The midfielder kept her nerve to slot home from the penalty spot in the last minute to secure a 2-1 win and further strengthen the team's sixth place in their first season in WSL 2. Katie O'Leary was also on target.
They will now try to chase down London Bees, who are two points ahead in fifth having played a game more.
Spurs return to WSL 2 action and a game against Sheffield FC at Cheshunt FC on Sunday (2pm).
