Stan Wawrinka lost in the first round of Wimbledon to a 21-year-old who had never won a Grand Slam match

It didn't take long for the first shocker of Wimbledon 2017, as three-time Grand Slam champion Stan Wawrinka lost on opening day to unseeded Daniil Medvedev in four sets on Centre Court.

The win was Medvedev's first in a Slam as well as his first career win against a top-ten opponent. The 21-year-old Russian will face Ruben Bemelmans in the second round on Wednesday.

As for Wawrinka, the runner-up in this year's French Open, it was the earliest exit from the tournament since 2013. It's a tough result for the 32-year-old, who is only a Wimbledon title away from a career grand slam. It will surely be his toughest fought title should he eventually win it. Since 2003 only four men - Federer, Nadal, Djokovic, and Murray - have won Wimbledon.

After the match, Medvedev was clearly delighted to have secured the biggest win of his young career. "I'm just really happy," Medvedev said. "My first grand slam win. I mean, Centre Court of Wimbledon."
