AFLW ScoreCentre: Carlton and Collingwood victorious in Saturday's AFLW clashes

Carlton has its AFLW season off and running after a hard-earned win against a gallant Geelong on Saturday.

The more-experienced Blues were pushed to the limit by the home side before winning by 14 points, 4.7 (31) to 2.5 (17) in a defence-dominated contest.

The second-round win provided Carlton midfield gun Maddy Prespakis with family bragging rights over younger sister Georgie, the Cats number 2 pick in last season's draft.

Both were valuable contributors to their teams, with Maddy raking up 29 possessions and Georgie working hard for her 15 disposals before being forced off under the blood rule after a knock to the face in the last quarter.

It was the first time two sisters have played against each other in an AFLW game.

The pair was involved in several midfield contests and Maddy gently chided Georgie over one of them.

«We both left Thursday morning to go to training and said good luck to each other. It's just the best,» said Maddy.

«She tried to sell me a bit of candy (baulk), but didn't finish with a goal, so she has to work on that a bit.»

Carlton captain Kerryn Harrington was brilliant with 23 possessions, marshalling the defence with able assistance from Gaby Pound to nullify Geelong's scoring opportunities.

Geelong skipper Meg McDonald held Blues sharpshooter and AFLW leading goalkicker Darcy Vescio scoreless, but the Blues found enough options to continually edge ahead in the dour battle.

Midfielder Brittany Bonnici stepped up in the absence of Collingwood's co-captains, turning in a dominant best-afield performance to haul the Magpies to a 27-point victory over St Kilda.

The Magpies are without Brianna Davey (ACL) for the season, while Steph Chiocci (Achilles tendon) was a late withdrawal but Collingwood still proved too
