Defending US Open champion Jannik Sinner faces a two-front battle in New York — fitness concerns and the relentless Carlos Alcaraz. With their rivalry heating up, Sinner's title defence could hinge on his recovery as much as his tennis.

Alcaraz praises Sinner's level but also warns the Italian that he will 'have a big target on his back' at the US Open.

Sabalenka is currently +285 to repeat as champion, second only to Iga Swiatek at +240. Sinner, meanwhile is favored to repeat at +110, slightly ahead of rival Carlos Alcaraz at +175. With some of those odds in mind, let's take a look at some of the best betting options to consider in both the men's and women's tournaments this year in New York.
