Top seed Deta Hedman says many female players have performed below their best in the first round this year.
The 54-year-old Oxfordshire player beat Lorraine Farlam 2-0 in her opening match and her average of 83.69 was almost 11 points higher than any of her fellow competitors.
“We’ve played so well all year, but we haven’t really produced what we can do,” she said.
“When you come to Lakeside, it does something to you.”
In today’s second round, Hedman faces Germany’s Irina Armstrong, who saw off Sharon Prins, of Holland, 2-0.
