Australian allrounder Shane Watson struck twice and Spidercam earned the scorn of captain Steve Smith on day three of the fourth test with India 342-5 at stumps at the Sydney Cricket Ground yesterday.
Centuries from KL Rahul and Virat Kohli spearheaded the tourists' steadfast response to Australia's first-innings total of 572-7 (dec).
Watson was on a hat-trick in the final session, having trapped Ajinkya Rahane lbw and then finding the edge of Suresh Raina's bat.
Wriddhiman Saha safely defended the next delivery, but the scalps reinvigorated Australia's hopes of victory after a day dominated by Rahul and Kohli's 141-run partnership.
Kohli finished 140 not out, setting an Indian record for most runs in a test series against Australia.
