Stan Wawrinka knocked out of Wimbledon 2017 by Debutant Daniil Medvedev

Swiss fifth seed and French Open runner-up Stan Wawrinka was knocked out of Wimbledon in the first round by Russia's Daniil Medvedev on Monday, losing 6-4, 3-6, 6-4, 6-1.

World number 49 Medvedev, making his Wimbledon debut, goes on to face Belgian qualifier Ruben Bemelmans for a place in the last 32.

It was Wawrinka's sixth first round loss at the All England Club, although his efforts were hampered by a left knee injury which required an ice pack at the changeovers.

Having lost in the first round at Queen's Club last month, Wawrinka's grass-court campaign amounted to two matches and two defeats.

For 21-year-old Medvedev, it was a first win at the Grand Slam level, coming on the back of an impressive grass court season.

He made the semi-finals in Eastbourne last week where it took Novak Djokovic to stop him, as well as the quarter-finals at 's-Hertogenbosch and Queen's.

"A year ago I was ranked 250. If someone told me in one year I would win on Centre Court I would tell you you are joking," said Medvedev, who kissed the grass of Centre Court to celebrate his victory.
