Wimbledon 2018: Uncanny English Bettor Releases Quarterfinal Picks

The Wimbledon quarterfinals are set. Top-seeded Roger Federer and Novak Djokovic are big favorites, while Rafael Nadal gets an extremely tough test against Juan Martin del Potro. No. 9 John Isner plays No. 13 Milos Raonic in a virtual toss-up.

Before you make your picks 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 2013 and 2016, he called Andy Murray winning Wimbledon despite Djokovic entering as the favorite. This year he's 11-6 in Wimbledon bets, including big underdog winners like Haase-Copil to go Over 1.5 tiebreaks.

Before Wimbledon, Calvert cashed in huge on John Isner at 100-1 to win the Miami Open. 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 Federer gets a tougher-than-expected match against Kevin Anderson, noting Anderson is much more confident now than he was the last time they met. "They haven't clashed since 2015 and never on grass, the surface on which Anderson has held serve 93.6% of the time in his last 10 matches, and Federer hasn't looked quite like the player he was so far on grass this season. 

Calvert has one more bet locked in for Federer-Anderson, plus recommendations on Djokovic-Nishikori, Nadal-del Potro and Isner-Raonic. He's gunning for several plus-money payouts. Anyone who follows him could be in for a huge Wednesday.
