Title holder Murdoch shares lead
Murdoch carded a birdie at the 7th to turn level par and following bogeys at 11 and 13, she birdied 16 to cap a strong opening round in sunny but breezy conditions. Nearest rival Noreen Fenton from Merchants of Edinburgh birdied 1 and 7 to turn one under par and after a double-bogey at the short 13th she completed her see-saw round with birdies at 16 and 17 to tie Murdoch's 75. Canadian Judy Collins is one shot further back on 76 after a 1 under back nine.
Milltown's Rhona Fanagan leads the Irish challenge with a three over par 77 having carded double-bogeys at 10 and 17.
