Katerina Siniakova outlasts Elena Rybakina in marathon to take Portoroz title

Kazakhstan's Rybakina, ranked 25th in the world and the last remaining seed in this hard court tournament, raced to a 5-0 lead in the first set but needed a tiebreak after Czech Siniakova fought back. Rybakina was a break up at 4-3 in the second set, but Siniakova again fought back and this time took the tiebreak with her third set point.

Siniakova, who had played both her quarter-final and semi-final on Saturday, broke first in the third set, but Rybakina broke back to 4-4. Siniakova immediately broke again and served out for the victory.

It was a first singles title since Bastad in 2017 for the 26-year-old who has become a doubles specialist. With Barbora Krejcikova, Siniakova has won the Australian Open, Wimbledon and the US Open this year.
