Marta Kostyuk defeated Katherine Sebov on Tuesday to advance to the third round of the National Bank Open in Toronto [1].
The victory keeps Kostyuk in contention at the WTA event while eliminating the Canadian home-crowd favorite from the singles draw [1].
The match took place on Aug. 4 [2]. Kostyuk secured the win with a final score of 7-6 (4), 6-0 [1].
The first set proved to be the primary battle of the match, ending in a tiebreak that Kostyuk won 7-4 [1]. Following the narrow victory in the opening set, Kostyuk dominated the second set to close out the match without dropping a single game [1].
Sebov, playing in her home country, was unable to maintain the momentum needed to challenge Kostyuk after the first-set tiebreak. The stark contrast between the two sets highlighted a shift in momentum that favored the advancing player.
Kostyuk now moves forward in the tournament bracket to face her next opponent in the third round. The National Bank Open continues to serve as a critical stop for players looking to build momentum in the summer hard-court season.

This result demonstrates Kostyuk's ability to maintain mental composure during high-pressure tiebreaks and her capacity to accelerate her game once a momentum shift occurs. For Sebov, the loss underscores the difficulty of sustaining a high level of play against top-tier opponents throughout a full match, particularly when facing a deficit after a close first set.
