Heather Watson became the first British women to reach the third round at Wimbledon for 10 years after beating world No.100 Jamie Lee Hampton in straight sets at the All-England Club.
Watson, whose win over Iveta Benesova on Centre Court on Monday was the first by a British women for 27 years, earned her first ever grand slam second round win with a faultless display against her state-side opponent.
Watson took just 26 minutes to claim the first set against Hampton, playing just her second match on grass following her first round win over 27th seed Daniela Hantuchova, as the American struggled with her serve on Court 3.
She was penalised for two foot faults in her opening service game, as Watson earned a double break on an overcast morning at SW19.
Hampton began to emerge into the contest late in the opening set, holding serve for the first time in the sixth game, but Watson hit the front in dominating fashion, not allowing the 22-year-old a sniff as she took the opening set 6-1.
The British No.4 began the second set like she started the first, breaking Hampton for a 2-0 lead, but quickly the American found a foothold in the match, taking the next two games to level the set.
Watson and Hampton then exchanged breaks in the middle of the second set, before a crucial hold in the eighth game, after being three break points down, opened the door for progression to the third round.
She eventually served it out, taking the set 6-4, showing maturity far beyond her years, and continues the wave of British success in the opening week of Wimbledon, which saw fellow women Elena Baltacha and Anne Keothavong both win their respective first round matches.
"I'm just so pleased to get through the match," she said. "It was definitely not easy. People might say it was a good draw but Jamie is a great player and she made it hard for me, she wasn't giving me anything. I knew I had to play my best. All I was saying to myself was don't double fault (having double faulted on her first match point). You have to go for it on those other points because the other girls aren't going to give it to you. The crowd were amazing, I was glad to win, not only for me but for them too."
The 20-year-old, who learned of her Olympic wildcard for London 2012 yesterday, will face either Agnieszka Radwansk or Elena Vesnina in round three.
