In 2007, Sharapova reached the final of the Watson Water Champions Challenge, an exhibition tournament and warm-up for the
2007 Australian Open, where she was defeated by
Kim Clijsters 6-3, 7-6(8).
At the Australian Open, the top-seeded Sharapova defeated the 62nd-ranked
Camille Pin in the first round 6-3, 4-6, 9-7 on her fourth match point. The match was played in air temperatures that exceeded 40 °C (104 °F) and on-court temperatures that exceeded 50 °C (122 °F). In the fourth round, Sharapova defeated compatriot
Vera Zvonareva 7-5, 6-4. In the quarterfinals, Sharapova overcame the twelfth-seeded
Anna Chakvetadze 7-6(5), 7-5. She then defeated fourth-seeded Clijsters 6-4, 6-2 in the semifinals to reach her first Australian Open final and gain the opportunity to win the only
Grand Slam singles title that a Russian woman had not yet won. However,
Serena Williams, ranked No. 81 in the world, beat Sharapova easily 6-1, 6-2. Williams was the third-lowest-ranked player in the
open era to win a Grand Slam singles title.
Her next tournament was the
Pacific Life Open in
Indian Wells, California, where she was the defending champion and top seed. However, she lost to Zvonareva in the fourth round 4-6, 7-5, 6-1 after leading 5-4 in the second set.
At the
Sony Ericsson Open in
Key Biscayne, Florida, as the two-time defending finalist, Sharapova again lost easily to Serena Williams, this time in the fourth round 6-1, 6-1. In her previous rounds, she had defeated
Yung-Jan Chan of Taipei and
Venus Williams.
Sharapova was scheduled to play in the
Family Circle Cup in
Charleston, but a shoulder injury kept her off the tour and prevented her from playing in the
Fed Cup tie against Spain and the
Qatar Telecom German Open. She was scheduled to make her return to the tour at the
Telecom Italia Masters Roma in
Rome, but she had to pull out again because, as she said on her official website, she was not ready to play there even though her body was slowly getting better. She finally made her return at the
Istanbul Cup, her first clay court tournament of the year, where she lost to Frenchwoman
Aravane Rezaï in the semifinals 6-2, 6-4.
Sharapova then reached semifinals of the
French Open for the first time in her career. She defeated
Patty Schnyder in a controversial fourth round match after being down match point, then beat fellow Russian
Anna Chakvetadze in the quarterfinals. In her semifinal match she fell to
Ana Ivanović with a lopsided score of 6-2, 6-1.
At the
DFS Classic in
Birmingham, United Kingdom, Sharapova lost in the final to second seeded
Jelena Janković 4-6, 6-3, 7-5 having led 3-0 in the final set.
Sharapova had an indifferent
Wimbledon, falling victim to eventual champion
Venus Williams, in the fourth round. Sharapova was subdued by Williams' dominant serve and crashed out in straight sets, 6-1, 6-3. This was the first time she had lost in a Grand Slam fourth round since the
2006 French Open and the second time she has lost at the fourth round stage in Wimbledon, the first being at the 2003 Wimbledon Championships as a qualifier.
Sharapova was scheduled to play the
Fed Cup for
Russia in their semifinal tie against the
USA during the weekend 14-15 July. However, amid considerable controversy, she withdrew claiming that her shoulder injury that has been bothering her for most of the year is causing problems again. On
July 18, three days after Russia booked a place in the final with
Italy, team captain Shamil Tarpishchev announced that Sharapova would be ineligible from selection for
this year's tournament.
Sharapova supported [[Sochi]
2014 Winter Olympics bid, and the city was eventually chosen to hold the games, becoming the first Russian (as Russian Federation) city on doing so.
Sharapova then played her first summer hardcourt tournament, the
Acura Classic in
San Diego, California, where she was the defending champion. This was the final ever edition of the tournament, as it has now been discontinued. Heading into the tournament Sharapova was questioned for her seesaw season. Sharapova had also been questioned over her uncharacteristic shaky serves and double faults this season, but she showed no signs of that as well as she hit 9 aces in her second round match, including one that reached 113 mph (181.1 km/h). Later in the tournament, she hit one that reached 184 km/h. The problem had been aggravated by a shoulder injury. Sharapova came through to the final relatively unscathed; she had not lost more than three games in a set, and has not lost more than 5 games in a match. In the final, she faced #11 seed
Patty Schnyder and ended up winning 6-2, 3-6, 6-0, claiming her first title of the year and the 16th title of her career. (Until the loss of the second set, Sharapova had won 19 consecutive sets there).
