U.S. Open 2018: Uncanny Bettor Releases Sunday Championship Picks

Former U.S. Open champs Juan Martin del Potro and Novak Djokovic collide Sunday in the men's final at Billie Jean King National Tennis Center in New York.

Before you pick this must-see match, you have to hear what international tennis expert Sean Calvert says. Calvert destroyed the books in the U.S. Open quarters and the semis, saying Djokovic would absolutely dominate Kei Nishikori. Calvert recommended betting Nishikori Under 15.5 games (he won nine); betting the first set to go Under 9.5 games (it lasted nine); and betting the match would have zero tie-breaks (there were none). Anyone who's following Calvert this tournament is way, way up.

In fact, Calvert owns this event. In 2013, he nailed 25 of 28 U.S. Open bets -- an insane 89.3 percent win rate that netted his followers nearly $2,700. The next year, his followers won $1,700. In 2015, Calvert called Flavia Pennetta's shocking women's title and it paid off at 499-1! At this year's Wimbledon, Calvert again made history by predicting Roger Federer's stunning quarterfinal loss.

And of course, Calvert cashed in huge on John Isner at 100-1 to win the 2018 Miami Open!

Now, Calvert has broken down the 2018 U.S. Open final and locked in his bets. We can tell you Calvert is calling for a riveting final you don't want to miss, noting: "Neither man has really been seriously tested (unless you count by the conditions) this tournament so far, so they should each have enough gas in the tank to make this an entertaining final."

He's highly confident he has the winner, plus he's throwing in prop bet recommendations too.
