Heather Watson made Centre Court her stage as she thrashed experienced Czech Iveta Benesova for her first Wimbledon win.
The 20-year-old from Guernsey had to wait until the evening to see where her match would be played, and had little time to prepare for her debut on tennis' most hallowed arena.
But she looked as if she had been playing there her whole career as she raced to a 6-2 6-1 victory.
Watson said: "I'm so pleased to have got through that. It was tough not knowing when I was going to be on but it worked out pretty well for me.
"This is my first singles win at Wimbledon including juniors so I'm so pleased. The crowd was amazing."
Watson has played twice in the main draw at Wimbledon before, both times losing close encounters, but she is full of confidence after reaching the second round of the French Open and showing good form on grass.
The British number three has added extra weight to her groundstrokes and her serve and she wasted little time making headway on world number 55 Benesova, racing into a 4-1 lead.
The 29-year-old Czech has a poor record at Wimbledon, winning only three main-draw matches in 10 attempts, but that was to take nothing away from Watson, who had a number of chances to move 5-1 ahead.
She could not take them, but it did not matter, the former US Open junior champion simply breaking on her next opportunity to take the set.
There was no danger of her letting the momentum go at the start of the second set, Watson breaking again in the second game and then, after a lengthy battle, moving into a 5-1 lead with a forehand winner down the line.
The young Briton had not so much as faced a break point all match but, with the finishing line in sight, she tightened a little and Benesova had her first two chances.
She could not take them though, and Watson brought up her first match point with an ace before clinching victory when Benesova fired a return long.
It was the same scoreline by which Benesova lost to another British player, Tara Moore, at the AEGON Classic in Birmingham two weeks ago and represented a landmark win for Watson, who next faces America's Jamie Hampton.
