Launceston City avenged their early-season loss to Riverside by reversing the scoreline to win the Northern derby 2-1.
The largest crowd seen at Windsor Park since Olympic resumed statewide competition was treated to warm sunshine but a chilly reception from their neighbours.
As they had at Prospect a couple of months ago, Riverside took a 1-0 lead into the break but couldn't finish the job as City recorded their third win of the campaign to establish a six-point gap between the sides and leapfrog Kingborough on the ladder.
Olympic edged the first half, taking a deserved lead from the penalty spot as Aaron Campbell scored against his old team after Lachlan Clark upended Matt Spanos.
But City were a different proposition after the break, Pat Sullivan heading them level within a couple of minutes before Isaac Degetto struck first a post and then the winner, coolly steering home with 18 minutes to go after Jarrod Hill had done superbly to deny Noah Mies.
Roared on by a vocal home crowd, Olympic pushed for an equaliser but their hope was as misplaced as Luca Vigilante's last-minute chance.
After a first competitive hit-out in four weeks, City coach Lino Sciulli was delighted to be back in action, but politely declined to convey what he said to his players at half-time.
"Game of two halves," he said. "In the first half we looked like we had not played for four weeks whereas Riverside were sharp and wanted it more. We were poor and Riverside could count themselves unlucky not to get a couple more.
"At half-time I challenged them to get back in it, pleaded with them to try a bit harder and it worked."
His opposite number Alex Gaetani admitted it is becoming frustrating producing performances but not wins having still not collected a point at home.
"That's probably the first time this year that we've lost a game we should have won from being the dominant team," he said.
"The first half was excellent, the biggest problem was that we were only 1-0 up and that was dangerous.
"City are a tough opponent, taking nothing away from them. They're very competitive and really wanted to win."
Admitting it was getting hard to keep finding positives from defeats, Gaetani reserved praise for Jon O'Neill's job keeping the prolific Mies quiet.
"He wanted that role and is an excellent one-on-one defender."
Runaway leaders Devonport recorded an expected victory at lowly Kingborough but nearly blew a three-goal lead.
Eddie Bidwell and Ignacio Giampaoli had the Strikers two-up at the break and when Max Fitzgerald added a third five minutes later the points looked safe.
However, Horatio Gutierrez reduced the arrears and when Jack Turner added another it made for a nervous final three minutes for the reigning champions.
Glenorchy Knights just squeezed past Clarence, 10-0 on Friday night.
