded Svetlana Kuznetsova in the final. This results meant she entered the top 5 in the world rankings for the first time. Janković was the fourth seed at the French Open and one of the favorites for the title. After registering her third consecutive victory over Venus Williams in the third round, she went on to reach the semifinals of a Grand Slam for the second time in her career, but lost there to eventual champion Henin. This improved her ranking to a new career-high of world no. 3.
On grass, Janković captured the DFS Classic title in Birmingham, beating top-seeded Maria Sharapova in the final. Sharapova led 3–0 in the third set, before Janković rallied to win the match. The next week, Janković reached the final of the Ordina Open in the Netherlands and became the first player since Chris Evert in 1974 to win 50 matches in the first half of a year. Janković, suffering from a hamstring injury, lost the final to Anna Chakvetadze. At Wimbledon, Janković was the third seed, but lost in the fourth round to the surprise eventual finalist Marion Bartoli. In the mixed doubles competition at Wimbledon, Janković teamed with doubles specialist Jamie Murray to win the title in three sets by beating the fifth-seeded team, Jonas Björkman and Alicia Molik.
During the North American summer hard-court season, Janković reached the semifinals of the East West Bank Classic in Carson, California, but lost there to fellow Serb Ana Ivanovic, having held two match points in the final set. The following week, Janković reached the final of the Tier I Rogers Cup in Toronto, where she lost to Henin on Henin's sixth match point. Janković had led 4–1 in the first set and 4–2 in the second set, but was unable to maintain her lead. At the US Open, Janković lost to Venus Williams in the quarterfinals.
Janković's form tailed off following the US Open. At the Commonwealth Bank Tennis Classic in Bali, Janković was upset in the quarterfinals by former world no. 1 Lindsay Davenport, in Davenport's first singles tournament since giving birth. The following week at the China Open in Beijing, Janković defeated Davenport, but lost in the final to Hungarian teenager Ágnes Szávay, after Janković had a match point in the second set. Janković finished the year on a six-match losing streak, losing all three of her round-robin matches on her debut at the year-end WTA Tour Championships in Madrid. She finished the year ranked world no. 3.
Janković had successful nose surgery immediately after Madrid to correct a breathing problem. The surgery prevented her from practicing for three weeks.
Olympic Committee of Serbia declared her the sportswoman of the year.
Janković lost in the semifinals of the Australian Open to eventual champion Maria Sharapova in straight sets, having defeated defending champion Serena Williams en route. In March at the Tier I Pacific Life Open in Indian Wells, California, Janković lost in the semifinals to Ana Ivanovic. The following fortnight, Janković reached her first final of the year at the Miami Masters, losing to Serena Williams in three sets.
Janković started the clay-court season by losing in the quarterfinals of both the Family Circle Cup in Charleston, South Carolina and the Qatar Telecom German Open in Berlin. Janković then successfully defended her Tier I Internazionali BNL d'Italia title in Rome, after defeating Venus Williams in three sets in the quarterfinals, receiving a walkover from the injured Sharapova in the semifinals, and defeating French teenager Alizé Cornet in the final. This was Janković's first singles title of the year. She went into the French Open among the favorites, following the sudden retirement of four-time champion Justine Henin. However, she lost to compatriot and eventual champion Ivanovic after leading by a break in the third set. Janković was the only player to win a set against Ivanovic during the entire tournament. This marked Janković's fourth defeat in four career Grand Slam semifinals. She would have become the world no. 1 had she reached the final. However, she did reach a new career-high of world no. 2 in the week following the tournament.
At Wimbledon, Janković injured her knee during her third-round match against Caroline Wozniacki. Although she won that match, it visibly hindered her during her fourth-round loss to Tamarine Tanasugarn. Janković would have become the world no. 1 had she reached the semifinals of the tournament. However, she lost to Tamarine Tanasugarn in the fourth round. Janković squandered two further opportunities to immediately take the world no. 1 position with losses in the semifinals of the East West Bank Classic in Los Angeles to Dinara Safina and the quarterfinals of the Rogers Cup in Montreal, to Dominika Cibulková. Janković did eventually replace Ivanovic as the world no. 1 on August 11, 2008. She was the 18th woman to have been ranked world no. 1 by the Women's Tennis Association, but the first woman to have done so without ever having reached a Grand Slam final and only the third woman (the others being Amélie Mauresmo and Kim Clijsters) to have become world no. 1 without first winning a Grand Slam title.
