With 2012 having been 'the year' for so many sportsmen and women across the world, it can be easy to overlook particular achievements across a range of sports.
However, when looking at cricket, 2012 has most definitely been Michael Clarke's year.
The Australian captain has continually bettered himself, and when he became the first player to hit four Test double centuries in a calendar year on Thursday, his place at the pinnacle of the sport was highlighted for all to witness.
With Don Bradman reaching three scores of 200 or more back in 1930 and Ricky Ponting achieving the same feat in 2003, Clarke's latest accomplishment expresses just how far he has come in the past year.
Having taken over the role of captain in 2011 from Ponting, on the back of the disappointing home Ashes defeat, the 31-year-old batsman has revealed truly outstanding form.
The New South Welshmen helped his Australian side dominate day one of the second Test against South Africa this week in Adelaide and it does not look as though anything will stop him on his quest now.
Having led his country to series victories against the West Indies, India and Sri Lanka, Clarke will continue to lead by example whilst also proving his worth as a reliable batsman.
Up to the current Test against South Africa, he had scored 1,041 runs at the average of 115.67 in just seven Tests this year.
With a record 329 not out in January at the SCG against India, Clarke's impressive form continued throughout the year.
He also hit 210 in the fourth Test at Adelaide before putting South Africa to the sword.
In the first Test against the Proteas in Brisbane last week, the skipper stole the show as he racked up 259 not out - while another mammoth score is now on the cards.
And the show is far from over though; with more Tests still to come this year, against South Africa and Sri Lanka, Clarke knows what he must do if he is to continue this remarkable form.
After being at the top of his game for the past year, it would be easy to become complacent yet, being the player and leader that he is, Clarke will not settle for adequate and will continue to strive for better, in both his team and himself.
