'''Sesil Radoslavova Karatantcheva''' ({{langx|bg|Сесил Радославова Каратанчева}}; born 8 August 1989) is a Bulgarian former [[tennis]] player.
On 7 November 2005, she reached her best singles ranking of world No. 35. On 19 April 2010, she peaked at No. 154 in the doubles rankings.
In her career, she won nine singles titles on the [[ITF Women's Circuit]]. 

Karatantcheva is perhaps best known for reaching the quarterfinals of the [[2005 French Open]], upsetting seven-time Grand Slam champion [[Venus Williams]] en route.

==Tennis career==
She began playing tennis at the age of five.<ref name="dnes651111109.bg">{{cite news|author=Nesterova, Maria| work=dnes.bg|title=Звезден рожденик: Сесил Каратанчева на 27.

===2003–2004: Early career===
Karatantcheva played her first professional tournament in September 2003 in Sofia, Bulgaria at the age of 14. As an unranked qualifier the next week, she defeated the No. 1, 2, and 3 seeds en route to her first professional tournament title at a small [[ITF Women's Circuit|ITF]] tournament in Volos, Greece. Karatantcheva went on to win two other ITF titles in 2003.
In 2004, Karatantcheva began her season at the [[WTA Tour|WTA]] tournament in Indian Wells, where she defeated [[Alexandra Stevenson]] in the first, and upset the 17th seed [[Magüi Serna]] in the second round. In an interview prior to her match against 16th seed [[Maria Sharapova]], Karatantcheva claimed that Sharapova had skipped a hitting session with her a few weeks earlier in Florida, and began a war of words with the Russian.<ref>{{cite web |url=http://www.dnevnik.bg/sport/2016/03/09/2719828_sesil_karatancheva_sharapova_mami_ot_10_godini_no_shte/|title=Сесил Каратанчева: Шарапова мами от 10 години, но ще й се размине|publisher=dnevnik.bg |date=9 March 2016|access-date=7 May 2016 | language = bg}}</ref>

Sharapova then defeated Karatantcheva in three sets in the third round. On April 19, she played her first match for the [[Bulgaria Fed Cup team]]. Because of her age, Karatantcheva was restricted in the number of tournaments she was able to play. In August, she reached the quarterfinals of a WTA tournament in Vancouver, British Columbia, and qualified for the [[US Open (tennis)|US Open]], before losing to eventual champion [[Svetlana Kuznetsova]] in the first round. Karatantcheva also reached the quarterfinals of the WTA tournament in Québec City, and captured another ITF tournament in December at Palm Beach Gardens. In 2004 she became the French Open junior champion.{{citation needed|date=July 2022}}

===2005: Breakthrough and first French Open quarterfinal===
2005 was Karatantcheva's breakthrough year. She started off the year at the tournament in Gold Coast, Australia by qualifying, and then defeating the tournament's No. 7 seed [[Elena Likhovtseva]] before falling in the quarterfinals. She then qualified for the [[Australian Open]], losing to the No. 4 seed Sharapova in the first round. Her most successful tournament to date was at [[French Open|Roland Garros]] where Karatantcheva defeated the No. 19 seed [[Shinobu Asagoe]] in the second round, and then stunned the world with her victory over the No. 11 seed and former world number one [[Venus Williams]] in the third round.  After defeating [[Emmanuelle Gagliardi]], she fell to Likhovtseva in the quarterfinals. Karatantcheva became the youngest female to reach the quarterfinals of a Grand Slam tournament since [[Martina Hingis]] in 1996. At [[2005 Wimbledon Championships|Wimbledon]], she lost to Sharapova once again, being able to win just one game.{{citation needed|date=July 2022}}

In 2005, Karatantcheva also won a European club championship in Rennes as a member of the Cherno More Elite team (Bulgarian: Черно море Елит). Her teammates were Virginiya Trifonova, [[Maria Penkova]] and [[Tsvetana Pironkova]].<ref name="personi.bg"/>

