From 0 to 100: How Swiatek plotted her path

175: Swiatek's ranking on January 1, 2019. The 17-year-old would play her first tour-level main draw a few weeks later at the Australian Open and make her Top 100 debut six months later.

1: In the fall of 2020, Swiatek became the first Polish player -- man or woman -- to win a Grand Slam singles title at the 2020 French Open. 

28: Years since a woman younger than Swiatek won Roland Garros in 2020. At 19 years and 132 days, Swiatek was the youngest Roland Garros champion since Monica Seles in 1992. It had been 23 years since a teenager last won the tournament (Iva Majoli, 1997)

54: Swiatek's ranking going into 2020 Roland Garros, making her the lowest-ranked French Open champion since the computer rankings were introduced in 1975.  

28: Games lost by Swiatek during her 2020 Roland Garros run, tied for the second-fewest games dropped en route to the Paris title. Swiatek sits in second place tied with Chris Evert's 28-game mark in 1979 and behind Stefanie Graf's 20-game mark in 1988.

6: WTA titles won by Swiatek before she became No.1 for the first time, including one Grand Slam and four WTA 1000 titles.

6: Since she claimed the World No.1 spot for the first time, Swiatek is the player with the most Grand Slam titles (3), titles (13), finals (16), wins (131), Top 10 wins (27) and sets won 6-0 (39).

37: Number of consecutive matches Swiatek won in 2022, the longest WTA win streak of the century and longest since Martina Hingis also won 37 in 1997.

8: Number of consecutive weeks Aryna Sabalenka held the No.1 ranking.

11: Consecutive wins by Swiatek to finish the 2023 season, sweeping Beijing and the WTA Finals Cancun, to retake the World No.1 ranking. 

1: Needing to win the match to reclaim No.1, Swiatek conceded just one game against Jessica Pegula in the championships match at the WTA Finals Cancun last fall. It was the fewest games lost in a final at the WTA Finals, breaking the record of two set by Martina Navratilova (1983) and Kim Clijsters (2003).
