NEW YORK -- Aryna Sabalenka came to the US Open struggling and in danger of losing the No. 1 ranking.
She heads to the third round looking every bit ready for a three-peat.
The top-seeded Sabalenka overwhelmed Polina Iatcenko 6-1, 6-1 in 53 minutes on Wednesday night, putting on a power-hitting display that made it seem her recent problems are in the past.
"Happy with the level I played today, happy with the focus and happy to be through this match," Sabalenka said.
Sabalenka is trying to become the first player to win three in a row in Flushing Meadows since Serena Williams from 2012-14, but arrived after losing in the fourth round of her past three tournaments. She needs help to stay atop the WTA rankings even if she wins the title.
She won 15 of 16 points on first serve in the first set and only dropped off a little in the second, finishing 21 for 28 in the match, against an opponent who is playing in her first Grand Slam tournament.
"I think I struggled a little bit in the middle of the season. Once again, I'm not going to defend myself or explain why, what happened, but I'm happy with my level," Sabalenka said. "I can definitely say that mentally I'm way stronger than I was in the middle of the season, and physically I also feel stronger. So I feel like I'm on my level of play."
Sabalenka has dropped only eight games through her first two matches, her fourth-fewest en route to the third round of a major in her career. She improved to 16-0 against qualifiers and hasn't dropped a set in any of those matches.
Sabalenka next faces Kamilla Rakhimova, against whom she is 3-0, including a 6-1, 6-0 win at the French Open in 2025.
