She again teamed up with Nagyová in the doubles, reaching the third round.

Hantuchová reached her second semifinal of the year at the Birmingham Classic in June.

Daniela Hantuchová

Hantuchová started the year as the world No. 38 at the Gold Coast Hardcourts, where she lost to Justine Henin in the second round. At the Adidas International, Hantuchová was knocked out in the second round by Meghann Shaughnessy and went on to play at the Australian Open. In the singles, she was seeded 32nd and lost in the third round to second seed Venus Williams. In the doubles, she and partner Arantxa Sánchez Vicario were seeded thirteenth and reached the final, where they lost to Martina Hingis and Anna Kournikova. In the mixed doubles, she and partner Kevin Ullyett also reached the final, where they beat Gastón Etlis and Paola Suárez, securing Hantuchová her second Grand Slam title in as many years.

At the Open Gaz de France and the Proximus Diamond Games, Hantuchová lost in the second round, to Francesca Schiavone and Dája Bedáňová, respectively. In March, she went into the Indian Wells Masters ranked world No. 25, defeating Tatiana Poutchek, Barbara Schett, Justine Henin, Lisa Raymond, and Emmanuelle Gagliardi en route to the final, where she beat world No. 4, Martina Hingis. It was her first WTA tournament win and she was the lowest-ranked player to ever win the event.[21] She also reached the semifinals of the doubles, where she and Arantxa Sánchez Vicario lost to eventual champions Lisa Raymond and Rennae Stubbs. The following month at the Miami Masters, the Amelia Island Championships and the Family Circle Cup, Hantuchová lost in the second round, to Cara Black, Janette Husárová, and Mary Pierce, respectively. She had more success in the doubles. Continuing her partnership with Vicario, they won at Amelia Island and reached the semifinals of the Family Circle Cup.

Hantuchová then reached successive singles quarterfinals in Hamburg and Berlin, losing to Martina Hingis and Anna Smashnova, respectively. She and Vicario reached the doubles final of both, losing in Hamburg to Martina Hingis and Barbara Schett and in Berlin to Elena Dementieva and Janette Husárová. At the Italian Open, Hantuchová lost in the first round to Anastasia Myskina. She then entered the French Open as the 11th seed, losing to former champion Monica Seles in the fourth round. In the mixed doubles, she and Kevin Ullyett reached the quarterfinals. In June, she played at the Eastbourne International, reaching the semifinals in the singles and the doubles. At Wimbledon, she again reached the singles quarterfinals, only to be beaten by the eventual champion, Serena Williams. In the doubles, she partnered with former world No. 1, Jennifer Capriati, but they lost in the second round. In the mixed doubles, she and Ullyett reached their second Grand Slam final of the year. This time, they were unsuccessful, losing to Mahesh Bhupathi and Elena Likhovtseva.

Her US Open Series was modest, as she lost in the second round of San Diego and Los Angeles, after having first-round byes in both tournaments. She reached the semifinals of the Tier-I-event in Montreal, losing to Amélie Mauresmo, and New Haven, losing to world No. 2 Venus Williams. At the final Grand Slam of the year, Hantuchová defeated 1997 French Open champion Iva Majoli in round three, and world No. 6 Justine Henin, only to be beaten in her second consecutive Grand Slam quarterfinal by Serena Williams (who again went on to win the title).

Later that year, Hantuchová also reached the quarterfinals in Leipzig and the final in Filderstadt, losing to Kim Clijsters. The second set was the only set Hantuchová had taken from Clijsters in their nine meetings. She then went on to reach the quarterfinals of Zurich, losing to eventual champion Patty Schnyder in three tight sets, and the semifinals in Linz, and winning both of her singles rubbers in the Fed Cup final. This impressive season amassed her enough points to compete at the annual Tour Championships, losing in the first round to 17th ranked Magdalena Maleeva. Hantuchová's record for the year was 56–25 and 6–10 against top-10 players; 6–2 in singles Fed Cup play; 10–6 on indoor carpet, 6–2 on grass, 11–7 on clay, and 29–10 on hardcourts.

Hantuchová started 2003 solidly, reaching the quarterfinals at her first three events in Sydney, losing to Lindsay Davenport, Venus Williams, at the Australian Open (her third Grand Slam quarterfinal in a row), and Elena Dementieva in Paris. Hantuchová reached her first semifinal of the year at her fourth event in Antwerp, losing to Williams again. By then, Hantuchová's ranking was at a career-high No. 5. Defending a title for the first time in her career, Hantuchová advanced to the fourth round in Indian Wells, losing to Amanda Coetzer. Despite a first-round loss to Alicia Molik in Miami, Hantuchová rebounded in the Tier-I Charleston event, making her fifth quarterfinal in seven events, losing to Ashley Harkleroad. She made her sixth quarterfinal at her next event in Amelia Island, losing to eventual champion Dementieva. Hantuchová went undefeated in first-round Fed Cup play against Germany, winning both of her matches. Following the Fed Cup, she again made it to the quarterfinals for the seventh time of the year at the Tier-I Berlin tournament, losing to Kim Clijsters.

