Sydney: Steve Smith completed his fourth century in as many matches on Wednesday as Australia continued to build a massive first innings total in the final test against India.
Smith joined South Africa`s Jacques Kallis as the only batsmen to score hundreds in every match of a four-test series with a composed 117 as Australia cruised to 420 for four at lunch on day two at the Sydney Cricket Ground.
Australia also lost Shane Watson for 81 in the morning session, caught by Ravichandran Ashwin at deep midwicket off the bowling of Mohammed Shami, leaving Shaun Marsh unbeaten on 14 and Joe Burns yet to score to carry on after lunch.
Watson and Smith added 196 for the third wicket after openers David Warner (101) and Chris Rogers (95) put on an even 200 on the first day as Australia`s top order cashed in on a flat pitch perfect for batting.
Smith continued his extraordinary run of form, following up his 162 not out in the first test in Adelaide, 133 in the second test in Brisbane and 192 in the third test in Melbourne with another hundred.
Only Kallis, who made hundreds in all four tests against the West Indies in 2003-04, had achieved the same feat.
Smith, who replaced the injured Michael Clarke as captain for the second test, also set a new record of his own, becoming the first batsmen to score hundreds in his first three tests as skipper.
Resuming on 82, he reached his eighth test ton off 168 balls when he smashed a full toss from Indian fast bowler Umesh Yadav for a boundary.
Yadav gained a small measure if revenge when he dismissed Smith just before the interval, finding the edge off an attempted drive and giving wicketkeeper Wriddhiman Saha a simple catch behind the stumps.
Watson, batting cautiously after a lean run in the three previous tests, looked set to register just his fifth test hundred since making his test debut a decade ago, only to throw his wicket away with a rash shot.
His dismissal marked the 24th time Watson had made a test half-century but failed to go on and reach triple figures.
