Jannik Sinner has received a brutal reality check as he prepares to defend his title at the US Open. The world No. 1 recently lifted his fourth Grand Slam trophy at Wimbledon, beating Carlos Alcaraz in the final. If he can retain his crown in Flushing Meadows, he’ll tie Alcaraz on five Majors.

Both women’s and men’s tennis feature two names at the top of the sport that are a cut above the rest in the betting odds. As the U.S. Open starts on Monday, Jannik Sinner is favored ahead of Carlos Alcaraz and Iga Świątek is favored ahead of Aryna Sabalenka.

OK, sure, maybe it wouldn't be rational to say there's no point in actually holding the full U.S. Open and instead just fast-forwarding to the inevitable matchup for the men's championship between Jannik Sinner — assuming he's healthy — and Carlos Alcaraz on Sept.
