Heather Watson made Centre Court her stage as she thrashed experienced Czech Iveta Benesova on Monday 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.
Meanwhile Britain's Naomi Broady only had herself to blame as she made a first-round Wimbledon exit at the hands of Lourdes Dominguez Lino.
The 22-year-old from Stockport was always likely to be up against it against the Spaniard, ranked some 157 places above her in the world, but had more than her fair share of chances in a 6-4 7-6 (7/4) defeat.
Unfortunately for her, though, an unwanted trait of failing to capitalise on her first-set chances cost her and she was condemned to a second successive first-round knockout.
The warning signs had been there from the off, with three break points having to be saved in the first game, before Dominquez Lino cashed one in to go 2-1 ahead.
But Broady served out her next two games to love and 15, setting herself up to break back to 4-4.
But she offered up another break point in the ninth game, which was duly taken, although when Dominquez Lino went 0-40 down when serving for the set, Broady looked to have a route back in.
She was unable to take it, however, meekly squandering all three break points and when she netted on set point, her opponent moved ahead.
The second set was a more routine affair, with serve holding sway all the way through to a tie-break which Broady kicked off with a mini-break.
Again, though, she was unable to make the best of her leg-up and from 2-0 up slipped to 5-2 down, with Dominquez Lino seeing things out and moving through to a meeting with Sorana Cirstea.
Afterwards, Broady conceded she had let the game slip away from her at crucial moments.
"I felt like it was really close and it just wasn't quite there," she said.
"I had a few chances and made some mistakes which is really annoying to look back on.
"There's nothing I can do about it now. I'll just take the positives from it."
Johanna Konta's Wimbledon debut against Christina McHale was left on a knife-edge after play was suspended due to fading light with the players locked at 7-7 in the third set.
Konta, who was born in Australia but now represents Britain after receiving citizenship last month, defied all expectations to win a first-set tie-break against McHale, who at 32nd in the world is ranked 180 places above her.
The 21-year-old British number five dropped the second set 6-2, and her American opponent looked set to ease to victory in the decider when she broke Konta in the first game.
Konta was on the verge of defeat after she initially failed to break back, leaving McHale serving for the match at 5-4.
McHale buckled under pressure, however, allowing Konta to smash home at the net to level the set.
The pre-match favourite soon rallied, however, breaking Konta immediately to give her another chance to serve for the match.
She buckled yet again, however, forcing McHale to find the net to leave the match at 6-6.
Both players then tentatively held serve until the umpire postponed the game until Tuesday as the light worsened on Court 17.
