The world no.772 is currently taking on Roger Federer on Centre Court at Wimbledon, after making through to the Grand Slam’s second round earlier this week.
Willis is the ultimate underdog, having came through six rounds of qualifying before defeating the world no.54 Ricardis Berankis on Monday – much to Andy Murray’s delight.
And the 25-year-old was handed a dream draw in what could be his first, last and only match on Wimbledon’s big stage against the 18-time major winner, and seven-time winner at the London event.
Federer swiftly reminded Willis where he was by claiming the first set 6-0, but Willis composed himself to lose the second set just 6-3, before claiming the lead twice in the third set.
His mini heroics and charismatic attitude seemed to entertain just about everyone watching:
Marcus Willis definitely making the most of this occasion!! Can't stop smiling #Wimbledon2016 ?

Federer v Marcus Willis on Centre Court. Willis is ranked number 23 in Britain. To put that in context Sue Barker is still ranked 15th.

The England football team could learn from Marcus Willis. We totally expect you to lose but you gain respect for giving it your best.
