Goals from Nikita Whinnett and Bianca Baptiste secured a 2-0 victory over Coventry United at Cheshunt FC.
The result stretched table-topping Spurs' lead to eight points over Coventry.
Spurs are currently four points clear of second-placed Charlton - who have played three games more - and six clear of Cardiff, who have played the same 14 matches.
It was the perfect preparation for their first cup final of three this week when they face Charlton in the Boux Avenue (Ryman) Cup Final at Cheshunt FC on Wednesday night.