At the end of the year, Karatantcheva came up eighth in the [[Bulgarian Sportsperson of the Year]] rankings, earning 676 points.<ref name=temanews22.bg>{{cite web |  title =За пръв път шахматист на върха - Веселин Топалов стана спортист номер едно на 2005-а със смазваща преднина | work =temanews.com | author=Kamenov, Kostadin| date =December 2005 | url =http://www.temanews.com/index.php?p=tema&iid=131&aid=3502| access-date =23 December 2014 }}</ref><ref name=monitor22.bg>{{cite web | title =Президентът аплодира жест на Спортист №1 за 2005 г., Топалов помогна на болните деца с джип за 64 000 лева | work =monitor.bg | author =Stoyanov, Asen | date =23 December 2005 | url =http://www.monitor.bg/article?id=64693 | access-date =2014-12-24 | url-status =dead | archive-url =https://web.archive.org/web/20141224181816/http://www.monitor.bg/article?id=64693 | archive-date =24 December 2014 }}</ref> She was also honoured by the Bulgarian Tennis Federation as the "Best female tennis player of the year".<ref name=bgtennis22.bg>{{cite web | title =Годишни награди на Българска Федерация по Тенис - 2005 | work =bgtennis.bg | date =2005 | url =http://bgtennis.bg/pub/docs/nagradi.pdf | access-date =2015-03-15 | archive-url =https://web.archive.org/web/20150402095937/http://bgtennis.bg/pub/docs/nagradi.pdf | archive-date =2015-04-02 | url-status =dead }}</ref>

On December 20, 2005, the French sports newspaper ''[[L'Équipe]]'' reported that Karatantcheva had failed a drug test earlier in the year at Roland Garros (after the 1/4 final match against Likhovtseva),<ref name=standartnews8864756845757u7424212.bg>{{cite web |  title =Французи клеветят Сесил Каратанчева. Журналист от "Екип" забърка в допинг скандал 16-годишното дете чудо в тениса| work =standartnews.com| date =21 December 2005 | url =http://paper.standartnews.com/bg/article.php?d=&article=27383| access-date =31 August 2017 }}</ref> and that she had appeared in front of a three-person panel of judges to explain the results. The newspaper claims that Karatantcheva said she was pregnant at the time of the test, which would explain the high levels of [[nandrolone]] in her system. Karatantcheva has denied all allegations, saying "I am shocked. I have not appeared before judges of the international federation."{{citation needed|date=July 2022}}

===2006–2007: Doping scandal and two-year suspension===
On 11 January 2006, the ITF issued a two-year ban after two positive drug tests for nandrolone. While Karatantcheva has claimed she was pregnant at the time of one of the tests, another laboratory carried out a pregnancy test on her urine sample, and it tested negative. On 3 July 2006, the [[Court of Arbitration for Sport]] denied her appeal to overturn the ban with the argument that said nandrolone was found in concentrations which were inconsistent with the normal levels for that stage of pregnancy.<ref>{{cite news | title=Karatantcheva ban appeal rejected | date=2006-07-03 | publisher=BBC Sports | url =http://news.bbc.co.uk/sport1/hi/tennis/5141998.stm | access-date = 2008-02-03 }}</ref>

Karatantcheva did not play any matches in 2006 or 2007 following her drug ban. She mainly trained in [[Pravets]].

===2008===
[[File:Sesil us open.JPG|thumb|Karatantcheva at the 2008 US Open]]
Karatantcheva's first match after the ban was in a pre-qualification tournament for a wildcard into the $25k tournament in Surprise, Arizona. She won three matches in one day to win the event and thus won a wildcard for the qualifying draw, in which she beat Susanna Lingman, Maria Kondratieva, and [[Kristína Kučová]]. In the main draw, Karatantcheva beat the fifth seed [[Sunitha Rao]] in three sets in the first round, and [[Robin Stephenson]] in the second round. In the quarterfinals, Karatantcheva beat [[Magdaléna Rybáriková]] in two sets, and in the semifinals she defeated the second seed [[Viktoriya Kutuzova]]. In the finals, Sesil played a tough three-set match and overcame the eighth seed American [[Angela Haynes]].<ref name=topsport77.bg>{{cite web | title =Сесил Каратанчева с титла в Аризона, софиянката надигра Анджела Хейнс с 6:2, 4:6, 6:4 | work =topsport.bg| author=Pashkurov, Nikolay| date =22 January 2008 | url =http://topsport.ibox.bg/news/id_1376665814| access-date =24 December 2014}}</ref>

In late January, still unranked, she entered another $25k tournament at La Quinta, and again battled through three rounds of qualifying into the main draw, despite a scare in her qualifying match against American player [[Stacia Fonseca]], who took the first set. Having fended off a spirited challenge from second-seeded [[Angelika Bachmann]] in the first round of the main draw, she made light work of subsequent opponents en route to the semifinals, where for the second tournament in succession she was scheduled to play Viktoriya Kutuzova. This time, the match ran to three sets, but Karatantcheva ultimately prevailed in three sets. In the final, Karatantcheva defeated the third seed [[Sandra Klösel]].

