IT may not have been his biggest performance, but Andrew Walker's impact in Round 7, 2011 will go down as one of his most memorable.

And with Carlton to take on St Kilda in Sir Doug Nicholls Round, it’s only fitting to look back on the performance of the man who would ultimately become the first Indigenous player to reach 200 games.

It was a career-best season for Walker back in 2011, where a shift to the forward line gave him a new lease on life.

As someone who burst onto the scene with one of the most famous Carlton debuts, Walker’s 2011 was well and truly the one where he announced himself.

Ending the year as the Club’s leading goalkicker, it was also the year where he took the unofficial Mark of the Year.

But against the Saints in Round 7, he proved to be the hero on a Monday night in May.

Carlton led by as much as 28 points against the Saints, before the team which played in consecutive Grand Finals in the years prior roped the Blues in.

Come the final quarter, the Saints led by three points, and Carlton need a spark.

Enter '1AW'.

Taking a typically strong mark overhead, Walker displayed nerves of steel to go back and slot the goal with just minutes remaining to give Carlton the lead.

Not long after, the siren sounded, and the Blues were victors in Jordan Russell’s 100th game.

While Walker’s final stats weren’t particularly noteworthy — nine disposals and two goals — it was a match remembered for a classic moment.