Janković's reign as the world no. 1 lasted only one week, after she lost in the quarterfinals of the Beijing Olympics to eventual silver-medalist Safina. This meant Ivanovic reclaimed the world no. 1 position. Janković was the second seed at the US Open, where she defeated Olympic gold-medalist Elena Dementieva in the semifinals to reach her first Grand Slam final. There, she lost to fourth-seeded Serena Williams. Janković would have reclaimed the world no. 1 position if she had won the event.
Janković became the world no. 1 again during the fall in the midst of winning three consecutive tournaments. At the China Open, Janković defeated Svetlana Kuznetsova in two sets to win the title. The following week, Janković played in the Porsche Tennis Grand Prix in Stuttgart, Germany, where she defeated Venus Williams in the semifinals and Nadia Petrova in the final. In the Kremlin Cup in Moscow, Janković defeated defending champion Dementieva in the semifinals before triumphing against Vera Zvonareva in the final for her third title in three weeks, the first time for a player on the WTA tour to do so since 2005. As the top seed at the year-end 2008 WTA Tour Championships held in Doha, Qatar, Janković won two of her three round-robin matches, including only the second win of her career over Ivanovic. However, she lost in the semifinals, to eventual champion Venus Williams and ended the year as world no. 1. In all, Janković lost to eventual champions at six tournaments (including three Grand Slam tournaments) during the season. Janković was later named the ITF World Champion for her performance in 2008. She won four titles during the season, the most of anyone on the tour along with Serena Williams and Safina.
The Olympic Committee of Serbia declared her the best sportswoman for the second year in a row.
Janković was seeded first at the Australian Open in Melbourne. She lost to 16th-seeded Marion Bartoli in the fourth round. Bartoli hit 34 winners, compared to Janković's 17 and won 81 percent of her first serve points, compared to Janković's 56 percent. Janković lost her World No. 1 ranking to Serena Williams as a result. Her next Women's Tennis Association event was the Open GDF Sueztournament in Paris. Janković beat Francesca Schiavone, Li Na and fifth-seeded Alizé Cornet but then lost to Amélie Mauresmo in the semifinals.
Janković was upset by Kaia Kanepi in the third round of Doha in straight sets, in what she called "the worst match of my career." She was the second-seeded player at the BNP Paribas Open inIndian Wells, California, losing in the second round to Anastasia Pavlyuchenkova. After the match, she conceded that she has been struggling with her confidence, saying "I need a lot of work."Janković then lost in the second round of the Sony Ericsson Open in Key Biscayne, Florida, to Gisela Dulko after Janković failed to hold leads of 5–2 in the second set and 5–2 in the tiebreaker.

In the final, Janković won her second title of the year, defeating world no. 1 Dinara Safina. With the win, her ranking also went back to world no. 4. Despite her good form leading up to the 2009 US Open, Janković's inconsistency continued, as she suffered a shock second-round defeat to Yaroslava Shvedova despite having match points in the third-set tie-break. Her ranking went down to world no. 8.

Her next tournament was Moscow, where she was seeded second. This tournament was her last chance to qualify for Doha. She was in a battle for the last available spot at Doha, along with Vera Zvonareva and Agnieszka Radwańska. However, things worked in her favor, as both Zvonareva and Radwańska fell in their early rounds, making Janković the last player to qualify for Doha. Janković lost her first match to Azarenka but bounced back defeating Safina and Wozniacki to clinch the first berth in her group. In her second year-end championship semifinal she lost to Venus Williams in three sets. She ended the year ranked no. 8 and with a 46–19 record.

One of the most prominent rivalries in women's tennis is the one between Janković and fellow Fed Cup team-mate and Serbian compatriot Ana Ivanovic. They have met eleven times, with Ivanovic leading 8–3 overall. Six of their eleven meetings have come at important stages of tournaments, whilst two have come at Grand Slam tournaments; Janković trails in both categories 1–5 and 0–2 respectively. Both players were touted as future top players following their breakthrough in 2007 and 2008, however, both have since underperformed on the WTA Tour and dropped out of the Top 10 in contrasting circumstances. Matches between Janković and Ivanovic are given the nickname "The Battle of Serbia". Since the end of 2008, the dominance of both players have diminished; both have only reached the quarter-finals (or better) at Grand Slam tournaments just once each: Janković at the 2010 French Open and Ivanovic at last year's US Open.
