NWSL weekend preview: What's in store for your Westfield Matildas?

Could the National Women's Soccer League title race be any closer?

Probably not. With the top four separated by just two points ahead of this weekend's round of fixtures, the margin for error grows continually slimmer for our title-chasing Westfield Matildas in America.

What's the state of play for our Australian stars? Read on to find out.

All kick off times in AEST.

Kerr's Red Stars can take top spot on Sunday morning

First up, Sam Kerr and Mackenzie Arnold of Chicago Red Stars can seize top spot with a win over Washington Spirit on Sunday morning, kick off 9:00am. 

Kerr - who won her fifth Player of the Week award of the season this week - has been in red-hot form for Chicago, who enter the clash with Spirit on a four-match winning streak.

It poises a tough assignment for three Washington Spirit players who know the Australian super star better than most, in Westfield Matildas teammates Chloe Logarzo, Elise Kellond-Knight and Amy Harrison.

The Red Stars would leapfrog Portland Thorns and leaders North Carolina Courage into pole position with three points, before those two face off on Monday morning.

Pride and Dash face off in must-win affair

It is approaching last chance saloon time for Orlando Pride and Houston Dash, who sit eighth and seventh respectively on the ladder ahead of their 9:30am Sunday morning meeting. 

Alanna Kennedy and Emily van Egmond's Pride have hit their best form of the season in the last month, winning three of their last five matches - but unless Orlando can take maximum points from Houston, the Pride's slim hopes of making the Final series will be all but over.

While the situation is not as desperate, it is still a similar story for Clare Polkinghorne and Kyah Simon of Houston, with the Westfield Matildas duo seven points off fourth spot but having played two more games than Orlando. The loser in Sunday's meeting at Exploria Stadium might very well have to concede their campaign is over. 

Top two clash in Portland

It is looming as one of the games of the NWSL season as Portland Thorns host North Carolina Courage on Monday morning, kick off 5:00am AEST. 

Portland - who have Hayley Raso, Ellie Carpenter and Caitlin Foord on board - missed the chance to regain the lead after falling 1-0 to Reign FC on Thursday.

The Thorns will be desperate to bounce back from that loss and a 1-1 draw with bottom club Sky Blue last weekend, but know they'll have to muster a much-improved performance against a Courage team beginning to hit their stride ahead of the run home.

Reign FC aiming to continue momentum

After beating Portland 1-0 on Thursday, Reign FC are firmly back in business.

Steph Catley and Lydia Williams' side are just two points off top spot ahead of their home clash with Utay Royals on Monday morning, 9:30am kick off.

Should North Carolina and Portland draw in the early fixture, Reign FC could potentially move level on points, but it won't be easy against an Utah Royals side who boast a water-tight defence.
