Stan Wawrinka is one of the few players to win a Grand Slam in the last 10 years and not be a part of the Big 3 or Big 4.

Next to Roger Federer, Novak Djokovic, Rafael Nadal and Andy Murray, Wawrinka has been the closest to being the best on tour in terms of Grand Slams and titles won. In January 2014, he even climbed up a career-high ranking of world No. 3.

Wawrinka's last Grand Slam quarterfinal appearance was this season at the Australian Open, losing to Alexander Zverev. With the Swiss always the dark horse in any draw, it's important to understand the history of his achievements.