Karatantcheva attracted criticism from the Bulgarian tennis federation for competing at La Quinta in preference to participating in Bulgaria's [[Fed Cup|Federation Cup]] tie scheduled the same week.<ref>{{cite news | title=Karatantcheva in hot water for skipping Fed Cup event | date=2008-01-28 | publisher=Guardian Sport | url =http://sport.guardian.co.uk/breakingnews/feedstory/0,,-7261391,00.html | access-date = 2008-02-03 }}</ref> She was accused of breach of contract and threatened with a fine, but the Bulgarian teenager stood by her decision, which she had taken on the grounds that it was proving extremely difficult for her to gain entry even to low-level tournaments following the loss of all her ranking points and any right to protected ranking status after her ban, so she needed to work at re-establishing herself at least in the mid-hundreds of the [[WTA rankings]] as a matter of priority before tending to national team commitments.

In February, the Bulgarian was awarded a wildcard into the $75k Midland Classic, but her winning streak came to an abrupt end as she was defeated in the first round by qualifier [[Valérie Tétreault]] of Canada, who had raced through the three qualifying rounds for the loss of just nine games, five of them against former top 50 star [[Mirjana Lučić]]. Karatantcheva then attempted to qualify for the WTA Tier III event in Memphis but lost in the first round of qualifying to [[Hana Šromová]] of the Czech Republic.

In early March, she qualified for the $50k Las Vegas event including victories over [[Amber Liu (tennis)|Amber Liu]] and [[Elena Bovina]]. However, she lost in the first round of the main draw to wildcarded American [[Madison Brengle]]. She also received a wildcard into the qualifying event for the Tier I event at Indian Wells but lost in the first round of qualifying to [[Evgeniya Rodina]]. Her luck changed however, when, at the end of March, she managed to qualify and reach the final of the $50k event in Latina, losing to [[Iveta Benešová]] in straight sets.

In April, she reached the quarterfinals of the $25k event at Civitavecchia, losing to [[Betina Jozami]] of Argentina in straight sets. Her route through to the final of the $25k event in Palm Beach Gardens, Florida, included a victory over seventh-seeded [[Lauren Albanese]]. Argentinian [[Soledad Esperón]] beat her in two sets in the final.

In May, she played her first WTA main-draw match since her suspension in Fes, Morocco against [[Elena Baltacha]] which she won in straight sets.
In June, Sesil reached the quarterfinals of the $75k tournament in Marseille. In the qualifications of Wimbledon, she lost in the second round to [[Magdaléna Rybáriková]] from Slovakia.

===2009: Representing Kazakhstan===
On 10 January 2009, it was announced that Karatantcheva would take Kazakh citizenship and compete for the [[Kazakhstan Fed Cup team]].<ref name=Kazakhstan>{{cite web |  title =Briefs 2-Bulgarian Karatantcheva to play tennis for Kazakhstan  | work=Reuters | date =10 January 2009 | url =http://uk.reuters.com/article/tennisNews/idUKLA54924020090110 | archive-url =https://archive.today/20120722135720/http://uk.reuters.com/article/tennisNews/idUKLA54924020090110 | url-status =dead | archive-date =July 22, 2012 | access-date =16 January 2009 }}</ref><ref name=Bulgaria>{{cite web |  title =Дора Рангелова: и Данчо Йовчев го искаха, но той остана.

In tournament play in January, she reached the second round (as a qualifier) at the Brisbane International, defeating top 50 player Iveta Benešová along the way and then backed it up by playing (and winning) her first main-draw major match (again as a qualifier) at the Australian Open. She then lost in the second round to [[Peng Shuai]]. This was to be her last main tournament playing for Bulgaria until 2015.<ref name=Bulgaria979>{{cite web | title =Сесил влезе в основната схема на "Аустрелиън Оупън", българката победи Варвара Лепченко за 53 минути| work =topsport.bg | date =18 January 2009| url =http://topsport.ibox.bg/news/id_316053214| access-date =4 January 2015 }}</ref>

At the [[2010 PTT Pattaya Open – Singles|Pattaya Open]], Karatantcheva reached her first WTA semifinal, before losing to [[Tamarine Tanasugarn]]. Karatantcheva qualified for the [[Aegon Classic|Birmingham Classic]] where she reached the quarterfinals winning five matches in a row, upsetting [[Yaroslava Shvedova]] in straight sets in the second round, before losing to second seed Maria Sharapova.

