Wimbledon's first real shocker came early this year. The World No. 3 Stan Wawrinka suffered an upset in the first round on Monday, at the hands of Russia's Daniil Medvedev. Medvedev, the 49th-ranked player in the world, has had a stellar season on grass, and he handled a hobbled Wawrinka 6-4 3-6 6-4 6-1. Wawrinka was seeded fifth in the tournament, and he was icing his knee at time throughout the contest.

The loss marks Wawrinka's first first-round exit at a Slam event since the 2014 French Open. He is still yet to make it past a quarterfinal at Wimbledon, the only Slam that he perennially seems to struggle at. 

Meanwhile, it's Medvedev's first Wimbledon appearance, and it's certainly one that he'll never forget. "Right now I don't even know what I have to say," he said. "Wimbledon is my favourite Slam -- it was in juniors and it still is. Even one year ago I was 250 in the ranking. If then someone had told me I would play, never mind win, on Centre Court at Wimbledon, I would say they were joking. I knew Stan had some problems at Queen's and I knew I would have some chances."

Medvedev took every chance that was presented, forcing Wawrinka to stay mobile on his knee. Wawrinka was unable to keep up and never played up to his normal skill level, which Medvedev capitalized on time and time again. After the match, he gave the Centre Court a kiss, and made his way off to prepare for the Round of 64. It only gets more difficult from here on out, but for a player that's considered to be "making his way into" tennis's ranks, this was an excellent coming out party.
