Mirjana Lučić Baroni

Early life and junior success

Lučić began playing tennis at age four by hiding in the car when her older sister went to tennis classes and then sneaking into the lessons herself. As a junior player, she won the girls' singles title at the US Open in 1996, and the girls' singles and doubles crowns at the Australian Open in 1997, becoming the third player in the Open Era to win two junior Grand Slam singles titles before her 15th birthday (the others being Martina Hingis and Jennifer Capriati).

1997–98: Grand Slam title

Lučić turned professional in April 1997 at the age of 15. One week after turning pro, she won the first WTA Tour event she played in at Bol. She then reached the final of her second career event in Strasbourg, where she lost to Steffi Graf.

In 1998, playing in her first tour doubles event, Lučić became the youngest player in history to win a title at the Australian Open at the age of 15 years, 10 months and 21 days, when she and Hingis won the women's doubles title. The win made Lučić the first player to win both the first singles and doubles events they had ever played in on the WTA Tour. She went on to win the second doubles event of her career when she partnered with Hingis to win the Pan Pacific Open in Tokyo. Later that year, Lučić defended her singles title at Bol, becoming the youngest player ever to defend a tour title at age 16 years, 1 month and 24 days. She also finished runner-up in the 1998 mixed doubles event at Wimbledon, partnering with Mahesh Bhupathi.

1999: Wimbledon semifinal, personal problems

In 1999, Lučić achieved her career-best Grand Slam singles performance when she reached the semifinals at Wimbledon, before losing in three sets to Graf. She beat Erika de Lone and Mariana Díaz Oliva before she beat world no. 4 and nine-time Grand Slam champion Monica Seles in the third round. She saw off Tamarine Tanasugarn and then beat 1998 Wimbledon finalist Nathalie Tauziat in the quarterfinals after Tauziat served for the match twice in the third set.

After 1999, Lučić suffered a series of personal and financial problems and failed to make any further significant impact on the tour. She said that she had been abused by her father, Marinko, from early childhood. She continued to compete until the 2003 US Open, then proceeded to take an extended hiatus from competition; her career-high world rankings were world number 32 in singles and world number 19 in doubles (both achieved in 1998). She played only two tournaments in the 2004, 2005, and 2006 seasons combined.

2007–08: Return to tour

Mirjana Lučić gave an interview in the New York Daily News in April 2006 explaining why she stopped playing and describing her life with an abusive father, vowing that would not stop her and she would continue to fight to the end. She had been training with a new coach, Ivan Beros, and said she was fit and ready to continue tennis.

As a wildcard in the qualifying draw of the Cellular South Cup in Memphis in February, Lučić won one match (defeating Melanie Oudin) before losing in the second round to Natalie Grandin. She was also awarded a wild card to the 2007 Pacific Life Open at Indian Wells in March, where she again won her first match before losing in the second round.

She also received a wild card to the Tiro A Volo tournament in Rome, where she lost in the first round to Karin Knapp. That was her third tournament within the previous 12 months, and she received her first WTA ranking (number 524) since her return to the professional tour.

Even though she lost the first round to Knapp in the $100,000 Rome Challenger, she received a qualifying wildcard for the 1.3 million dollar tournament in May at the same city and beat the 65th-ranked player in the world, Elena Vesnina. She then went on to lose to Catalina Castaño in the second round. Her ranking jumped to 444 with the result.

Lučić played a mixture of ITF and WTA qualifiers in 2008, her best result reaching the quarterfinals in Florence in May. In September 2008 Mirjana started working with her new coach Alberto Gutierrez, planning to play a full schedule the following year.

2009–11

In the 2009 season, she was given a wildcard into the ASB Classic in Auckland, New Zealand. In her first WTA main draw match since 2007 Indian Wells, she lost to Anne Keothavong in the first round.

Lučić then continued to toil on the ITF challenger circuit for several years prior to mounting somewhat of a comeback in the 2010 season. During that year, Lučić won her first title in 12 years at a $25,000 ITF event in Jackson, Florida on 11 April. Shortly after, Lučić qualified for the WTA event in Birmingham, going on to win her first main draw match since 2007 Indian Wells, this time over Colombian Mariana Duque. She continued her good form as she defeated fellow Croatian player Karolina Šprem in the second round. She was beaten by top 20 player Aravane Rezaï of France in the third round. Lučić then competed in the Wimbledon Qualifying tournament in Roehampton. She won her first two rounds and beat Michaëlla Krajicek in the third round to qualify for the main draw of Wimbledon, her first Grand Slam since the 2002 US Open. After a good showing, Lučić fell to 14th seed Victoria Azarenka in the first round on Centre Court.

