Teenager Andy Murray gave British spirits a huge boost by destroying 14th seed Radek Stepanek 6-4 6-4 6-4 in front of a stunned crowd on Court One.
The 18-year-old took to the court as the only surviving Briton, following Tim Henman's earlier shock defeat.
But he responded to the pressure in superb style and once he broke serve after an epic rally at 4-4 in the first set, the result was rarely in doubt.
The Scot needed less than two hours to seal the biggest win of his career.
He later admitted Henman's five-set defeat to Dmitry Tursunov had motivated him.
"I knew Tim had just lost before I went on and I really wanted to keep the Brits going," he told BBC Sport.
"I knew they would give us a bit of hassle in the newspapers if I had lost as well."
He will now play 18th seed David Nalbandian in the third round, a match certain to be played on Centre Court on Saturday.
Murray added: "Hopefully it will be on Centre, it's been a dream of mine to play there."
The teenager had justifiably played down his hopes of victory against Stepanek, who at 14th, is ranked an incredible 299 places above the Scot.
But the difference in class was never apparent, even though Murray was playing in only his second Grand Slam match and his sixth as a professional.
Murray saved break points at 2-3 and 3-4 in the first set, before he eventually wore Stepanek down.
Once the Briton earned his first break point, he took it brilliantly.
In an epic rally, the Scot twice looked out of the point but scrambled the ball back and Stepanek finally crumbled, giving Murray an easy put-away.
Making his first appearance on one of Wimbledon's two main courts, Murray might have been nervous as he emerged to serve for the opening set, but he took it with ease, finishing with an ace and a roar of determination.
Things only got better after that as the 18-year-old broke serve at the start of the second set and then forged a 5-1 lead.
He faltered slightly when serving for the set at 5-2 but made no mistake two games later.
Murray later admitted that he had woken on Thursday morning with a "sore head and a sore stomach" and felt ill again at the end of the second set.
But it did not show in his performance as he closed on victory by breaking for the fourth time at 1-1 in the third set.
Stepanek, normally an indefatigable competitor, was by now shell-shocked and put up scant resistance.
Murray was unlucky to see two match points pass by at 5-3 but he shrugged off the disappointment to wrap up a hugely impressive win in the next game.
The Briton later said Stepanek, who has been accused of gamesmanship in the past, had tried to put him off.
"I was a bit annoyed at him at the end," he said.
"He was trying to put me off and make me nervous but it didn't work and he ended up looking a bit stupid."