===2011===
Karatantcheva failed to qualify in [[2011 Brisbane International|Brisbane]], [[2011 Australian Open|Melbourne]], [[2011 PTT Pattaya Open|Pattaya]], and [[2011 Monterrey Open|Monterrey]]. She reached the final of a $25k event in Clearwater, Florida, losing to [[Ajla Tomljanović]]. At the [[2011 French Open|French Open]], she lost to [[Olga Govortsova]] in the final round of qualifying. After barely missing out on qualifying for the [[2011 Aegon Classic|Birmingham Classic]], Karatantcheva fell to [[Arina Rodionova]] in the first round of qualifying of [[2011 Wimbledon Championships|Wimbledon]]. She took a two-week break following Wimbledon.

She returned at the [[2011 Internazionali Femminili di Palermo|Palermo Ladies Open]], where she qualified for the main draw. She drew second seed [[Roberta Vinci]] in the first round. Although Karatantcheva played well she was beaten in straight sets. She then competed in two $100k events – in [[Bucharest]] and [[Astana]], losing in the early round of both tournaments.

She then failed to qualify for the [[2011 US Open (tennis)|US Open]], marking the first year since 2009 that she had not competed in the main draw of a major. Her poor form continued, losing in the first or second rounds of four more ITF tournaments.

She began to improve her game by advancing to the semifinals of a $50k event in Troy, Alabama. She then competed in a $25k tournament in [[Rock Hill, South Carolina|Rock Hill]], losing in the quarterfinals. Karatantcheva then played  at the $50k event in [[Grapevine, Texas]], where she advanced to the final, losing to eighth seed [[Kurumi Nara]] in three sets. Following her performance in Grapevine, Sesil achieved her best result of the year by winning a $75k tournament, the [[2011 Goldwater Women's Tennis Classic|Goldwater Women's Tennis Classic]], in Phoenix, Arizona, the biggest title of her career. She won the title dropping only two sets the entire tournament, defeating a seeded player along the way. Karatantcheva's recent change in form has propelled her well back inside the top 200 and she established herself as one of the leading Kazakh players.

===2012===
Karatantcheva began the year ranked World No. 139. She failed to qualify in Brisbane and at the Australian Open. She then competed in the $100k tournament in [[2012 Copa Bionaire|Cali]]. Unseeded, she advanced to the semifinals before losing to [[Mandy Minella]]. She then played at the [[2012 Copa Sony Ericsson Colsanitas|Copa Sony Ericsson Colsanitas]] and [[2012 Monterrey Open|Monterrey Open]]. Although she qualified for both, she lost in the first round to [[Catalina Castaño]] and Yaroslava Shvedova, respectively. Sesil then qualified for the [[2012 Abierto Mexicano Telcel|Abierto Mexicano Telcel]]. Although she put up a fight, Sesil was defeated by sixth seed [[Johanna Larsson]] in three sets, in the first round. Karatantcheva committed 18 double faults during the match – almost an all-time high in WTA history. Karatantcheva then competed at the [[2012 BNP Paribas Open|Indian Wells Open]] and the [[2012 Sony Ericsson Open|Miami Open]], losing in the first round of qualifying for both tournaments. Despite the losses, she rebounded and reached the final of a $50k event, losing to [[Arantxa Rus]].

Karatantcheva headed to Portugal for the [[Portugal Open|Estoril Open]]. In the first round of qualifications, she drew Italian [[Maria Elena Camerin]], whom she defeated in three tough sets. In the second round of qualifying, however, she was defeated by [[Mariana Duque-Marino]], despite the fact she was leading with a break in the deciding set. Karatantcheva then lost in the first round of qualifying of the [[2012 Mutua Madrid Open|Madrid Open]]. At the French Open, she lost in the final round of qualifying to [[Alexa Glatch]]. However, she was offered a spot in the main draw after the withdrawal of [[Vera Zvonareva]]. She played [[Tímea Babos]] in the first round and won in two easy sets. This was Karatantcheva's first Grand Slam tournament main-draw appearance in almost {{frac|2|1|2}} years.

