Wimbledon 2021 will begin on June 28 and with great anticipation. After the event was cancelled due to the pandemic in 2020, tennis observers are ready to take in the action in London and watch the 2021 Wimbledon field battle it out. On the men's side of the Wimbledon 2021 bracket, Novak Djokovic is the top story as the No. 1 player in the world and two-time reigning champion.

Djokovic enters at -110 (risk $110 to win $100) in the latest 2021 Wimbledon odds from William Hill Sportsbook. He is the clear 2021 Wimbledon favorite, though Daniil Medvedev and Stefanos Tsitsipas both come in at +600. After that, there is a familiar face in Roger Federer at +800. Before making your men's 2021 Wimbledon picks or predictions, you need to see who tennis expert Sean Calvert is backing.

Calvert is the famed handicapper who called Stan Wawrinka winning the 2014 Australian Open at 60-1. In 2019, Calvert took down a huge score on Dominic Thiem winning Indian Wells at 80-1, among many stunning calls. Anyone following his tennis picks is way up.

Now, Calvert has scrutinized the latest Wimbledon 2021 odds and released his coveted best bets to win it all. He's sharing all of his expert picks and analysis at SportsLine.

There are big names in the mix at Wimbledon and many could be seen as appealing in the betting market. However, Roger Federer is one of Calvert's fades for the tournament. That may sound odd given Federer's overwhelming success at the event, but Calvert points to his recent form as reason for concern.

Calvert does admit that "the Federer name is a massive help to him" and he can "win matches largely on reputation alone." It takes more than that, though, to win at the highest levels. In the end, Calvert makes the case that the price is simply too short at +800.

Instead, Calvert is backing an underdog who will have history and the 2021 Wimbledon draw on his side. He's sharing who it is, and all of his Wimbledon 2021 expert picks and predictions only on SportsLine.
