The Swans made a typically flashy move through the corridor before going wide to Warner.
He kicked long to Hayden McLean who copped an “ear massage” from the Saints defence but held onto the mark.
He went back and kicked the goal.
The Swans were within a point but the Saints took the ball into their forward line and Bradley Hill snapped a low, grubber kick that bounced into the goals.
“How did he beat the goalkeeper?” joked Brad Johnson on Kayo Sports.
Saints 94, Swans 87 with 14 mins to play.
