CiCi Bellis

Bellis finished the season as only the second American since 1982 to be No. 1 in the year-end girls' junior rankings, earning her the title of 2014 ITF World Champion.

Bellis was also the youngest American to win a match at the US Open since Mary Joe Fernández in 1986.

She was unable to win her next match, losing in three sets to 20 year old Zarina Diyas in the second round.

A month after the US Open, Bellis won her first two professional titles in singles in back-to-back weeks, both in South Carolina at the $25k level.

She also won the USTA National Junior Championship that year at 15 to become the youngest winner of the event since Lindsay Davenport in 1991.

CiCi was born in San Francisco to Gordon and Lori Bellis, and grew up in Hillsborough and Atherton in northern California.

CiCi started playing tennis at age three, but only chose to focus on it over soccer when she was ten years old.

When she was young, she was coached by former top-100 player Monique Javer.

As a child, Bellis aspired to go to college at Stanford, but ended up declining a scholarship to turn pro due to her success as a teenager.

Her tennis idol is Kim Clijsters.

At the age of 15 years and four months, she became the youngest winner of the event since Lindsay Davenport in 1991.

With the victory, she also earned a wildcard into the main draw of the US Open.

Bellis and Black were then both selected to represent the United States at the Junior Fed Cup along with Sofia Kenin.

The trio won the title and Bellis went undefeated in seven matches.

Later in the year, she also reached the semifinals at the Orange Bowl.

With the victory, she became the youngest player to win a match at the US Open since Anna Kournikova reached the fourth round of the 1996 US Open at age 15.

Catherine Cartan "CiCi" Bellis (born April 8, 1999) is an American former tennis player.

Nonetheless, she earned a wildcard into the tournament as the USTA junior national champion, making her the youngest woman in the main draw of a Grand Slam championship since Alizé Cornet at the 2005 French Open, and the youngest in the main draw of the US Open since 2004.

Bellis began playing on the ITF Junior Circuit in late 2012 and mostly participated in low-level Grade-4 tournaments through the end of 2013.

In her WTA Tour-level debut, she upset 12th seed Dominika Cibulková, who was the runner-up at the Australian Open earlier in the year.

Her biggest triumph in the 2013 season was winning Les Petits As in France, a prestigious tournament for juniors between 12 and 14 years old.

She is known for winning a match at the 2014 US Open as a 15 year old against a top-20 opponent, making her the youngest match-winner at the US Open since 1996.

Bellis had an accomplished junior season the same year she played in her first US Open, finishing the 2014 season as the ITF Junior World Champion for holding the year-end world No. 1 junior ranking.

As a junior in the United States, Bellis won six USTA National Junior Singles Championships and was ranked No. 1 in the G18s in April 2014.

In 2014, Bellis played only Grade-B1, Grade-1, and Grade-A tournaments, the three highest levels on the junior circuit.

She had an impressive start to the year by reaching the final at her first five events, winning four of them.

Specifically, she won the Copa del Café in Costa Rica, the USTA International Spring Championships and the Easter Bowl in the United States, and the Trofeo Bonfiglio in Italy.

She followed up this success by also reaching the French Open doubles final with Markéta Vondroušová, which they lost in a match tiebreak.

In contrast, Bellis struggled at the three Grand Slam singles events she entered that year, with her best result being a third round appearance at the French Open.

Nonetheless, she took over the No. 1 ITF junior rank in early September on the strength of those four titles in the first half of the season.

In August 2014, Bellis won the USTA Girls' 18s National Championship, defeating Tornado Alicia Black in the final.

Bellis played her first few low-level professional events in early 2014, and won a doubles title at the $10k event in Orlando in March.

She entered the 2014 US Open ranked No. 1208 with just two professional match wins in singles, both against players ranked outside the top 300.

Bellis closed out her junior career by reaching the semifinals at the 2015 French Open, her best singles result at a Grand Slam tournament and the only junior event she played that year.

In 2015, Bellis was handed a wildcard into the main draw of the Miami Open, her first Premier Mandatory tournament.

She avenged her US Open loss to Zarina Diyas in the second round, before losing to No. 1 eventual champion, Serena Williams.

Her biggest title came at the 2016 Hawaii Tennis Open, a WTA 125 event.

She also won seven singles titles and two doubles titles on the ITF Circuit.

Bellis has a career-high of 35, which she achieved in August 2017.

In early 2018, she was the second youngest player in the top 100 of the WTA rankings.
