The Matildas striker has been in the league since it's inception in 2013, first with Western New York Flash and now with New Jersey-based Sky Blue.
Sky Blue were down 2-0 in the 78th minute when the 23-year-old grabbed her first of the match with a classy diving header.
Kerr then went on to equal the record in the 81st minute with a smart first-time finish into the bottom corner.
The Perth Glory forward then went on to win the game and take the record in the 90th minute. Kerr was slipped through on goal and with a deft first touch managed to hold off her marker before slotting the ball home to make it 3-2.
