Teenager Charley Hull was not the only home amateur to shine as the Ricoh Women's British Open got under way at Hoylake.
The Woburn youngster, tricking herself into thinking she was "out there with my mates", tucked in just behind the two leaders with a one under par 71, the same as Wales' Lydia Hall.
Then Curtis Cup team-mate Holly Clyburn, who also came through Monday's qualifier, matched the 72 of Taiwanese star Yani Tseng, the world number one chasing an unprecedented third successive victory in the event.
South Korean pair Haeji Kang and So Yeon Ryu - last year's US Women's Open champion - set the pace on two under after a day which also saw 1986 winner Laura Davies, playing her 100th major, fail to break 80.
Ranked the world's eighth best woman amateur, 16-year-old Hull birdied the second and fifth and although she failed to add to them her only bogey came on the 382-yard eighth.
Hull, who would have played at Carnoustie last year but for triple-bogeying the final hole of qualifying to miss out by one shot, finished 38th on her major debut at the Kraft Nabisco Championship in California in April and has so far been undaunted by the big stage.
"I wasn't nervous on the first tee because I didn't have any expectations," she commented. I just pretend I'm out there playing with my mates. I know it's a major, but that's how I think of it.
"I didn't drive it that great, but I still managed to hit fairways."
Asked if she thought she could win Hull replied: "It's possible, but I'm not thinking of that at the minute."
Clyburn, a 21-year-old from Cleethorpes, out-scored playing partner Karen Stupples, the last English winner of the title eight years ago, by four.
Despite feeling "quite calm" she bogeyed three of her first six holes, but then birdied the 16th, 18th - both par fives - and eighth, where her seven-iron finished nine feet from the flag.
America's best-known woman golfer Michelle Wie double-bogeyed the first hole and had to be content with a 75, but that was still two better than her playing partner Carly Booth, leading money-winner on this season's Ladies European Tour.
Fellow Scot Catriona Matthew, winner at Royal Lytham three years ago, shot 76 and England's Melissa Reid, the Solheim Cup player whose mother was killed in a car crash in May, was another to return a 77.
Fifteen-year-old New Zealand amateur Lydia Ko, who last month in Canada became the youngest-ever LPGA Tour winner, remained very much in the hunt with a 72, however.
