British qualifier Marcus Willis - ranked 772 in the world - caused a huge upset with victory over world number 54 Ricardis Berankis at Wimbledon.
Roared on by a vocal pocket of supporters on court 17, Willis saw off Lithunania's Berankis 6-3 6-3 6-4.
Willis, who came through six rounds of qualifying to earn his debut at the All England Club, could now face seven-time champion Roger Federer in round two.
The 25-year-old from Slough guarantees himself £50,000 in prize money.
On an opening day when his compatriots struggled, it was the unlikely figure of Willis who got the first British win on the board.
