No. 1 seed Jannik Sinner is facing off against No. 12 Taylor Fritz, as Fritz is looking to become the first American man to win a Grand Slam since Andy Roddick won the U.S. Open in 2003.

It's been a busy week for Kelce and Swift, as the 14-time Grammy Award-winner was seen at the Chiefs' Week 1 win over the Baltimore Ravens on Thursday.

Kansas City won by the final score of 27-20, with Kelce hauling in three receptions for 34 yards. Mahomes completed 71.4 percent of his passes for 291 yards and a touchdown to go along with an interception.

As for Fritz, he earned his spot in the final after taking down fellow American Frances Tiafoe in a hard-fought match that lasted five sets.