Their most important meeting to date was in the semi-finals of the 2008 French Open; the match was one of historic proportions as it would decide which of the two would become the first Serbian player, male or female, to gain the World No. 1 ranking. In a match that lasted three sets and saw one player try to gain authority over the other, Ivanovic prevailed; the result saw Ivanovic claim the World No. 1 ranking for the first time, however Janković would herself claim the ranking later that year.
The pair were involved in a long-running feud in early 2010, arising from Ivanovic's decision not to play in Serbia's Fed Cup World Group play-off against Slovakia due to her poor form at the time. They met in a controversial encounter at the Madrid Premier Mandatory tournament in May that year, in which Janković appeared to criticise and imitate Ivanovic's fist-pumping habit following a three-set victory. It was only Janković's third (and last to date) victory against Ivanovic, after previously winning in 2006 and 2008.
At Indian Wells in 2011, Janković was the defending champion, but Ivanovic defeated her in the fourth round, ending her title defence. That would be their last meeting in a WTA Tour match until the 2013 Australian Open, where Ivanovic prevailed in the third round.
They met six times in 2008 with Janković winning four of the six meetings, including three consecutive times in three consecutive tournaments during the fall. The third match in this streak was the final of the Kremlin Cup, which was the third consecutive title won by Janković in a stretch which also included titles in Beijing and Stuttgart. Janković had defeated Zvonareva on her way to the two titles which preceded the Kremlin Cup. However, Zvonareva would defeat Janković at the WTA Tour Championships later that year; this would be the start of an ongoing five-match winning streak against Janković.
Their only meeting at a Grand Slam tournament was at Wimbledon in 2010, in the tournament's fourth round. The match was important as neither player had reached the quarter-finals of the grass court Major to that point. Zvonareva won through (and eventually went on to reach the final) after Janković retired whilst trailing in the second set.
Their most recent meeting was at the Qatar Ladies Open in 2011 with Zvonareva winning in three sets. It was her fifth straight victory over Janković, dating back to 2008.
Jelena Janković and Venus Williams have met twelve times and each player has won six times. Janković leads 4–2 on clay courts and 1–0 on grass, whilst Williams leads 4–1 on hard. Their rivalry is one of the most competitive and even in women's tennis. Only three of their matches have been decided in straight sets: their first meeting in the quarter-finals of the 2005 East of the West Bank Classic, which Venus won 6–3 6–3; the second was in the quarter-finals of the 2010 Internazionali BNL d'Italia which Janković won 6–0 6–1; this was the worst ever defeat in Venus Williams' entire career, and their third and most recent meeting in the second round of the 2012 Family Circle Cup, which Venus won 7–5 6–0.
They have met three times in Grand Slams. Janković caused an upset at Wimbledon in 2006 where she defeated the defending champion in the third round, winning in three sets. They met twice at the Majors in 2007, Janković winning at the French Open, and Williams winning at the US Open in 2007. Both matches required a third set.
They have also met twice at the WTA Tour Championships, both times in the semi-finals with Williams winning in three sets on both occasions.
Jelena Janković is often regarded as a counterpuncher. Jelena is known for being able to slide effectively on all surfaces. Janković has very consistent groundstrokes and prefers to go down the line more often than crosscourt. Her weapon is her two-handed backhand. She also has a decent forehand and a fair net game, being able to hit effective drive, drop and swinging volleys. Her main weakness is her serve. She likes to spin it in on the first and second serve which can lead to her getting broken many times in matches. Her weakest surface is considered grass and her best surface is fast hard court where she can use her defense and speed to win matches.However, given the fact that six of her thirteen titles have come on clay, this could also be considered her best surface.
Janković was the subject of the 2008 autobiographical documentary, Jelenin svet (Jelena's World), featuring Justine Henin, Svetlana Kuznetsova, Ana Ivanovic, Elena Dementieva and other notable players.
On December 5, 2007, Janković became a UNICEF National Ambassador for Serbia, for Children's Fund. "I am happy to have become a UNICEF ambassador for Serbia. This is a great honour for me and I will try to justify the role that has been given to me", she said. Janković is the second Serbian tennis star to have volunteered to help promote the rights of children and collect funds for UNICEF after Ana Ivanovic became an ambassador in September.
Janković is currently sponsored by Italian sportswear company Fila. Before Janković had endorsed Anta and Reebok sportswear, and had her own line with them for her tournament wear. Janković also has an endorsement with Prince Sports and now uses the Prince O3 Speedport Pro White Racquet after formerly using the Prince O3 Red Racquet. She now uses the Prince EXO3 Black.
