The last few matches of the US Open men's singles draw are setting up nicely for tennis fans.

World No. 1 Carlos Alcaraz steamrolled No. 12 seed Alexander Zverev 6-3, 6-2, 6-4 on Wednesday night to set up a semifinal clash with No. 3 seed Daniil Medvedev. On the other side of the bracket, 22-time Grand Slam champion Novak Djokovic will face unseeded American Ben Shelton after the latter's upset of Frances Tiafoe in the quarterfinals.

So the final Grand Slam of the season will come down to the three best players in tennis, who have all won the event in the last five years, and a 20-year-old underdog who turned pro 13 months ago.

BetMGM has Djokovic as the favorite to win the tournament at -135 odds, with Alcaraz at +120, Medvedev at +900 and Shelton at +2800.
