It took breaking a formidable Brighton Districts reign to win it in the Victorian Women's Cricket Association premier seconds final.

Naps-Sebas eclipsed Brighton's 97 runs with seven wickets down and six balls spare.

Brighton had been vying for a third consecutive title - Naps-Sebas had been its runner-up the past two summers.

Naps-Sebas captain-coach Sara Cavanagh said the match went right down to the wire and she was thrilled her team could polish it off.

"The girls are extremely excited. It's very good, very unexpected to win," Cavanagh said.

"Our goal was to win the toss and elect to bowl first because we seem to perform better when we're set a target."

Naps-Sebas all-rounder Beth Taylor was player of the match.

Taylor composed 46 runs with solid, sensible batting and a couple of big sixes to keep Naps-Sebas in the game.

Cavanagh said the odd boundary through the innings kept Naps-Sebas in touch with Brighton in what was very much an ebb-and-flow sort of game.

Naps-Sebas dropped handy catches early but managed to restrict Brighton to a modest 97 runs.

In the chase, the required run rate became six runs an over with 12 overs to go and it was the "odd boundary" that made play stay tight.

Sixteen-year-old young guns Jacinta Goodger and Emma Lynch impressed in their final debut with Naps-Sebas.

Cavanagh said both proved "real live-wires" in the field, running hard to stop the ball and keeping energy high in the playing group.

Naps-Sebas topped the VWCA premier seconds' Twenty20 ladder, winning nine of 10 matches to claim its final spot.

The team must quickly move back to business.

Naps-Sebas, the only regional team in the Melbourne-based premier seconds, is vying for a fourth-consecutive one-day premiership.

It sits second in overall stakes with one round to play, next week, before hosting a semi-final at Napoleons.
