PORT Adelaide will look to keep the pressure on SANFL frontrunners Norwood and Woodville-West Torrens on Sunday when it hosts the Adelaide Crows at Alberton Oval in the fourth state league 'Showdown.'

The Magpies remain unbeaten by the Crows in SANFL matches between the two clubs since the first instalment of Port's newest local league rivalry in 2014.

Winning this year's previous encounter between the two clubs at Balaklava, Port Adelaide last year defeated the Crows twice - first at Clare and then in front of over 6,000 mainly Magpie supporters at Alberton Oval.

It's a crowd the club is hoping to achieve again as the club looks to firm a position inside the SANFL's top three.

Essential Power members are able to see the game three on presentation of their Essential Power membership card at the Russell Ebert or Bob McLean Gates at the Oval, with tickets costing just $14 for adults and $8 for concession.

Children under 18 are admitted free.

Action at Alberton starts at 2:10pm with a curtain raiser between Portland and Hope Valley's under-18s sides at 11:25am.
