Ireland followed a first day win over England with a 7½-1½ victory over Wales to stay on course for a successful defence of the Ladies Home International title at Ballybunion.
Backed by the home crowd, Ireland face a final day tie against Scotland, who suffered a narrow 5-4 second day loss to England. A draw will be enough for the hosts.
England produced a gritty effort to edge out Scotland by the single point. In the final game, Lianna Bailey won the 16th and 17th holes to defeat Eilidh Briggs by 2&1. Nicola Slater had also won on those same holes in beating Gemma Batty by the same margin.
England claimed the foursomes convincingly 2½-1½ but Captain Elaine Ratcliffe was relieved to steer her side over the winning line.
“We just clung on,” she admitted. “This is a great golf course and if you can get to the last three holes and still have a chance then anything can happen and we proved it today. But Scotland played really well and should make it tough for Ireland.”
In the Girls Home Internationals, defending champions England beat Scotland 7-2 and face Wales, 5½-3½ winners over Ireland, in the round three title decider.