After Wimbledon, Lučić moved onto the European summer clay court events. She failed to qualify for the 2010 Swedish Open in Bastad but the following week came through three rounds of qualifying at the 2010 Palermo event, and won her first round match, defeating Pauline Parmentier 7–5, 0–6, 7–6 recovering from a 0–4 third set deficit and saving 3 match points. She then fell to third seed Sara Errani in the second round recovering a 2–4 deficit to force a tie-break before falling 0–6, 6–7. Her ranking rose to 151, the highest of her comeback so far.

Following Palermo, Lučić returned to the United States for the summer hard court season. Her first event was the $700,000 Premier event in Stanford, the Bank of the West Classic. Seeded fifth in the qualifying draw, Lučić defeated both Heidi El Tabakh and Tamaryn Hendler in straight sets before repeating her Wimbledon victory over Michaëlla Krajicek with a straight-sets win to qualify for the main draw where she lost to Russian Maria Kirilenko.

In the 2010 US Open, after winning three qualifying matches to enter the main draw, she beat Alicia Molik to set up a second round clash with number four seed Jelena Janković. Lučić lost in three sets. Even with this defeat, this was her best performance in a Grand Slam for nearly a decade.

Lučić started out the 2011 season poorly with a string of early losses on both the WTA and ITF circuits early in the year. Her fortunes began to change during the clay court season where Lučić reached her first WTA Tour quarterfinal in over 10 years at the 2011 Strasbourg event, losing to Anabel Medina Garrigues. She married Daniele Baroni in December 2011.

2012

Lučić-Baroni began the 2012 season losing in qualifying at Brisbane and Sydney in January. She also failed to qualify for the 2012 Australian Open. She struggled to find her form, losing early at the tournaments in Midland and Memphis, as well as the Premier line-up events of Indian Wells, Miami and Charleston. She also lost in the first round at Roland Garros to Svetlana Kuznetsova.

Lučić-Baroni had a breakthrough run at Wimbledon, reaching the third round as a qualifier. She stunned ninth seed Marion Bartoli en route to the second round. However, her run was ended by Roberta Vinci in a tight match.

2014

At the 2014 Wimbledon Championships, Lučić-Baroni faced former number one Victoria Azarenka in the first round but lost to the Belarusian in straight sets, after having set points in the second set.

A few weeks later, a resurgent Lučić-Baroni made major waves at the 2014 US Open. She defeated No. 25 seed Garbiñe Muguruza in the first round, 6–3, 7–6^(7–4), and Shahar Peer in the second round, 6–7^(8–10), 6–3, 6–2, to gain a berth in the third round for the first time since 1998. She then pulled off a huge upset, stunning second seed Simona Halep in straight sets, 7–6^(8–6), 6–2, to win a spot in the Round of 16—the best result of her career at this tournament, and her best showing at a Grand Slam since reaching the semifinals at Wimbledon in 1999. She went on to lose this round to 13th seed Italian Sara Errani in three sets 3–6, 6–2, 0–6.

However, only two weeks later she entered the Quebec City event and reached the singles final, where she pulled off another major upset by beating Venus Williams 6–4, 6–3 on 14 September, setting a record for the longest gap between titles in WTA history, as her previous win happened 16 years and four months earlier at the 1998 Croatian Bol Ladies Open. In addition, paired with Czech player Lucie Hradecká, she won the doubles final of the tournament on the same day.

2015

Lučić-Baroni had a second consecutive finish in the top 100 of the WTA rankings, ending the season ranked No. 67. Her best performance was reaching the semi-finals of the Quebec City event.

2017: Return to a Grand Slam semifinal and career-high ranking

Mirjana entered the 2017 Australian Open ranked 79 in the world. In the first round she beat Wang Qiang in three sets to advance into the second round where she upset the third seed Agnieszka Radwanska in straight sets. In the third round she defeated Maria Sakkari in three sets. In the fourth round she defeated qualifier Jennifer Brady in straight sets to advance to the Quarter-Finals where she pulled another major upset, beating Karolina Pliskova, a heavy favorite to win the tournament in three tight sets where she made her first Australian Open semifinals and her first semifinal appearance since she did so in the 1999 Wimbledon Championships 18 years ago. She then proceeded to lose in two sets against six time Australian Open champion and No. 2 seed Serena Williams. She reached her highest ranking of No.29 on 30th January, eclipsing her previous best of No.32 set in May 1998.
