Former South African captain Shaun Pollock slammed the technique of the Indian batters in their capitulation on Day 5 of the second Test in Guwahati. The hosts entered the final day with their back against the wall at 27/2 in a run-chase of 549.However, they offered no resistance to be bowled out for an embarrassing 140 halfway through the day, suffering a 408-run defeat. It was India's biggest defeat by runs in Test cricket.Talking about the hosts' final day collapse on Cricbuzz, Pollock said (3:40):"Technically there were a few issues today. Some of the players not picking length, lunging forward and getting themselves into trouble. Sai Sudharsan went nowhere, which didn't help his innings. India also let South Africa off the hook from 247/6 after Day 1. And then losing six quick wickets in their batting innings, you can't have those in Test cricket and expect to be competitive. I felt like they were always going to lose today but just wanted them to fight and try and take it as deep as possible."He continued:"But sometimes it's these losses that act as a catalyst and there is a rethink, rejig, restructuring and the team can go from strength to strength after that. But apart from Gill, Jaiswal and Rahul, the others making up the top six is where the concern lies."The massive defeat in the Guwahati Test meant India lost the two-match series 2-0. It was their second home Test series whitewash in just over a year after New Zealand defeated them 3-0 last year."Manner in which the defeat happened today was more concerning" - Shaun PollockShaun Pollock believes the manner of India's defeat to South Africa in the second Test was more shocking than the result itself. The hosts lost the series opener in a low-scoring thriller in Kolkata by 30 runs.However, with a win required to avoid a series defeat, the home side were uncompetitive throughout the five days, suffering their worst-ever loss in the red-ball format."The manner in which the defeat happened today was more concerning. I expected them to grind out a reply. But to be bowled out for 140 was disappointing. It's left them with a lot of thinking to do. 0-3 and 0-2 was not something anyone would have predicted 18 months before. It was always a case of you rock up in India and you're going to get beaten by the spinners," said Pollock (via the aforementioned source).He added:"Yes, Gill not batting in the two games made a big difference. The first game in Kolkata was close and if that went the other way, maybe there's not so much of a concern. But to lose that and the fashion of defeat in this one is the one that's going to hurt the most."It was India's third Test series defeat in their last five affairs, including a second at home in their previous three.
