Marinoff stars as Adelaide down Port in AFLW

Adelaide's co-captain, renowned as among the competition's premier players, propelled her side inside the attacking 50m zone eight times, won five clearances and laid 10 tackles.

Adelaide's Jessica Allan booted two goals and ruled the rucks with 30 hitouts while teammates Anne Hatchard (22 disposals, 12 tackles, one goal) and Madison Newman (19 possessions) were also standouts.

Port's 50-gamer Ashleigh Saint (15 touches, one goal), Abbey Dowrick (14 touches, one goal), Sachi Syme (18 disposals) and Shineah Goody (one goal, 15 possessions) all battled gamely.

But Crows star Marinoff was unable to be controlled - the five-time All Australian set the tone for Adelaide with a commanding first quarter.

Marinoff gathered eight disposals featuring three inside 50s to help her side create a 12-point advantage at quarter time, 3.1 to 1.1.

After Adelaide's Brooke Tonon slotted the first goal, her dangerous attacking teammates Eloise Jones and Hatchard also scored while Port's Julia Teakle converted a 35m set shot for the home side.

The Power closed the gap in the second term with majors to Shineah Goody and Gemma Houghton, punctuated by a goal from Adelaide's Allan from a ruck infringement.

The Crows held an eight-point buffer at halftime, 4.4 to 3.2, and stretched their lead to 15 points early in the third quarter when Chelsea Biddell marked and goaled.

But the Power struck against the tide when Dowrick sprinted into an an open goal from a rare attacking foray.

The Crows, despite having 20 more inside 50s than Port at three-quarter time, led by only 10 points, 5.7 to 4.3.

Ruck Allan's second goal gave the Crows a 16-point break just two minutes into final term and settled the result before a crowd of 5194 spectators.
