Marta Kostyuk reached her first career WTA final by taking five of the last six games and beating Danielle Collins 6-4, 6-3 at the ATX Open on Saturday.

Kostyuk, the No. 8 seed, saved five of the six break points she faced and won four of 2022 Australian Open runner-up Collins' service games.

The 20-year-old from Ukraine who had previously reached the semifinals at four tournaments but never made it past that round.

"Obviously a special moment, very emotional," Kostyuk told press afterward. "I lost four semifinals prior to this match today, and I didn’t know what to expect. Danielle is a great player, a great champion. Very happy that the match turned out this way today."

She will face one of two unseeded players for the championship of the inaugural edition of the hard-court tournament in Austin: Katie Volynets of the United States or Varvara Gracheva of Russia. They were scheduled to meet in the second semifinal on Saturday night.

The fourth-seeded Collins was trying to reach her first tour title match since getting that far at Melbourne Park last season before losing to Ash Barty. Collins fell to 0-5 against seeded opponents and her career mark in WTA semifinals is now 3-9.
