The Netherlands found themselves forced to dig deep in a thrilling opening match against New Zealand to start the days action, while Chiles goalkeeper Christiane Endlers heroics were unable to stop Sweden from winning their first match at the World Cup.
New Zealand 0-1 Netherlands
The Netherlands left it late against New Zealand to kick start their World Cup campaign with a win, but Jill Roords late header ensured that Sarina Wiegmans side joined Canada at the top of Group E.
Despite being in control for most of the match, New Zealands tactics saw them presented with a handful of opportunities on the counter-attack, but it was actually a defensive mistake from the Oranje which saw Olivia Chance come close to breaking the deadlock, only being denied by the underside of the crossbar.
Rosie White and Sarah Gregorius forced goalkeeper Sari van Veenendaal into smart saves either side of half-time, but for all their chances New Zealand werent able to put the ball into the back of the net.
WSL top scorer Vivianne Miedema came close to scoring her first of the competition at the other end of the pitch, sending one effort narrowly wide of the post before Erin Nayler was forced into a smart save at her near post.
But in the 92nd minute, Merel van Dongens deep cross was headed back across goal by Lineth Beerensteyn for fellow substitute Roord to nod home the winning goal, leaving New Zealand empty-handed despite their impressive display.
Chile 0-2 Sweden
It looked for all the world that Chiles match against Sweden would be heading for just the second draw of the Womens World Cup so far,
Sweden were in control of the opening 45 minutes and were just inches away from taking the lead when a deflected header was on course to creep into the corner of the net, but Chiles star performer Christiane Endler somehow got a hand to the ball and cleared the danger.
Just before the 72nd minute, the referee halted play due to adverse weather conditions and there was a lengthy delay in proceedings, but the pattern of the match continued after the game resumed as Sweden continued to press for the opener.
Just 10 minutes before full-time, Sweden finally found a way past Endler when Kosovare Asllani pounced on a loose ball inside the penalty area before firing a stunning left-footed effort into the top corner or the net.
Sofia Jakobsson couldnt put the game to bed and saw a dinked effort sail over the crossbar, but Sweden were able to put the icing on the cake when substitute Madelen Janogy went on an impressive solo run before rounding off the scoring in Brittany.
USMNT 13-0 Thailand
The United States Womens National Team (USWNT) kicked off their title defence with a breathtaking 13-0 win over Thailand at the Parc des Princes, the biggest ever win in Womens World Cup history.
Alex Morgan had the ball in the back of the net inside the opening six minutes but her header was correctly ruled out by VAR for offside.
Unfortunately for Thailand, that decision was arguably their best moment of the match and they inevitably did concede the first goal of the game just a few minutes later, with Morgan this time timing her run to perfection before nodding the ball into the back of the net.
Morgan then turned provider to set up Rose Lavelle, whose 25-yard effort caught goalkeeper Sukanya Chor Charoenying off guard at her near post to double the USWNTs lead.
Two stonewall penalty appeals were waved away by both the referee and VAR, but Ellis side were able to add a third before half-time when Lindsey Horan was presented with a tap-in from just a few yards out.
Shortly after the restart, Sam Mewis deflected effort from the edge of the box extended the USWNTs lead even further, while Morgan was once again in the right place at the right time to add a fifth.
Five became six just seconds later and this time it was Mewis who scored her brace, while Lavelle also picked up her second of the match before the hour mark.
Thailand were able to hold out for a little while longer, but they were helpless to stop Morgan from completing her hat-trick, with a clever piece of skill on the edge of the area creating space to unleash a shot into the far corner.
USWNT veteran Megan Rapinoe rounded off a counter-attack to add their ninth of the match, while Morgan took her side to double figures with her fourth and fifth goal of the game, either side of Mallory Pughs effort in the dying stages of the match.
Perhaps their most important goal and the biggest cheers was saved for added time, however, as American icon Carli Lloyd rounded off the scoring with a cool finish after coming off the bench earlier in the second half.
