Dominic Thiem and Alexander Zverev collide on Sunday in the men's final of the 2020 U.S. Open in Flushing, N.Y. Thiem is a -400 favorite in the odds from William Hill while Zverev is +300. The match begins at 4 p.m. ET.

Before you make any picks on who wins the men's title, you NEED to see whom Sean Calvert is picking.

Calvert is the famed handicapper who took down a huge score on 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 Novak 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 for his fifth Wimbledon crown. Anyone who followed Calvert's advice was handsomely rewarded.

And Calvert owns the U.S. Open. Since 2013, if you had placed $100 on each of Calvert's recommended bets, you'd be up a whopping $8,540.

For Sunday's men's final, we can tell you Calvert is not expecting a straight-sets victory by either Thiem or Zverev. 

Instead, Calvert has targeted a single bet that pays plus-money and offers excellent value. You NEED to see his picks and analysis before you consider betting the final.
