Dagny Brynjarsdottir and Hawa Cissoko scored second-half goals as West Ham secured a London derby win at Tottenham in the Women’s Super League.
Having missed a first-half penalty, Brynjarsdottir collected a loose ball and fired the visitors in front after 49 minutes.
Cissoko struck on a late counter attack for the Hammers, who look set to end the calendar year fifth in the WSL.
Defeat was Spurs’ third in a row as they stayed seventh.
The Hammers went three points ahead of Aston Villa, in sixth, who lost 4-1 to Arsenal on Sunday.
Victory means West Ham have now won three of their past four matches, bouncing back from last weekend’s loss to out-of-form Liverpool.
They were the better side at the Breyer Group Stadium in Leyton and were awarded a penalty when Spurs defender Kerys Harrop took out Kate Longhurst on the edge of the box on the stroke of half-time.
Brynjarsdottir’s spot-kick was poor, well wide of the target, although she would make amends with her goal shortly after the restart, her fifth in 10 WSL matches this season.
