Two-time defending champion Aryna Sabalenka will attempt to win a third US Open title when she meets Elena Rybakina in Saturday's final. And since Rybakina just took over Sabalenka's world No. 1 ranking, Sabalenka probably feels she has something to prove. Who will win? Our experts break it down.

What can Rybakina do to defeat Sabalenka? D'Arcy Maine: Rely on the big-serving game that has gotten her here and, to quote Coco Gauff, continue to "be there every point" and put "a lot of pressure on [her opponent's] service game and return game." Simon Cambers: Keep doing what she's been doing: winning. Effectiveness on first serve is crucial. In six of her 10 defeats to Sabalenka, she won less than 60% of points on her first serve; in all but one of her seven wins, she won more than 70%. At this year's US Open, she's been winning 80% of points on first serve. Bill Connelly: Get the return in play. When Rybakina beat Sabalenka in the Australian Open final, she was aced only 5.8% of the time, and she won 80% of the midlength rallies (4-6 shots) on Sabalenka's serve. Aishwarya Kumar: What's most impressive about Rybakina is her stoicism. If she goes in with the same approach against Sabalenka, she has a great chance of winning.

What can Sabalenka do to defeat Rybakina? Maine: According to Jessica Pegula, if Sabalenka plays like she did in their semifinal clash, she's virtually unstoppable.
