Hingis started 2007 by reaching the final of a Tier III event, the Australian Hardcourt Championships in
Gold Coast, Australia, losing to
Dinara Safina of
Russia 6-3, 3-6, 7-5. The next week at the
Medibank International in Sydney, Hingis lost her first round match to
Jelena Janković in three sets.
At the
2007 Australian Open, Hingis won her first three rounds without losing a set before defeating
China's Na Li in the fourth round 4-6, 6-3, 6-0. Hingis then lost a quarterfinal match to
Kim Clijsters 3-6, 6-4, 6-3. This was the second consecutive year that Hingis had lost to Clijsters in the quarterfinals of the Australian Open and the third time in the last five
Grand Slam tournaments that Clijsters had eliminated Hingis in the quarterfinals.
Hingis won her next tournament, the Tier I
Toray Pan Pacific Open in
Tokyo, Japan, defeating
Ana Ivanović in the final 6-4, 6-2. This was Hingis's record fifth singles title at this event.
Three weeks later, Hingis lost for the second time this year to Janković in the quarterfinals of the
Dubai Duty Free Women's Open. At the
Qatar Total Open in
Doha, Hingis lost to
Daniela Hantuchova 1-6, 6-4, 6-4 in the quarterfinals after being up a set and 4-1 (40-0) in the second set. In women's doubles, Hingis teamed with
Maria Kirilenko to win the title, defeating
Agnes Szavay and
Vladimira Uhlirova in the final 6-1, 6-1.
At the
Pacific Life Open in
Indian Wells, California, which was the second Tier I tournament of the year, Hingis again lost to Hantuchova, this time in the fourth round 6-4, 6-3. Hingis was up a service break in both sets but, as in Doha, could not hold her lead.
At the Tier I
Sony Ericsson Open in
Key Biscayne, Florida, Hingis again failed to reach the quarterfinals, losing in the third round to
Agnieszka Radwańska of
Poland 4-6, 6-3, 6-2.
Her next tournament was the
Qatar Telecom German Open, where she fell in the third round to compatriot
Patty Schnyder 6-4, 6-0. A hip injury that troubled her at the German Open (she took painkillers for her matches) caused her to withdraw from the
Telecom Italia Masters Roma, where she was the defending champion, and the
French Open, the only Grand Slam singles title that has eluded her.
In her first round match at
Wimbledon Hingis saved two match points to defeat British wildcard
Naomi Cavaday. Afterwards it emerged Martina had not fully recovered from the hip injury that prevented her from playing in Roland Garros. In the third round Hingis lost to
Laura Granville of the United States 6-4, 6-2 and claimed afterwards she should not have entered the tournament. In San Diego, Martina defeated Michaella Krajicek 7-5 6-2 before falling to an in-form Patty Schnyder 6-1 6-7(4) 6-3. Hingis was leading 3-1 in the final set before losing 5 straight games.
In August 2007, Hingis lost to
Sania Mirza 6-2, 2-6, 6-4 in a second-round match of East West Bank Classic WTA Tournament.
Her next tournament was the last grand slam of the year, the
U.S. Open, the same Open that she won exactly ten years ago for the first time. Fortunately for Hingis, she got stuck in the bottom, less competitive part of the draw. After winning in the first two rounds, many commentators had been saying that if she continued to play the way she was, she had a chance of making the semi-finals with her variety of shots instead of the hard hitting players that make up most of the womens tour. If she won in the third round, her likely opponent would have been fourth seeded, and 2004 champion,
Svetlana Kuznetsova, who has been known to be great when she plays well, but very inconsistent. With the recent exit of last years champion and number two seed,
Maria Sharapova, the bottom half had been blown wide open, with anyone having a chance to make the finals, including Hingis.
Unfortunately, Hingis crashed out of the third round losing to Belurusian Teenager Victoria Azarenka 6-3,1-6,0-6; however, she will gain points for improving by one round from her shock second round exit last year.
In September 2007, Hingis played at her debut tournament in Beijing. She had a comfortable first round win over Chinese youngster Tian Tian Sun 6-2,6-3; however, her winning form was halted when she lost in the second round to Chinese star Shuai Peng in straight sets 7-5,6-1.
Hingis' next tournament was due to be in Stuttgart for the Porsche Grand Prix but pulled out allegedly due to a recurrence of her hip-injury that has plagued her through the 2007 season and now causing speculation has to whether her career could soon be over permanently. The Swiss Miss was due to play her home country tournament in Zurich starting October 15th, a tournament she won in 2000, but has since withdrawn and chosen to end her season early to recover from her injury.