Hantuchová at Eastbourne in 2004

At the French Open, Hantuchová lost in the second round in a marathon match to Harkleroad again, making 101 unforced errors, leading to long-time coach Nigel Sears criticising her attitude publicly.[22] Following the match, her extremely thin physique was noticed for the first time publicly, and some wondered about Hantuchová's health. Kicking off the grass season in Eastbourne, Hantuchová lost in the quarterfinals to Conchita Martínez, but more famously she lost in the second round of Wimbledon to Shinobu Asagoe, with Hantuchová breaking down crying during the latter stages of the match and making 57 unforced errors. Some theorized that the media's continued interest regarding her weight and the pressure of success at 19 years of age, in addition to her on-court breakdown and her parents' divorce, as well as her coach's walking out in the middle of the match, led to this breakdown. Following Wimbledon, Hantuchová went 6–8 for the rest of the year, 0–4 against top-ten players She ended the year with an overall record of 28–23, and she fell to No. 17 in the world. Further signs of the pressure and problems she was facing during this period was that, in July, she made herself unavailable for Slovakia in the Fed Cup in order to concentrate on her singles career, and in November she parted company with Sears.[23]

2004 proved to be a continuation of Hantuchová's poor second half of 2003, with many of the same struggles (she briefly hired Harold Solomon, who had previously coached her friend Jennifer Capriati, as well as Anna Kournikova, before re-hiring Sears in March),[24] She reached just three quarterfinals, the first at the first Tier-I event in Tokyo was not until halfway through the season. At Tokyo, however, she garnered her thus far only victory over Maria Sharapova in the second round, falling to Davenport in the quarterfinals. The tournament that saved her from a poor 2004 was Eastbourne, in which she defeated Sugiyama in the quarterfinals, and Mauresmo in the semifinals, before losing to Kuznetsova in the third final of her career. However, Hantuchová was serving for the championship, up 6–2, 6–5, but was broken.

Hantuchová practicing during the Australian Open in 2005

Hantuchová was ranked No. 54 as she entered Eastbourne, but found herself ranked No. 38 as she went into Wimbledon, losing to eventual champion Sharapova in the third round. Hantuchová made one more quarterfinal at New Haven, losing to Lisa Raymond. At the US Open one week later, Hantuchová lost in three sets to Patty Schnyder in the third round. She finished the year ranked no. 31, with a 24–24 win–loss record. She finished 1–4 against top-10 players overall, the sole victory over Mauresmo.

Hantuchová reached the third round of the Australian Open, losing to Dementieva in a tight three-setter. Following that, she made her first quarterfinal of the year in Tokyo for the second straight year, losing to Kuznetsova. At her next event, she reached the semifinals in Doha, losing to Sharapova. Then, she made another quarterfinal at her next tournament in Dubai, losing to Serena Williams. At Dubai also, in the first round, she garnered her tenth top-10 victory over No. 8 Alicia Molik. Hantuchová made the third round at the French Open and Wimbledon, losing to Clijsters in Paris, and eventual champion Venus Williams in England.

Hantuchová had a successful US Open series run, where she reached the semifinals in Cincinnati, getting upset by No. 74 Akiko Morigami. In Stanford, Hantuchová lost to Clijsters in the quarterfinals. After a second-round loss in San Diego to Sugiyama, Hantuchová reached her fourth final in Los Angeles, getting a walkover in the quarterfinals over Sharapova, and got revenge against Dementieva in the semifinals. In the final, for the seventh time in their head-to-head, Clijsters defeated Hantuchová in straight sets. For the third time at the event, Hantuchová made the quarterfinals in New Haven, before losing to Davenport.

Hantuchová at the Zurich Open in 2006

Hantuchová lost to eventual quarterfinalist Venus Williams in the third round at the US Open. She won the mixed doubles, completing a career grand slam in mixed doubles. She has largely retired from the mixed doubles since then, saying that she "felt like it's time to move on and focus on my singles."[14] In Luxembourg, Hantuchová made her eighth quarterfinal of the season, losing to Nathalie Dechy. In Filderstadt the following week, Hantuchová made the semifinals, her third of the year, defeating No. 10 Patty Schnyder in the second round and Flavia Pennetta in the quarterfinals. She lost to Davenport in the semifinals. At the final Tier-I event of the year, Hantuchová pushed Davenport to three sets and had match points in the second set in Zurich, before losing. In her final event of the year, in Linz, Hantuchová made her tenth quarterfinal, losing to Schnyder. Hantuchová finished 2005 with a 3–10 record against the top 10, 37–25 overall record, with 2–1 on indoor carpet, 3–4 on clay, 2–3 on grass, and 30–17 on hardcourts, reaching ten quarterfinals, three semifinals, and one final.

