Sydney, Jan 5 : Michael Clarke has become just the seventh Australian to score a triple century, stepping into rarefied company during his marathon innings of 329 not out against India in the second Test at the SCG.

By flicking fast bowler Ishant Sharma through mid-wicket to the boundary Clarke joined one of cricket's most exclusive clubs.

The enormity of the achievement was not lost on him as he dropped his bat, raising his helmet in one hand pumping his free fist high in the air.

Batting into a third consecutive day, Clarke was the first Australian to achieve the feat since Matthew Hayden's Australian record score of 380 in Perth during 2007, The Herald Sun reports.

And he was the first Australian captain to score 300 since Mark Taylor in Pakistan 14 years ago.

Clarke is just the seventh captain in Test history to achieve the milestone and the third Australian skipper behind Taylor and Bob Simpson, who made 311 against England at Old Trafford in 1964.

Even before Clarke achieved those imposing feats he created another record on his home ground.

By smashing a short ball from Sharma through cover point to the boundary, Clarke claimed the highest score at the SCG, beating the 287 by England's Reginald `Tip' Foster 109 years ago.

The previous highest score by an Australian at the ground was 242 by Doug Walters in 1969. (ANI)
