Leaders Chelsea extended their unbeaten run in the Women's Super League to 33 games with a comprehensive 4-0 win over London rivals Tottenham.
Germany international Melanie Leupolz scored twice as she added a second-half penalty to her first-half opener, while Abbie McManu scored an own goal before Matildas skipper Sam Kerr headed home her ninth league goal of the season.
Tottenham's loss to Chelsea was their first under manager Rehanne Skinner.
First-half goals from Ella Toone and Christen Press earned Manchester United a 2-0 win at Everton and kept them level on points with Chelsea.
After a competitive start, Toone put the visitors ahead in the ninth minute with her sixth WSL goal of the season. She pounced on a loose ball in the six-yard box after a Leah Galton cross was only parried by goalkeeper Sandy MacIver and fired home with her left foot.
United's second goal also came from an error in the Everton defence. A failed clearance fell to Hayley Ladd who played it forward to Press. She held off a defender, took the ball into the box and slotted past the keeper.
Manchester City scored twice in each half as they brushed aside West Ham 4-0 at the Academy Stadium.
Third-placed City made a host of changes in the final stages which slowed their momentum as they remained five points behind the leading pair.
The game between Aston Villa and Arsenal was postponed due to a waterlogged pitch.
