Rafael Nadal can join Roger Federer atop the list for the most grand slam singles titles in a career when he takes on Novak Djokovic in the 2020 French Open men's singles final on Sunday on Court Philippe-Chatrier at Roland Garros in Paris. First serve is 2 p.m. ET. William Hill lists Nadal as a -150 favorite, with Djokovic listed at +120. Before you make any picks on this must-see match, you NEED to see whom Sean Calvert is picking.

Calvert is the famed handicapper who took down a huge score on Dominic Thiem winning Indian Wells at 80-1 last year, among many stunning calls. He's racked up seven straight profitable seasons betting tennis. 

At Wimbledon last year, Calvert told his followers to grab 3-1 odds on Djokovic facing Roger Federer in the final, adding Djokovic would win it all. The result: Djokovic and Federer cruised into the finals, with Djokovic winning the longest men's singles final in tournament history. Anyone who followed Calvert's advice was handsomely rewarded.

Now, Calvert has released three best bets for Djokovic vs. Nadal. We can tell you that Calvert likes the Set 1 score to be 6-4, a wager that's +240 at William Hill.