She opened her grass-court season at [[2012 Aegon Classic|Birmingham]] where she entered the qualifying draw and defeated local girl Francesca Stephenson but fell to Thailand's [[Noppawan Lertcheewakarn]] in the final round. However, she was offered a place in the main draw as a lucky loser due to the withdrawal of another player. She faced another Thai player, Tamarine Tanasugarn, defeating her in straight sets. Her run was ended in the second round by eighth seed Ekaterina Makarova. She then lost in the final round of qualifying at [[2012 Wimbledon Championships|Wimbledon]].

She then continued her hardcourt season at the [[2012 Rogers Cup|Rogers Cup]] in Montreal. As the 18th seed in qualifying, she won three matches for a place in the main draw. In the first round she dismantled [[Sorana Cîrstea]], without losing a single game, in only 43 minutes. Karatantcheva lost to 16th seed [[Lucie Šafářová]] in the second round in straight sets.

Her next tournament was the [[2012 US Open (tennis)|US Open]]. Ranked world No. 85, she was given direct entrance into the main draw. She lost to [[Lourdes Domínguez Lino]] in the first round.

Following the US Open, Karatantcheva competed in [[2012 Bell Challenge|Québec]] and [[2012 Hansol Korea Open|Seoul]], losing in the first round of both tournaments. She continued by then losing in the qualifying draw of the next four events in [[2012 Toray Pan Pacific Open|Tokyo]], [[2012 China Open (tennis)|Beijing]], [[2012 Generali Ladies Linz|Linz]], and [[2012 Kremlin Cup|Moscow]]. Her final tournament of the year was in [[2012 Goldwater Women's Tennis Classic|Phoenix]], where she was the defending champion and second seed.

Despite the loss, she ended the year at No. 93, her first year-end ranking inside the top 100 since 2005.

===2013===
Karatantcheva began the season at the [[2013 Australian Open|Australian Open]], losing to 6th seed [[Li Na]] in the first round. She next played for Kazakhstan in [[2013 Fed Cup|Fed Cup]]. Placed in the Asia/Oceania Zone Group I in [[Astana]], Karatantcheva played with [[Galina Voskoboeva]] to beat [[Rutuja Bhosale]] and [[Ankita Raina]], securing Kazakhstan's 3–0 sweep over [[India Fed Cup team|India]]. Following Kazakhstan's win over [[Thailand Fed Cup team|Thailand]], they defeated [[Uzbekistan Fed Cup team|Uzbekistan]] in the Group I promotional play-off.

At the [[2013 Sony Open Tennis|Miami Open]], she entered the qualifying draw and defeated [[Anastasia Rodionova]] in the first round, saving two match points and battling almost three hours before winning. She lost in the final round to [[Sílvia Soler Espinosa]]. Karatantcheva closed the hard court season with a first round loss in [[2013 The Oaks Club Challenger|Osprey]] to [[Olga Puchkova]].

Karatantcheva opened her clay court season by falling in the qualifying rounds in [[2013 Family Circle Cup|Charleston]] and [[2013 Portugal Open|Oeiras]]. She then won only two matches in her next four tournaments before heading to [[2013 Wimbledon Championships|Wimbledon]], where she lost in the final round of qualifying to Austrian [[Yvonne Meusburger]] in a close three-set match. Following Wimbledon, Karatantcheva played two more clay-court events in [[2013 Budapest Grand Prix|Budapest]] and [[2013 Swedish Open|Båstad]], losing to [[Simona Halep]] and Serena Williams, respectively.

After skipping the first week of the [[US Open Series]], Karatantcheva entered the [[2013 Southern California Open|Southern California Open]] in Carlsbad. She played the qualifying draw and won three consecutive matches against Chieh-yu Hsu, [[Katalin Marosi]], and [[Ivana Lisjak]] for a spot in the main draw. There, she drew Julia Görges and defeated the world No. 42 in straight sets. She advanced to the second round but lost to eventual champion [[Samantha Stosur]], winning only five games. Despite the loss, her win over Görges was the biggest win of her season. Her next tournament was the [[2013 Rogers Cup|Rogers Cup]] in Toronto where she fell in the first round of qualifying. Her ranking plummeted to No. 163 as a result of her failure to defend 2012's second round points.
