Arsenal coasted to a 4-0 win at Bristol City to extend their unblemished start to the Women's Super League season.
First-half goals from England international Jordan Nobbs and Vivianne Miedema set up a sixth straight win.
Holland striker Miedema claimed her 11th goal of the season two minutes from time and Danielle van de Donk fired home the fourth in stoppage time.
New Liverpool boss Vicky Jepson lost her first official match in charge as Chelsea won 1-0 at Kingsmeadow.
Magda Eriksson secured a second win of the season for the reigning WSL champions with a 27th-minute overhead kick.
Jepson took charge after being appointed officially as manager on Friday, having done the job since the departure of Neil Redfearn in September, but Chelsea leapfrogged them into fourth.
West Ham moved above opponents Everton into eighth spot with a 2-1 comeback win at Southport.
Claudia Walker gave Everton an early lead, but Jane Ross - who later saw her spot-kick saved by Kirstie Levell - and Alisha Lehmann put the Hammers ahead before the break.
Brighton claimed their first top-flight scalp by beating Yeovil 2-1 in the battle of the bottom two.
Jodie Brett and Victoria Williams gave Brighton breathing space at the break, and Yeovil remain pointless after six games despite Ellie Mason's second-half effort.
