On
January 4, 2007, Henin withdrew from the
Australian Open and the warm-up tournament in
Sydney to deal with the break-up of her marriage, resulting in losing the No. 1 ranking to
Maria Sharapova. In Henin's first tournament of the year, she lost in the semifinals of the
Open Gaz de France to Czech
Lucie Šafářová 7-6(5), 6-4. She then won two hardcourt tournaments in the
Middle East, the
Dubai Duty Free Women's Open (for the fourth time in five years) over
Amelie Mauresmo 6-4, 7-5, and her first
Qatar Total Open title, in
Doha, defeating
Svetlana Kuznetsova in the final 6-4, 6-2. She also reached
US$14 million in career prize money, and on
19 March regained the No. 1 ranking.
At the
Sony Ericsson Open in
Key Biscayne, Florida, Henin reached the final for the first time in her career, where she lost to
Serena Williams 0-6, 7-5, 6-3 after holding two match points at 6-0, 5-4. She then withdrew from the
Family Circle Cup in
Charleston with an ongoing respiratory problem. Her next tournament was the
J&S Cup in
Warsaw, Poland, which she won, beating
Alona Bondarenko of
Ukraine 6-1, 6-3 in the final. Later, at the
Qatar Telecom German Open in
Berlin, Henin won a marathon quarterfinal against
Jelena Janković 3-6, 6-4, 6-4 after being behind 4-0 in the third set, only to lose her semifinal against Kuznetsova 6-4, 5-7, 6-4. The loss was only her second to Kuznetsova in 16 career meetings.
At the
French Open, Henin was the two-time defending champion and top seed. In a highly anticipated quarterfinal match against Serena Williams, Henin won 6-4, 6-3. She then defeated Janković in the semifinals 6-2, 6-2. In the final, Henin defeated
Ana Ivanović 6-1, 6-2 to claim her third consecutive French Open title, equalling
Monica Seles's open era record, and surpassed US$15 million in career prize money earnings. Henin won the tournament without dropping a set.
In her first Grass Court tournament of the year, the
International Women's Open in
Eastbourne, Henin defeated each of her first three opponents in two short sets;
Agnieszka Radwańska 6-4, 6-1;
Nicole Vaidišová 6-2, 6-2 and
Marion Bartoli 6-1, 6-3. The final, against
Amélie Mauresmo, was the first Eastbourne final in nearly 30 years between the two previous Wimbledon finalists. Henin fought back from a break down in the final set to win in a third set tie-break for the second consecutive year, 7-5, 6-7(4), 7-6(2).
At
Wimbledon, Henin lost to
Marion Bartoli in the semi-finals, 6-1, 5-7, 1-6, one day after an emotional victory over
Serena Williams in the quarter-finals. It was Henin's first win over the American on a surface other than clay. In the semi-final Henin had a 6-1, 1-0 break lead, and served in the second at 4-3; she also held a 0-30 advantage against Bartoli's serve at 5-5 in the second set before squandering two break points to give Bartoli a 6-5 lead, eventually capitulating her serve to love. In the third set Henin came close to losing a "bagel" set, dropping the first five games of the decider, and seven in a row, to go 0-5. After Henin's hold to 1-5, Bartoli served out the match, in a win described as one of the biggest upsets in Wimbledon history. Henin passed $16 million in prize money after Wimbledon, to stand at 8th in all-time career prize money, ahead of compatriot Kim Clijsters.
Henin won the Rogers Cup Tier I event in August in Toronto, defeating Jelena Janković 7-6 7-5 in a tough battle between the two top seeds. At a critical juncture of the second set, tied 5-5, Henin fought off 6 break points in a row, before cruising through the final game of the match. The victory was Henin's 35th on the WTA tour, moving her past Kim Clijsters, who retired with 34 wins.
Henin was in top form during the 2007 U.S. Open championship. She defeated her first four opponents in straight sets, with a 6-0 set in each match. Justine then faced
Serena Williams in the quarters for the third time in a row in a major, and for the third time Henin emerged on top, 7-6(3), 6-1. She then defeated
Venus Williams in the semifinals 7-6(4), 6-4 in a nearly two-hour battle of superb quality. By beating Venus, Justine became only the second player in history to defeat both Williams sisters in a Grand Slam (the first was
Martina Hingis in 2001 at the Australian Open, where she beat Serena in the quarters and Venus in the semis, though she lost to
Jennifer Capriati in the final). Henin won her second U.S. Open after being denied last year against
Maria Sharapova. She defeated
Svetlana Kuznetsova, the U.S. Open champion in 2004, the final score being 6-1, 6-3. With this straight sets victory, Henin went through the entire tournament without dropping a set, like her previous French Open win. When the WTA rankings were released on
September 10th, Henin and Kuznetsova were the Top 2 players. The U.S. Open victory took Henin past the $17 million mark in career prize money.
In her next tournament, the
Porsche Tennis Grand Prix, Henin defeated
Dinara Safina, Elena Dementieva and
Jelena Janković in straight sets, before going on and winning a three set final against
Tatiana Golovin. On October 9th, Henin mathematically clinched the year-end # 1 ranking for the third time in her career, having done so previously in 2003 and 2006.
Two weeks later, Henin competed in the
Zurich Open. After a near-upset against Nicole Vaidišová in the semi-finals(3-6, 6-3, 7-5), she collected her 9th title of the year by defeating Tatiana Golovin once more (6-4, 6-4). She thus extended her winning streak since her
Wimbledon loss to
Marion Bartoli to an impressive 20 consecutive matches, and extended her lead in the rankings.
