Northern Superchargers were then very good in the field with Alice Davidson-Richards, Linsey Smith and Georgia Wareham particularly impressive.
Here are Phoebe Litchfield's best shots.
The Aussie, who only joined Northern Superchargers as a late replacement for her compatriot Alyssa Healy, made 68 off 45 balls.
Ultimately it was the difference between the sides with Invincibles' top-scorer Cordelia Griffith making 30 not out.
Litchfield's best shots as she hits impressive 68
Match Hero Phoebe Litchfield: "To come away with the win is extra special and to do it at home is even better.
"Me and the skipper, we spoke about hitting the big pockets and running hard and then the boundaries came our way. It was a big partnership which we needed in the middle.
"I am not the biggest hitter. I can't really hit a six over mid-wicket so I have to try and work into the pockets and my aim is to move fielders round the pitch and score two and fours when I can.
"It is a massive difference, I think there were seven debutants in our first game. I think we've gelled really nicely."
Northern Superchargers stay third but they are now up to six points.
They are three clear of fifth-placed Invincibles.
Welsh Fire, Southern Brave and Superchargers are starting to pull away a little at the top.
The hosts win!

Almost another wicket as Mady Villiers drives down the ground and it drops just short of the fielder at long-on.
Invincibles need something very special from here.
Bates c Rodrigues b Cross 22 (Invincibles 82-5)
Game over?
Kate Cross returns and her first ball is pumped to the boundary by Suzie Bates but the England bowler immediately gets her revenge.
There's more width but Bates is only able to pick out Jemimah Rodrigues at point.
Bates goes for a miserable 22 off 28 balls.
Invincibles 78-4; need 66 more
And again!
Mady Villiers goes down the ground, and Kate Cross, running away from long-on, gets round but has to reach to take the catch.
It comes off the fingertips and runs into the boundary ropes.
Invincibles are just about hanging on.
