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.

Jannik Sinner is currently the world No. 1 and has won two of the three Grand Slam titles this year, but fans still think Carlos Alcaraz will end up with more major titles

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.