Her next tournament was the
East West Bank Classic in Los Angeles, California. As the top seed, she had a first round bye. She faced
Eleni Daniilidou of Greece in the second round. Sharapova was leading 7-6(5), 3-1 when her opponent retired injured. She then survived a marathon against Netherland´s unseeded
Michaëlla Krajicek. Sharapova was down 2-4 in the second and was able to take the set to a tie-break, but she lost it 7-3. She then was twice a break down in the third, but eventually she prevailed 7-6(4),6-7(3),6-4 in 2 hours and 47 minutes. In the quarters she faced the number 9 seed and defending champion
Elena Dementieva, who beat Sharapova in the semis last year. Sharapova then moved into the semis after winning in straight sets 6-3 6-4 in 1 hour and 30 minutes after breaking Dementieva 5 times with Dementieva breaking her once in each set. She was scheduled to face another fellow Russian
Nadia Petrova, but she withdrew briefly before the match with a shin injury. Sharapova had already pulled out of the
Rogers Cup and faced a race against time to be fit for the
U.S. Open.
The US open draw was released on August 22nd; with Sharapova seeded #2. Sharapova was favored to reach the final due to all of the strongest opponents all being in the top half of the draw, and she breezed through her first two rounds against
Roberta Vinci and
Casey Dellacqua, dropping a total of only two games for both matches. After being seemingly invincible in the first two rounds, Sharapova dropped the first set to 18 year old Pole
Agnieszka Radwańska. She took the second set 6-1, as well as a 2-0 lead in the third. Radwańska ran off six straight games to claim the upset 6-4, 1-6, 6-2. It was Sharapova's earliest exit at a Slam since she lost in the same round at the U.S. Open three years ago to Mary Pierce (also in three sets). She had 12 double faults and a total of 49 unforced errors for the match. This was the first time since 1981 that the 2nd seed had lost before the fourth round.
When the September 10th rankings were released, Sharapova had dropped two spots to #4. It's the first time she's been out of the Top 2 since November of 2006. Also,
Svetlana Kuznetsova, who is now at a career-high #2, replaced Sharapova as the top-ranked Russian player. It was the first time Sharapova did not have this honor since the end of 2004 (where she was behind
Anastasia Myskina), with the exception of a brief period in May 2006 where
Nadia Petrova was the highest-ranked Russian player. Sharapova is currently at #7 in the Race Rankings, so she is not guaranteed yet to be one of the Top 8.
Justine Henin, Jelena Janković, Svetlana Kuznetsova and
Ana Ivanović are the first four to qualify for Madrid. Sharapova is behind
Anna Chakvetadze and
Serena Williams with the likes of
Venus Williams close behind.
On October 4th, it was announced on her official web-site that she had accepted wildcard to enter the
Kremlin Cup in Moscow, which started on October 8th. Sharapova was the #2 seed there and had a first round bye. Unfortunately, in the second round she crashed out to
Victoria Azarenka of Belarus 7-6(9), 6-2. Sharapova had six set points in the first set, including a 5-3, 40-0 on her serve, as well as 6-5, 7-6, and 9-8 during the tiebreaker. She could not convert, and it appeared to haunt her as she was broken twice in the second set to lose unexpectedly early. Despite the Kremlin Cup being hosted in her home country, Sharapova had never won two matches at one time in the past three years. Her record at the event is 2-3.
She will now head to the
Zurich Open where she is the defending champion, which begins on October 15th. She needed to have a strong showing, as the year-end championships begins in less than a month and Sharapova is only at #6 on the race. However, on October 15th, it was annonced that Sharapova had withdrawn from the event due to the continuing shoulder problems she has been suffering throughout the year. She might not play until
2008, which could cause her to drop out of the top 10.
Anna Chakvetadze later secured a berth in the Sony Ericsson Championships. Based off of the results in Linz, where
Marion Bartoli lost in the semis and
Daniela Hantuchova is currently in the finals, Venus Williams has earned herself a spot in the championships at No.7 It's the first time since 2002 that both Williams sisters were appearing together in the event.
Daniela Hantuchová beat
Patty Schnyder for the title in Linz which means that she will knock Sharapova off the No.8 spot to qualify for the
2007 WTA Tour Championships based on more events played this year, 12 for Sharapova compared to 26 for Hantuchova as well as a slight edge in points.
However, in a surprising turn of events,
Venus Williams withdrew from the championships in Madrid. This means that No.9 Sharapova was granted the final spot.
