Wimbledon 2018: Uncanny English Bettor Releases Semifinal Picks

The Wimbledon semifinals are set. Surprising Kevin Anderson takes on John Isner at 7 a.m. ET Friday, then two-time champ Rafael Nadal plays three-time champ Novak Djokovic in a titanic matchup. Oddsmakers view both matches as dead-even, with all four players listed at -110 to win.

Before you bet on the sides, total games or various props, you have to hear what British tennis expert Sean Calvert says. An Essex resident, Calvert has been releasing documented, profitable bets for six straight years, and he owns this event in his home country. In Wednesday's quarterfinals, Calvert knew Roger Federer would be in for a long day vs. Kevin Anderson. The result? Calvert cashed big on Over 33.5 games and Anderson +6 games as Federer shockingly went down in a five-set thriller.

Calvert also nailed +120 underdog Isner beating Milos Raonic and cashed +137 on no tiebreaks in Djokovic-Nishikori. For the tourney, he's up nearly $700. In 2013 and 2016, Calvert called Andy Murray winning Wimbledon despite Djokovic entering as the favorite each time.

Before Wimbledon, Calvert struck it rich on Isner winning the Miami Open at 100-1. Calvert's legendary calls include Stan Wawrinka to win the 2014 Australian Open at 60-1 and Jack Sock to win the 2017 Paris Masters at 80-1. Anyone who has followed him is way, way up.

We can tell you Calvert thinks the first set of Isner-Anderson won't go to a tiebreak, a bet that pays +200 considering both have monster serves. But his bigger play is on the must-see Nadal-Djokovic match.