Hantuchová reached the quarterfinals of Sydney in 2006 with a win over top-ten player Patty Schnyder and got to the semifinals of Auckland. She continued this form at the Australian Open with her third-round victory over defending champion and seven-time Grand Slam winner Serena Williams, who had entered the tournament with a lack of match practice and questions over her fitness. This victory (the only over Serena in her career) ensured that Hantuchová would progress to the fourth round of a Grand Slam tournament for the first time in three years. She lost to fourth-seeded Maria Sharapova in straight sets in the fourth round.

Hantuchová with doubles partner Ai Sugiyama at the French Open in 2006

Thereafter, she was unable to find a consistent level of form. Prior to the clay-court season, she parted company for a second time (and permanently) with Sears.[25] He was replaced by Angel Giminez. She then played her first Fed Cup matches for Slovakia in almost three years. It was a successful return, with Hantuchová winning both her singles and her doubles matches against Luxembourg, her singles match against The Netherlands, and the decisive singles rubber in the tie against Great Britain. With the help of Hantuchová's 4–0 record, Slovakia booked a place in the World Group II play-off against Thailand.

Despite disappointing results in the warm-up tournaments, she reached the fourth round of both the French Open and Wimbledon, before extending her 2006 Fed Cup record to 6–0 by winning both her singles matches in Slovakia's 5–0 rout of Thailand, which ensured their promotion to the World Group II. Her fourth-round streak at Grand Slams ended when she was beaten by a resurgent Serena Williams in the second round of the US Open, which was the culmination of a very disappointing American hardcourt season (her record was 7–6 including the US Open, failing to get past the round of 16 of any of the tournaments she entered).

Hantuchová beat Tatiana Golovin in straight sets, before losing to Dinara Safina. The following week, she reached the quarterfinals of Stuttgart with an easy victory over the then top-ten player Safina in the second round. This was both her first victory over a top-ten player and first appearance in a quarterfinal since January. In October 2006, Hantuchová reached the final of the Zurich Open. In the first round, she upset sixth seed Patty Schnyder. In the second round, she defeated her doubles partner Ai Sugiyama. Hantuchová was then scheduled to play world No. 1 Amélie Mauresmo in the quarterfinals. However, Mauresmo withdrew due to a right shoulder injury. In the semifinals, Hantuchová upset world No. 4 Svetlana Kuznetsova to reach the final of the Tier-I event. In the final, Hantuchová lost in a three-setter to second seed Maria Sharapova. The results in this tournament were the culmination of Hantuchová's up-turn of form, which kept her in the top 20, as she had arrived in Zurich outside the top group for the first time in over 11 months. The injury she suffered to her right rib[26] after Mary Pierce hit a shot at her in doubles, caused her the most serious injury of her career and also forced her to retire in her match against Vesnina the following week in Linz. Hantuchová finished the year ranked No. 17 in the world, with a 34–25 record. She went 24–17 on hardcourts, 5–4 on clay, 3–2 on grass, and 2–2 on carpet. She was 4–6 against top-10 players, beating Schnyder twice, Safina, and Kuznetsova, with losses to Sharapova (twice), Clijsters, Henin-Hardenne, Dementieva, and Nadia Petrova.

Hantuchová at the 2007 Luxembourg Open

Hantuchová's first tournament of the year was at the Auckland Open, where she lost in the second round to Virginie Razzano. Hantuchová then lost to Nicole Vaidišová in the first round of the Tier-II Sydney International and reached her second consecutive Australian Open fourth round, where she lost to world No. 5, Kim Clijsters.

Hantuchová was then upset in the first round of the Tier-I Pan Pacific Open in Tokyo by Roberta Vinci. Three weeks later at the Tier-II Dubai Championships, Hantuchová defeated Maria Kirilenko in the second round, before losing her quarterfinal match against Amélie Mauresmo in three sets. The following week at the Tier-II Qatar Open, Hantuchová trailed world No. 6, Martina Hingis, in their quarterfinal match 4–1 in the second set, before coming back to win. She then lost her semifinal match against world No. 5, Svetlana Kuznetsova. In her seventh tournament of the year, Hantuchová won six matches, the last four of which were upsets of higher seeded players, to win the Tier I Indian Wells Open. She upset Hingis in the fourth round, Shahar Pe'er in the quarterfinals, Li Na in the semifinals, and Kuznetsova in the final in straight sets.[7]

Hantuchová, however, struggled in her next four events. She was upset in the third round of the Tier I Miami Open in Key Biscayne by Vera Zvonareva. On clay at Amelia Island, Hantuchová lost to Sybille Bammer in the quarterfinals. Two weeks later, Hantuchová lost both of her Fed Cup matches against the Czech Republic in Bratislava on clay, losing to Vaidišová and Lucie Šafářová.

