Steve Smith among the greats after another run feast

AT just 25, Australia's acting captain Steve Smith has joined legendary company.

His 117 on day two of the fourth Test at the SCG saw him become just the third cricketer - behind greats Sir Donald Bradman and Jacques Kallis - to score tons in four consecutive Tests in the same series.

Smith's heroics allowed him to declare at 7-572, with India 1-71 at stumps.

The milestones didn't stop there for the young skipper.

Smith became the first man to score centuries in the first innings of his first three Tests as captain, and he is now the only man, alongside Kallis, to score hundreds in all four Tests of a four-Test series.

The New South Welshman has the Bradmanesque figures of 698 runs from seven innings at a staggering average of 139.60 in this series.

From just nine deliveries though, tail-ender Ryan Harris threatened to steal his skipper's thunder.

The veteran quick came to the crease with a declaration looming and blasted 25 from just nine balls.

Harris hit five fours, including a boundary off the first ball he faced from Bhuvneshwar Kumar, who was well under his usual pace.

Wicketkeeper-batsman Brad Haddin went one better, smashing Mohammed Shami for six down the ground off the first ball he faced.

India's lacklustre bowling offered temporary relief to under-fire Australian batsmen Shane Watson (81) and Joe Burns (58).

Watson was well and truly in the spotlight going into this innings after making just one half-century in 2014, while Burns managed just 13 and nine on debut in the Boxing Day Test.

Watson will still cop criticism for being unable to convert 50s into 100s. Yesterday was his 24th half-century, and he has made just four Test centuries.

While he took 183 deliveries to reach 81, the innings could be enough to see the 33-year-old all-rounder hold onto his spot for the two-Test series in the West Indies, starting in June.

Shaun Marsh would also be rueing another missed opportunity.

After running himself out for 99 in Melbourne, he made 73 yesterday, edging one behind off Shami after showing little footwork.

Shami was the pick of a disappointing Indian attack, finishing with 5-112.

The tourists will fancy their chances of making a decent fist of the run chase today with Rohit Sharma unbeaten on 40 and Lokesh Rahul not out 31.

Captain Virat Kohli and in-form Ajinkya Rahane are the next men in.
