Laura Davies wins in Norway
Larraneta, with only one top five in five years on the European Tour, shot a great final round four under 68 to set a clubhouse target of five under 283 that only Davies, who dropped a shot at the 17th in a 73, could match.
In the play-off over the 18th hole, both players made par at the 18th the first time round, but Davies clinched the £33,000 top prize by holing from five feet for birdie the second time.