The following week at the Tier III Ordina Open in 's-Hertogenbosch, Hantuchová defeated world No. 6 Ana Ivanovic in the quarterfinals, before losing to Chakvetadze in the semifinals.

She then defeated Slovenian Katarina Srebotnik in the third round, before losing to world No. 8 Serena Williams in the fourth round. Immediately after Wimbledon, Hantuchová helped Slovakia win its Fed Cup World Group II play-off against Serbia. On an indoor hardcourt in Košice, she beat Ana Timotić and Vojislava Lukić.

Hantuchová at the 2007 Bank of the West Classic

Hantuchová played five tournaments during the North American summer hard-court season. She began the US Open Series by losing to Chakvetadze in the semifinals of the Tier-II Stanford Classicn. This result put her back in the top ten. At the Tier-I San Diego Classic, she lost to world No. 16, Venus Williams, in the second round. The following week at the Tier-II LA Championships, Hantuchová retired from her third-round match with Elena Dementieva while trailing, 3–6, 1–4. Hantuchová once again fell out of the top 10, after losing in the second round of the Tier-II Pilot Pen Tennis tournament in New Haven to eventual runner-up Ágnes Szávay. At the US Open, Hantuchová was the ninth-seeded player but lost to Ukraine's Julia Vakulenko in the first round. It was Hantuchová's earliest loss at this tournament since her debut in 2001 and her earliest loss at a Grand Slam tournament since the 2004 French Open.

Hantuchová then played four consecutive tournaments. She reached her second final of the year at the Tier-III Bali Classic, losing to Lindsay Davenport in three sets.

Hantuchová then lost to world No. 6 Ivanovic in the final, after leading the match, 6–3, 3–0. At the Porsche Tennis Grand Prix in Stuttgart, Hantuchová defeated Šafářová in the first round, but lost in the second round to Dementieva. This loss, however, did not prevent Hantuchová from rising to world No. 9, her highest ranking in over four years.

At the Tier-I Zurich Open, Hantuchová defeated Dinara Safina in the first round, before losing to Agnieszka Radwańska. One week later, Hantuchová won her third career title at the Tier-II Generali Ladies Linz. In the semifinals, she defeated Vaidišová for the first time in her career. Hantuchová then defeated Schnyder in a straight-sets final. This title enabled Hantuchová to qualify for the year-end WTA Tour Championships in Madrid. But Hantuchová did not advance past the round-robin stage. She lost to Sharapova and Ivanovic, before beating Kuznetsova to finish third in her group. Hantuchová's win–loss record for 2007 was 52–28.

In the quarterfinals, she beat Polish teenager Agnieszka Radwańska, who had defeated second-seeded Svetlana Kuznetsova and Nadia Petrova in earlier rounds. Hantuchová then lost to Ana Ivanovic in the semifinals, despite Hantuchová having won the first set 6–0, and leading the second set 2–0. After the match, Hantuchová claimed that Ivanovic had been distracting her by squeaking her shoes on the court before serving, a claim Ivanovic disputed.[28] Hantuchová's performance at this tournament caused her ranking to improve one spot to world No. 8.

Hantuchová then played two indoor tournaments in Europe. At the Open Gaz de France in Paris, she lost to seventh-seeded Ágnes Szávay in the quarterfinals. She was the third-seeded player at Antwerp, where she again reached the quarterfinals. A blister on her right hand caused Hantuchová to retire during the quarterfinal against Timea Bacsinszky.

Hantuchová in July 2008

Hantuchová was then scheduled to play at the Qatar Open, the first Tier-I event of the year, and the Dubai Championships, a Tier-II event, but withdrew from both because of fatigue. Hantuchová played both of the two-week Tier I events in the United States. At Indian Wells, Hantuchová was the defending champion and fifth seed.

The following week at the Tier-II event on clay in Amelia Island, Hantuchová was the third seed, but lost in the second round to Karolina Šprem. Hantuchová spent the month of May and most of June recovering from a stress fracture in her right foot, which resulted in her withdrawal from the Tier-I Italian Open in Rome,[29] the Tier III İstanbul Cup,[30] the French Open,[31][32] and the Rosmalen Open in 's-Hertogenbosch.

However, she lost to world No. 39 Sorana Cîrstea in the quarterfinals. Because she won only 11 of 26 singles matches after the Indian Wells tournament, Hantuchová finished the year ranked world No. 21, her lowest year-end ranking and first finish out of the top 20 since 2004. She was 0–5 during the year versus players ranked in the top ten at the time the matches were played, with losses to Ivanovic, Sharapova, Janković, and Zvonareva (twice).
