(Reuters) -Japan's Miyu Yamashita celebrated her 24th birthday by maintaining her grip on the Women's Open lead but it was hardly the smooth ride she might have hoped for after a stuttering 74 in the third round at Royal Porthcawl on Saturday.
Yamashita, who had surged into a three-shot lead on Friday with a sparkling seven-under 65, found herself in a much scrappier battle where she carded four bogeys to slip back to nine-under overall.
