Kerr sparked - and completed - a huge comeback for Sky Blue FC on Sunday, scoring a league-record four goals and missing a penalty as her side stole a 5-4 win over Seattle Reign.

No NWSL player had previously scored four goals in a match - Kerr scored her four goals in a half. She now has 15 goals for the season - three ahead of her nearest competition, Seattle's Meagan Rapinoe.

Kerr's excellent form is sending records tumbling this year. She became the league's all-time leading goalscorer in July, when her match-winning hat-trick over Kansas City took her to 34 career NWSL goals.

She was also a member of the Matildas side that notched an historic first win over the US, at the Tournament of Nations, in July.

Trailing 3-0 at half-time, Sky Blue looked set for defeat before Kerr hit her straps. Her first goal came just minutes into the second half, dribbling through traffic and over the line.

Her second goal, in the 68th minute, was more impressive. Kerr got on the end of a long ball inside her attacking half. One-on-one with a Seattle defender, and with another closing in, Kerr took the ball inside the area and fired on across goal into the bottom left corner of the net.

Kerr's hat-trick came in the 71st minute. It would be her second of the season - another league record.

She notched it in style, controlling a looping pass just past the halfway line amid four Seattle defenders. Taking off, Kerr slowed down on the edge of the area, and still surrounded by defenders, curled her shot into the top right corner.

With scores level at 3-3, the game wasn't done with yet. Seattle took the lead back in the 85th minute with Kiersten Dallstream scoring off a deflected save.

But Sky Blue equalised in stoppage time thanks to a header from Maya Hayes, before earning a penalty in the 93rd minute for a handball inside the area.

Kerr took the penalty but sent her shot into the crossbar, leaving scores tied at 4-4.

But the Aussie wasn't done with yet.

She latched on to a 94th minute corner kick, sent in by Taylor Lyttle, rising above four defenders, and sending a floating header past yet another defender and the Seattle keeper to steal the win.

Kerr's heroics sparked a wave of support and admiration on social media from teammates, opposition and the general public.

The win leaves Sky Blue just three points off fourth spot and a place in the playoffs.

Kerr was recently shortlisted for FIFA's Best Women's Player award. She is likely to be in action for the Matildas on home soil for friendlies against Brazil in Penrith and Newcastle in September.
