AUSTRALIAN pace workhorse Peter Siddle has provided an early breakthrough to take the fight to India in the second Test. At lunch on day two, India have crawled to 1-54, batting with caution in reply to Australia's first-innings 9-237 (dec) at Rajiv Gandhi Stadium. Opener Murali Vijay (29 from 106 balls) and classy No.3 Cheteshwar Pujara (15 from 55) are the not-out batsmen. Starting the morning on 0-5, India suffered an early blow when struggling opener Virender Sehwag (6) edged behind a Siddle delivery pitched on a perfect length to leave the hosts 1-17. It was due reward for Siddle, who bowled with vigour in the first Test, and the ideal start for the tourists after skipper Michael Clarke's outstanding 91 provided the backbone of Australia's innings. Inspired by MS Dhoni's 224 in Chennai, the Indian batting order were almost cavalier in their approach in the first Test but today they resembled corpses with pads on. By lunch, their run-rate had slowed to 1.80 per over with the Indians adding just 49 runs in 30 overs in the morning session. Underlining the snail-like pace, when Vijay thumped Xavier Doherty to the long-off boundary, it represented India's first four in 82 minutes and 110 balls. But the Australians deserve credit for keeping a lid on the top order, bowling tight lines and with patience in a bid to lure Vijay and Pujara into a loose stroke. Siddle finished the first session with 1-20 from eight overs, while James Pattinson (0-16 from 10 overs) and Moises Henriques (0-3 from seven) were also economical. The underfire Doherty, who has three Test scalps at 102, was brought into the attack 30 minutes before lunch. Under pressure to perform after the axing of Nathan Lyon, Doherty started nervously but settled quickly to concede 12 runs from his first five overs.
