Sabalenka dispatched Camila Osorio 6-4, 6-4 in her US Open title defense on Monday, advancing smoothly in her quest to become the first player since Serena Williams to win three consecutive US Open titles. Williams accomplished the feat from 2012 to 2014. Sabalenka enters the tournament as the defending champion after winning last year, and this opening round victory shows she's not taking her foot off the gas early. Osorio offered little resistance as the second seed controlled the match from start to finish, breaking serve at crucial moments and dictating rallies with her aggressive baseline game. The Argentine has been dealing with an uneven stretch leading into New York, but this dominant performance suggests she's found her rhythm heading into the meat of the draw. If Sabalenka continues playing at this level, she'll be difficult to beat. The path to three straight US Open crowns is lengthy, but she's off to exactly the kind of start she needed.
