LONDON -- Dominika Cibulkova on Tuesday said she has retired from tennis.
The 30-year-old Slovak reached the 2014 Australian Open final and won the WTA Finals in 2016.
WTA president Micky Lawler praised Cibulkova's "extraordinary finesse, speed and feel of the court."
The 5-foot-3 Cibulkova never won another tour-level title after the 2016 WTA Finals and played her last match at the French Open in May, losing to Aryna Sabalenka.
Her career-best ranking was No. 4, which she achieved in May 2017.
Cibulkova has a tennis academy and a charity focused on helping Slovakian athletes adapt to life after elite-level sport.
