After a solid first half, they took the lead in the 49th minute, with a well executed Daewook Kim header from a free kick. The goal shocked the Antlers, who brought on their two top strikers soon afterwards.
The end result was fair on the balance of play, as Kashima created the best opportunities, especially in the final 25 minutes. But Auckland City will also ponder what might have been, in a game of such fine margins. Both goals they conceded were comparatively poor by their standards, with the defence guilty of ball watching for the first and hesitation for the second.
But the Sandringham-based club will take pride from their display. They pushed Kashima to the limit, and started to frustrate the Japanese champions in the second half, as they held the lead for almost 20 minutes. One of the high points was just before the hour mark, when Auckland City were ahead on the scoreboard and knitted together several intricate triangles in possession, as they grew in confidence and the game began to open up.
The best summary of their performance came from veteran Fifa commentator John Helm, as he pondered an improbable upset midway through the second half.
"One thing about Auckland - they will be calm," said Helm. "They play as a unit. Everybody defends, and everybody attacks when they can."
