(CNN) -- Catriona Matthew of Scotland carded a hole in one as she shared the halfway lead with Giulia Sergas of Italy in the women's British Open at Royal Lytham on Friday.
Matthew swung sweetly during her second round 67 at Lytham.
Matthew followed an eagle at the 11th with an ace at the short 12th on the seaside links on the way to a five-under 67.
Sergas, who also carded a 67, joined Matthew on three-under 141, making five birdies on the back nine.
Yuko Mitsuka (71) was the nearest challenger, a shot back in third. Song-Hee Kim (73) was on 143, a stroke ahead of Yani Tseng (70) and Christina Kim (71).
Matthew and her husband Graeme had a dramatic escape when their French apartment block was hit by a fire while she contested last week's Evian Masters.
Graeme had to miss the tournament, suffering from burns to his feet, but was back on his wife's bag for their home women's major.
"It was very scary, and we kind of panicked," she said recounting the incident.
World number one Lorena Ochoa continued her dismal form in England with a five over 77 to be eight over for two rounds but inside the cut mark with scoring high.
First-round leader Sandra Gal of Germany fell away with an 80 while Angela Stanford of the United States, who was joint second after the first round, fell away with a 76.
Other big names also struggled with Paula Creamer following a 75 with a 74 and is on the same mark as defending champion Jiyai Shin.
Michelle Wie carded a 75 to be one further back and eight out of the lead. She needed two to get out of a fairway bunker on the 18th to stall her challenge.
Gwladys Nocera, last year's European Tour number one, made a remarkable 17-shot improvement with a second round 74 after her horror round of 91 on the first day.
Meanwhile, in the Czech Open on the men's European Tour, England's Steve Webster and Graeme Storm lead the way on eight-under 136.
