Fifteen-year-old American qualifier Cori Gauff caused a stunning upset by defeating five-time Wimbledon champion Venus Williams in the first round.
World number 313 Gauff beat Williams - 24 years her senior at 39 - 6-4 6-4.
Fellow American Williams had won four Grand Slam titles - including two at Wimbledon - before Gauff was born.
"It's the first time I have ever cried after winning a match," said Gauff, who previously said Venus and sister Serena were her "idols".
"I don't know how to explain how I feel."
Williams turned professional 10 years before her opponent was born, with Gauff being the youngest player to qualify for the main Wimbledon draw since the Open era began in 1968.
"I definitely had to tell myself to stay calm, I had to remind myself that the lines are the same lines, the courts are the same size and after every point I told myself 'stay calm'."
"Venus told me congratulations and keep going, she said good luck and I told her thanks for everything she did," Gauff added.
"I wouldn't be here if it wasn't for her - I told her she was so inspiring and I've always wanted to tell her that but I've never had the guts to before.
"My parents will be super happy, my dad was jumping up every time I won a point. I'm so happy they spent all their time on me and my brothers and making sure we're successful.
"I never thought this would happen. I'm literally living my dream right now.
"I'm really happy Wimbledon gave me the chance to play, I never thought I would get this far."
