The Toffees claimed a 3-2 victory over Reading in their first match of 2023, while West Ham United were narrowly beaten by Manchester City last weekend.
Match preview
After beating Tottenham Hotspur 3-0 in their final league game of 2022, Everton began the new year with another three-goal haul.
Katja Snoeijs and Jess Park both found the net to give Everton a 2-0 lead at half time of their home meeting with Reading last weekend, before the Royals halved the deficit through Justine Vanhaevermaet on the hour mark.
Within a minute, Gabby George opened her account for the season to restore Everton's two-goal advantage, although Deanna Cooper reduced the deficit in the 68th minute, the Toffees held firm to secure a 3-2 win.
As a result of that victory, Brian Sorensen's side moved up to fifth position by virtue of their superior goal difference over West Ham, which represents a sign of progress for the Toffees, who finished last season in 10th place.
After winning their last two league games, Everton now have the chance to record three consecutive WSL victories for the first time since October 2020.
Following a 2-0 away win over Tottenham before the winter break, West Ham would have been looking to claim two straight wins when they faced Manchester City last weekend.
Unfortunately for the Hammers, they were edged out by the Citizens following Khadija Shaw's second half strike, although Paul Konchesky would have taken confidence from his team's performance against a Man City side chasing Champions League qualification.
Unlike Sunday's opponents, West Ham were also in action in midweek, playing out a goalless League Cup draw against fellow WSL side Brighton & Hove Albion, who beat the Hammers on penalties to claim a bonus point.
West Ham still managed to finish top of their League Cup group, and they will now face Liverpool in the quarter-finals on Wednesday, but their current focus will be on Sunday's fixture, where a win would move them above Everton.
The visitors also have the chance to claim a league double over the Toffees after winning 1-0 in the reverse fixture on the opening weekend of the season.
