Catriona Matthew carded her second straight 71 Sunday to beat last year's winner Suzann Pettersen by a single stroke at the Ladies Irish Open.
Matthew finished at 7-under-par 209 for her fourth Ladies European Tour title.
Pettersen posted her second straight 3-under 69 to take second at minus-6, while Laura Davies closed with a 68 to end alone in third at 3-under-par 213.
The event was contested at Killeen Castle, which hosted the 2001 Solheim Cup, where the top three players on the leaderboard were teammates on the victorious European squad.
Matthew had two bogeys and three birdies through eight holes. She turned at minus-7. Matthew bogeyed the 14th, but came right back with a birdie on 15. At the 17th, Matthew converted a birdie try, but tripped to a bogey at the last to win by one.
Pettersen bogeyed the sixth and 10th, but in between had run off three straight birdies. She had three birdies in four holes from the 13th to close the gap, but stumbled to a bogey on 17.
Nikki Garrett (70), Joanna Klatten (70) and Pernilla Lindberg (75) shared fourth place at 1-under-par 215.
