Sam Kerr and Beth England combined for both goals as Chelsea eased past West Ham 2-0 to maintain their lead at the top of the Women's Super League.
Kerr headed in England’s cross for her 12th league goal of the term, before teeing up England in returning the favour after the break.
Republic of Ireland international goalkeeper Courtney Brosnan played the full game for the Hammers.
Chelsea remained two points clear of Manchester City, who needed a fine goal from Keira Walsh to see off Everton 1-0.
Walsh’s 20-yard strike broke the deadlock in the final 10 minutes, as City sealed their ninth-straight WSL victory to top the table for an hour – only for Chelsea to overhaul their rivals again with that win over West Ham.
Manchester United secured third place with a comfortable win over Aston Villa, with Kirsty Hanson, Jess Sigsworth and Katie Zelem all on target.
Katie McCabe set up a goal as Arsenal beat Birmingham City 4-0. City were captained by Harriet Scott, who played the full game, as did international team-mate Ruesha Littlejohn.
Caitlin Foord struck twice in three minutes with Vivianne Miedema and Lisa Evans also finding the net for the Gunners.
Meanwhile, Megan Connolly was booked in Brighton's 2-0 win over Tottenham, with Inessa Kaagman’s double helping Spurs to their third league win in a row.
Connolly's Ireland colleague Rianna Jarrett came on for a cameo in second-half stoppage time.
