PARIS, June 2 (Reuters) - Marta ⁠Kostyuk came through an emotional all-Ukrainian match to reach a ⁠Grand Slam semi-final for the first time as she beat ‌Elina Svitolina 6-3 2-6 6-2 at the French Open on Tuesday.

The 23-year-old Kostyuk dedicated her victory to the Ukrainian people as tears rolled down her cheeks during ​the on-court interview.

"I want to start with this ⁠historical match I played ⁠with Elina. We had a difficult night in Kyiv, so many people ⁠dead. ‌So I give this match to the Ukrainian people and their resilience. Slava Ukraini," the 15th seed said.

"I want ⁠to point out Elina and her impact on Ukrainian ​tennis, on me ‌and on everyone watching. She's an unbelievable fighter. I'm so ⁠happy to be ​through, but I want to thank her for this incredible match."

Kostyuk surged into a 4-1 lead under the closed roof of Court Philippe Chatrier ⁠before Svitolina clawed a break back in ​front of a sparse crowd.

But Kostyuk broke again to move 5-3 ahead and sealed the opening set when seventh seed Svitolina sent a forehand ⁠long.

The momentum shifted in the second set as Kostyuk's serve deserted her, allowing Svitolina, who has now lost in the quarter-finals at Roland Garros for the sixth time, to level the contest.

The decider turned ​into a tense scrap, with the first ⁠five games going against serve.

Pointing her index finger to her head after ​finally holding for a 4-2 lead, Kostyuk ‌steadied herself before another break and ​a comfortable hold secured victory and a last-four clash with Russia's Mirra Andreeva.
