On centre court at Wimbledon this evening, the world number 772 takes on one of the great players of all time - Roger Federer.
Marcus Willis pulled off a major upset on Monday when he beat Ricardas Berankis, the world number 53 to set up a second round match with Federer.
It guaranteed Willis a cheque of £50,000, a considerable amount when you consider that so far this year, the Englishman has earned just £220. Getting to that match with Berankis was an achievement itself, Willis had to win six matches just to enter the main draw.
One set down to Federer, it took Willis until the second set to win a game against the world number three.
When he did win that game, the Wimbledon crowd erupted.
Willis lapped it up too, approaching the net like he had just won the tournament.
