Anett Kontaveit has overcome Maria Sakkari in three tight sets to claim the St. Petersburg Ladies Trophy, her fourth straight WTA Tour indoor title.
The second-seeded Kontaveit came back from a set down to defeat her Greek opponent 5-7 7-6 (7-4) 7-5 — improving her head-to-head against Sakkari to 7-6.
Kontaveit needed nearly three hours to beat the top-seeded Sakkari, recovering from being a break down in the second and third sets to claim her sixth singles title overall.
The Estonian joins elite company in becoming just the sixth player to record 20 consecutive indoor win since 1989, which includes her runs to titles at Ostrava, Moscow and Cluj-Napoca at the end of last season.
The other five players to have achieved that unbeaten feat are all major champions and former world No.1s — Steffi Graf (43 wins), Monica Seles (32), Lindsay Davenport(22), Justine Henin (22) and Jana Novotna (21).
Kontaveit will move up three spots to a career-high sixth in the rankings when they are updated while Sakkari will drop one spot to world No.8.
