It was then Ewington scored the first of his goals, pouncing on an error in the opposition defence, and after teammate Stephen Cole had made it 3-3, a cracking finish was in store.
There were anxious moments for Monkstown when a shot from a Rovers player hit Ewington on the body in front of his own goal and Rovers were awarded a stroke, a decision which was downgraded to a penalty corner after the umpires had consulted.
The penalty corner was fluffed and Monkstown lived to fight another day.
Then came a piece of Ewington magic.
With just four minutes remaining, Monkstown forced a penalty corner, the ball found Ewington's stick and his ripping drag flick bulldozed it into the back of the net, to the jubilation of teammates and supporters.
This wasn't the first time Ewington had starred in a Mills Cup final, having also scored twice when Monkstown beat Glenanne in 2011.
