Port Adelaide has claimed a four-point win over Adelaide on Saturday night.
The 7.13 (55) to 7.9 (51) victory was Port's fourth in succession against the Crows and keeps them entrenched in the top four.
They trailed by 19 points at half-time and 10 at the final change but kicked three goals to one in the last quarter to win.
Adelaide played the final term with one less player on its bench after Brodie Smith and Will Hamill were concussed either side of three-quarter time, but it did not relent.
Aliir Aliir was magnificent for the victors, finishing with 21 disposals to go with five contested marks to take home the Showdown Medal.
Adelaide took control in the second quarter, kicking three unanswered goals, including two to Ned McHenry.
The second came from a brilliant piece of play from Darcy Fogarty – who had kicked his own goal earlier in the quarter – where he beat two Port opponents to win a contested ball and thumped it forward on the left boot to an unmarked McHenry streaming towards an open goal.
Rory Laird (31 disposals) continued his fine season, while youngster Harry Schoenberg continued to impress with more midfield time, finishing with a career-high 30 touches and six clearances.
