Young pacer Bhuvneshwar Kumar made early inroads to help India reduce Australia to a precarious 83 for four at lunch on the first day of the second cricket Test in Hyderabad today. With suitable help from a strip that is offering variable bounce, the talented UP seamer rocked the Australian top-order with a triple-strike in his first spell removing openers David Warner for 6, Ed Cowan for 4 and Shane Watson for 23. Skipper Michael Clarke was batting on 20 with Matthew Wade for company at lunch. Earlier, Australia won the toss and elected to bat. India lead the four-match series One-Nil by winning the first Test played at Chennai by eight wickets.
