THE BRISBANE Lions have backed up last week's breakthrough win over Carlton with a stunning 37-point victory over Port Adelaide.

After a low-scoring start to the game, the Lions booted six goals in the second term to set up the impressive 15.12 (102) to 8.17 (65) triumph.

The win sees the Lions move off the bottom of the ladder, while questions will be asked of Port Adelaide's premiership aspirations after they slumped to their fourth loss of the season.

Dayne Beams (32 disposals and one goal) and Daniel Rich (23 and nine clearances) led the way for the Lions, who were assisted by Port's wastefulness in front of goal.

Travis Boak (27) and Robbie Gray (25 and one goal) toiled hard for the Power, while veteran Kane Cornes had 13 disposals and kicked one goal in his penultimate match before retirement.

Lions coach Justin Leppitsch said it was the best win of his short tenure at the club.

"We didn't win all the KPIs on the day, but if you play your role, you always give yourself a good chance to win," Leppitsch said.

"I always felt he players bought in to what we were doing. It was just the execution (that had been the problem).

"We've got a bit of confidence in the execution now and that's what last week did and this week reinforces again."

Leading by 21 points at the main break, the Lions extended their advantage four minutes into the second half when Jed Adcock booted a great goal from beyond the 50.

Two majors to Angus Monfries had Port back in the contest until Brisbane kicked three of the next four goals to lead by 25 points at three-quarter time.

The visitors had two golden opportunities to narrow the deficit through Monfries and Paddy Ryder in the early stages of the final quarter but were punished for their profligacy when ex-Blue Mitch Robinson kicked his third goal, three minutes into the term.

Chad Wingard rekindled Port's hopes when he booted his first major of the match after three prior misses, however goals to Rich, Ryan Lester and Lewis Taylor took the Lions' advantage beyond seven goals inside the final 10 minutes.
