PORT Adelaide remains a game clear in the top eight after edging out the Brisbane Lions by nine points at AAMI Stadium on Sunday.
The Power dominated general play and forward 50 entries but inaccuracy in front of goal left them scrapping for the 9.17 (71) to 9.8 (62) win.
Forward Jay Schulz kicked two goals in Port's precious win before 22,631 spectators.
Power captain Travis Boak (27 disposals) and Hamish Hartlett (26 touches) were influential in a victory which all but kills off the Lions' chances of making the finals.
The Lions are now three wins outside the top eight with five games remaining, but were brave in defeat.
The Lions were inspired by dynamic midfield duo Jack Redden and Tom Rockliff, who collected a game-high 28 possessions, while Dayne Zorko and captain Jonathan Brown booted two goals each.
But the Lions were unable to claw their way back from a four-point deficit at three quarter-time.
Port's Chad Wingard ended a remarkable stalemate in the last term - kicking a goal after nearly 16 scoreless minutes to give the Power breathing space.
Port held sway early and led by 3.4 to 1.4 when Justin Westhoff kicked a goal after the quarter-time siren.
But the Lions' prolific ball-winner Daniel Rich led a rapid response, providing three goal assists as the Lions took a three-point lead 15 minutes into the second term.
Port then launched a challenge of its own as impressive youngster Ollie Wines and John Butcher scored majors within two minutes of each other for the Power to lead 5.9 to 4.5 at half-time.
The Lions, with Zorko scoring twice, booted five goals to three to creep within four points at the last change.
But despite kicking with a stiff breeze in the final term, the Lions were held goalless - registering just two points as Port relentlessly defended until Wingard's goal broke the deadlock.
Port meet home-town rivals Adelaide next Sunday while the Lions host St Kilda on Saturday night.
