Yamashita's lead cut to one stroke

Kim forces her way into Open title picture

- 

Japan's Miyu Yamashita faces a test of her temperament as she bids to win a first major title after her lead in the Women's British Open was reduced to one stroke on Saturday.

Yamashita, who was celebrating her 24th birthday, was three shots ahead going into the third round at Royal Porthcawl.

But having posted a bogey-free 65 on Friday, she carded a two-over par 74 following erratic driving off the tee and struggles on the greens at the Welsh links course to head into the final round on nine-under par.

“Today I'll be just looking at what went wrong and what went right and analysing the day and make the improvements that hopefully will lead to a better round tomorrow,” said Yamashita, whose best finish at a major came when she tied for second place at last year’s Women’s PGA Championship.
