Four of tennis' biggest stars are in action at the ATP Finals on Sunday.
The pregame narrative: Carlos Alcaraz has dominated Alex de Minaur, but there's value in backing the underdog. Elsewhere, I'm betting on Alexander Zverev to roll against Ben Shelton.

ATP Finals tennis predictions Nov. 9
Best Bet: Zverev -1.5 sets (+175)
A matchup between Zverev and Shelton should be electric, but I see the former dominating the latter.
Recent form plays a big part in making this pick. Zverev is coming off an excellent month of October, while Shelton is not.
The German tennis superstar advanced to the final in Vienna and the semifinals in Paris, crashing out with losses to Jannik Sinner at both.

Zverev earned some big wins in the process. He toppled Lorenzo Musetti and Daniil Medvedev last month.
Shelton didn't have a great October. He went an underwhelming 3-3, with two of his three defeats coming to lower-ranked opponents.
Shelton has proven to be a streaky player in 2025. The American star earned 18 of his 40 wins this year in July and August alone.
I'll gladly back Zverev to earn a convincing win at this price.
Key stat: Zverev is 4-0 lifetime against Shelton, beating him in straight sets on the hardcourt earlier this year in Cincinnati (6-2, 6-2).
Alcaraz vs. de Minaur best bet
de Minaur +1.5 sets (-107): This is not a matchup that has historically favoured de Minaur. He has lost all four head-to-head matches to Alcaraz.
So why am I backing the Aussie to keep it close?
This is a classic example of rest vs. rust, and I'll back the player who's playing some solid tennis ahead of this contest.
-> Bet on Alcaraz vs. de Minaur here
de Minaur played in 11 matches during October, going a solid 8-3 during that stretch with victories over top-50 players like Karen Khachanov, Gabriel Diallo and Nuno Borges.
Alcaraz, meanwhile, hasn't played much tennis as he works through an ankle injury. Alcaraz only played three matches last month, losing two of them.
de Minaur may not win this match, but I expect him to push Alcaraz.
