It was ultimately a tough result for the Hawks at the MCG; they had their opportunities but despite a gallant effort, were unable to turn them into the all-important four points when the final siren sounded.

Hawthorn had the chance to storm into the lead late in the third quarter when young key forward Jacob Koschitzke marked on the goal line, only to play on and be tackled by the onrushing Nic Newman.

It proved a decisive moment in the game, with Carlton heading directly up the other end and converting through Michael Gibbons before kicking the next three goals to end the third term.

Speaking afterwards, Hawks coach Alastair Clarkson said the 20-year-old's brain-fade was indicative of a young side that is going to make mistakes as it fights through a challenging rebuilding phase.

"It was probably a little bit impulsive and that was us for the day," Clarkson said.

"We probably played on from marks quicker than we needed to throughout the course of the game. We put ourselves under pressure with the live ball. That was the difference in the game.

"Carlton had the composure they needed to make good decisions and execute and we chose often to put speed on the ball. Speed on the ball is a good thing if you've got composure. It isn't great if you're in a rush.

"His blue right on the goal line was just a reflection of young players playing on impulse, getting going and being excited about the game. That was tough, but we live and learn and get on with it."

Despite the hiccup, Koschitzke was one of several young Hawks who showed promise in the outing, accompanied by the likes of Harry Morrison (two goals), Jack Scrimshaw (nine intercept possessions), James Cousins (six inside 50s) and debutant Ned Reeves (21 hit outs).
