PETERSBURG, Fla. -- The WTA announced Tuesday that Iga Swiatek and Katerina Siniakova secured the 2022 WTA year-end No.1 singles and doubles rankings.

This is the first time in her career Swiatek finished the season in the top spot, becoming the 15th player overall. The week of Nov. 7 marks her 32nd week as the WTA World No.1, a position she reached on April 4, 2022. Only Serena Williams (57 weeks), Martina Hingis (80 weeks) and Stefanie Graf (186 weeks) held the top ranking for longer streaks after making their No.1 debut.

By the numbers: The 2022 year-end rankings

Siniakova has secured her third year-end No.1 finish in doubles, which she first achieved in 2018 (when co-ranked with regular partner Barbora Krejcikova) and also again last year in 2021. Siniakova is the first player to outright finish the year as the doubles No.1 in consecutive years since Sania Mirza in 2015 and 2016.

Siniakova, along with Krejcikova, first achieved the No.1 ranking on Oct. 22, 2018 and this week marks Siniakova’s 70th week overall in the top spot.
