Leinster won the women's interprovincial golf championship for the fifth successive year when they came through unbeaten on the final day at Killarney yesterday. Ulster won two of the three matches for second position, leaving Munster next with one win and Connacht taking the wooden spoon.

The decider yesterday was at one stage a very close affair with Leinster finally getting through to beat Munster by 4 1/2 to 2 1/2, taking the last three of the seven matches.

Because the greens were flooded and the first day's play had to be called off, the competition was decided over singles on Thursday and yesterday. In the top pairing yesterday between two former Irish champions, Suzanne O'Brien (Milltown) got up and down from a bunker at the last hole on the O'Mahony's Point course to square the match with Eileen Rose Power. The Munster player was two up playing the 14th but the Milltown golfer won the next two in birdies to level matters.

There was another gripping tussle between two young newcomers when the Longford-born university athlete Deirdre Smith (Co Louth) beat Munster's Aida Burke (Charleville) on the last green. With birdies at the first and fifth , the Co Louth player went two up but lost the seventh when the Charleville girl hit a great sixiron to within 10 feet of the pin for a birdie to turn only one down.

Smith birdied the 15th to go two up again but a birdie reply from Burke, when her opponent was in the trees, brought the match back to one and they both had great pars at the finishing hole by the lake.

Munster's two winners were Irish champion, 19-year-old Clare Coughlan (Cork) the only unbeaten member of the team, and Valerie Hassett (Ennis). The Cork youngster was most impressive in beating Elaine Dowdall (Wexford) at the 14th. The Ennis golfer won the first three holes against Sinead Keane (Curragh) and was four up at the turn. The only hole won by the Leinster player was the 14th and she conceded the match at the next.

Leinster's unbeaten players were Suzanne O'Brien, Deirdre Smith and Oonagh Purfield.

Ireland finished a disappointing Boys' Home International Championship at Conwy in North Wales yesterday with the wooden spoon. After defeats by Scotland and England, they crashed to a heavy reverse at the hands of Wales 101/241/2. England retained the title and completed the triple crown when they narrowly beat Scotland 8-7.
