(ESPNCRICINFO) – NEW Zealand took massive strides towards doing the unthinkable: not just their first Test series win in India, but also India’s first series defeat at home in 12 years. Mitchell Santner, who had never taken four wickets in an innings before this Test, and with just one first-class five-for to his name, tied India to the crease and took seven wickets to bowl India out for 156. The batters, led by Tom Latham, did some efficient front-running by attacking the Indian spinners to end the day with a lead of 301 runs with five wickets in hand.

India have only twice overturned a lead of 100 to win a Test: the great Kolkata Test in 2000-01, and a successful chase of over 400 in Port-of-Spain in 1976, for long the highest in Test cricket. They found themselves in this situation because their legendary spinners were outbowled by two who came into the match with two first-class five-fors between them. Glenn Phillips was Santner’s partner in crime, taking out the two dangerous left-hand batters, Yashasvi Jaiswal and Rishabh Pant.

Santner bowled unchanged through the day for 17.3 overs. Six of his victims were either bowled or lbw as he kept attacking the stumps with balls behaving differently from the same spot. This wasn’t quite the square turner that India lost their last Pune Test on – against Australia in 2016-17 – but there was enough turn and enough variation in turn to not allow India the ultra-aggressive approach they have employed this home season.
Right from the first three balls of the day, the challenge for India was apparent. From the same spot, the first one turned lesser than expected, the second one went straight on but Shubman Gill survived the umpire’s call, and the third one turned big past the outside edge. There was not just turn, but also quick turn and natural variations from the surface.

India had batting till No. 9, but on such pitches, the depth doesn’t mean much. So accurate was Santner that it took just 47 false shots to run through India. For the first half hour, though, New Zealand’s patience and belief was tested. Gill managed to start breaking free with a six off Tim Southee after charging at him. Yashasvi Jaiswal drove Southee for a four, before Ajaz Patel, the lead spinner on paper, offered him another half volley.

But it turned around for New Zealand in the 22nd over of the day when Santner again beat Gill with one that went straight on. This time the umpire’s call went the bowler’s way. As the 15 seconds on the DRS timer lapsed, the crowd broke into a big cheer. For the arrival of Virat Kohli. The joy for them was short-lived as Kohli soon missed a full toss, which he tried to mow to square leg. The ball did drift in from the initial line, but it was still a full toss that Kohli would have dispatched almost every time had he played with a straighter bat.

By now, the effect of the roller was wearing off. Batters were shanking even full balls – or those that they got close to – by using their feet. The ones that didn’t turn created further doubt. As it tends to happen at such times, fielders were everywhere: a hard sweep went straight into the shin of short leg, a short ball stopped and turned, and the pressure kept mounting.
