Dharamsala: Debutant left-arm wrist spinner Kuldeep Yadav bewitched Australia to take four wickets as Australia were all out for and even 300 late on the first day in the deciding Border-Gavaskar Test in Dharamsala on Sunday.
Australia skipper Steve Smith carried on his imperious form to notch his third ton of the Test series, but he was a vital wicket for India shortly before tea to depart for 111.
Opener David Warner notched 56, his first half-century of the series, and wicketkeeper Matthew Wade added a fifty of his own but that trio had little support, with the next top score the 21 from fast bowler Pat Cummins.
Kuldeep ran through Australia's top order in a bewitching 14-over second session spell, taking the key wickets of Warner, Peter Handscomb and Glenn Maxwell to put the visitors on the back foot.
The Australians had looked to be cruising with Smith and Warner notching twin fifties in the first session to guide the visitors to 1-131 at lunch on the first day. But with Kuldeep's intervention, Australia were restricted to 5-77 in the second session.
The break brought an immediate change in fortunes for India, with Warner the first victim for the 22-year-old. Warner was caught at first slip after getting into some bother against the bounce from Kuldeep, while Peter Handscomb was bowled through the gate having aimed a booming drive through the off-side against the spin.
Glenn Maxwell took the left-armer down the ground but was then undone by the googly, the ball clipping the off bail. Shaun Marsh also departed, tickling one down the leg side to be Umesh Yadav's second victim after the pacer had bowled Matthew Renshaw in the match's second over.
Smith had not set a foot wrong to bring up his 20th Test ton, becoming just the sixth man ever to score three Test tons in a Test series on Indian soil, and the first Australian to do so. But shortly before tea Ravi Ashwin found the outside edge of Smith's bat with the captain playing back to a full ball, and the chance was well held at slip by new captain Ajinkya Rahane.
India had a horror start - dropping Warner at third slip off the first ball of the match - to compound the loss of skipper Virat Kohli before the toss, and were made to pay as Australia raced out of the blocks at more than five an over.
Smith raced to his fifty to outpace a watchful Warner.
Then Smith called correctly at the coin toss, winning the right to have first use of the HPCA Stadium surface.
While Australia were unchanged, India made two changes from Ranchi – adding an extra bowler in uncapped left-arm wrist spinner Kuldeep Yadav for Kohli, and replacing pacer Ishant Sharma with Bhuvneshwar Kumar.
Australia - 300 (Smith 111, Made 57, Warner 56, Kuldeep 4-68)
India - 0 for 0
Status - India trail by 300 runs
