Chelsea returned to Women's Super League action after the winter break with a bang, moving seven points clear at the top of the table after a 5-0 win over West Ham.
The Blues, who saw their perfect start to the league campaign ended by a 1-1 draw with Leicester City last time out, were out of sight at half-time.
Catarino Macario opened the scoring 11 minutes in at the Chigwell Construction Stadium, volleying beyond Kinga Szemik, before Erin Cuthbert drilled in a long-range second.
Aggie Beever-Jones was on target with her fifth goal of the season just before the break, firing her own strike past the goalkeeper from outside the box.
Sandy Baltimore got in on the act seven minutes after the break before Amber Tysiak inadvertently turned into the back of her own net and past a hapless Szemik, subjecting West Ham, who are 10th, to a seventh defeat of the season.

With Manchester City not playing until later on Sunday when they face rivals Manchester United, Arsenal moved second in the WSL table, also registering a thumping 5-0 victory over bottom-of-the-table Crystal Palace.
In Renee Slegers' first match in permanent charge, the Gunners continued their unbeaten start under the Dutchwoman, with Leah Williamson getting them off the mark six minutes in from close range.
My Cato missed a golden chance to equalise for the hosts in the first half, and that was punished in the second as the hosts ran riot.
Two goals in four minutes from Alessia Russo and Beth Mead just past the hour ensured the points for Slegers, but Mariona Caldentey added some gloss to the scoreline.
She coolly converted from the spot in the 75th minute after Annabel Blanchard clumsily brought down Caitlin Foord, before curling in a low effort after Russo's strike rebounded off the post in stoppage time.
Tottenham also got three points on the board, edging to a 1-0 win over Leicester in Sunday's early kick-off at the Gaughan Group Stadium.
The damage was done in the fourth minute as Janina Leitzig's own goal gifted Spurs a winning start to the year, turning in Amanda Nilsen's deflected cross.
Leicester's profligacy came back to haunt them once more. The Foxes have netted just three times this season but should have added to that tally, Janice Cayman missing an open net from six yards out, while Missy Goodwin forced a good save out of Lilywhites debutant Liza Kop.
It means Leicester stay just one point above Palace in 11th.
