Naps-Sebas lost a tight, gruelling battle to Coburg at Napoleons in the Victorian Women's Cricket Association premier seconds.

Coburg eclipsed Naps-Sebas' 117-run tally  with eight balls to play and two wickets in hand.

Naps-Sebas captain-coach Sara Cavanagh said it was a mentally taxing, but fantastic semi-final.

"It really was a good game, and awesome game to be a part of, despite the result," Cavanagh said.

"As captain, I really enjoyed the game. I had to really think and chop and change things about all the time."

Momentum swung dramatically through play with both teams' top orders ripped apart early.

Naps-Sebas was two wickets down with just two runs on the board and struggled to find momentum until youngster Emma Lynch stepped up to the crease.

Lynch took up the bat with Naps-Sebas at 4-23 and put on 31 runs, the bulk made in a in a 45-run stand with Karen Casey for the sixth wicket.

Fellow young gun Summer Dehnert help boost the Naps-Sebas tally with 16 runs in the lower order.

Naps-Sebas were back in the game when they pinned Coburg at 5-23.

Only they struggled to dislodge the 'Burgers' tail.

Cavanagh says it has been a great, successful for Naps-Sebas' women's team, with the club winning its first Twenty20 title a fortnight ago.
