In the end, it wasn't even close. A 47-run defeat in a Twenty20 is an absolutely shellacking. 79 is India's second-lowest total in T20 cricket. The nine wickets by New Zealand's spinner's equals the T20 record.

"You could not have predicted this. India came out with the ball on fire, but with the bat they have completely given this away. Well done to New Zealand, it's been a brilliant fightback, and their spinners really did the job."
Nehra b Milne 0 (Ind 79 all out)
Bowled him! Adam Milne splatters Ashish Nehra's stumps and India wrap-up a 47-run win. India, the hosts and favourites, have been humbled in the opening match of this tournament. Let the post-mortem begin.
Jasprit Bumrah joins Ashish Nehra. India are set to join England as the only hosts to lose their first match in a World T20...

"What a catch! That ball was dying on him. It just shows you how fired up this New Zealand team have been today. The crowd are starting to file out now..."
Dhoni c McCullum b Santner 30 (Ind 79-9)
What a catch! A brilliant, tumbling take by Nathan McCullum at long-on removes MS Dhoni and ends this match as a contest. Dhoni looked to hit Mitchell Santner downtown, but McCullum came off the fence to dive forward and cling on. The fans are leaving the ground. Tell the Fat Lady we'll need her soon.
Pull for four by Dhoni, the first boundary conceded by Santner. The skipper still believes.

Amos Kemp: Just seen a poster "Invented by England, Mastered by India" Are they referring to The Batting Collapse?
Ashish Nehra is the new man - he's a place too high at number 10. The crowd know it too, cheering when he manages to keep his first ball out. Dhoni is even refusing the single that would see him lose the strike for the next over. India need 52 from three. No chance.

"Ashwin was doing such a good job keeping Dhoni alive while picking up a few singles. He just got done by the spin there. He was tempted into playing and found himself falling over. Very difficult for India now. Dhoni is the only man with any sort of hope."
Ashwin st Ronchi b Sodhi 10 (In 73-8)
Gone! Beautiful from Ish Sodhi, a perfect leg-break completely befuddling Ravi Ashwin, who walks past it to be smartly stumped by Luke Ronchi. New Zealand are properly into the tail now. MS Dhoni is standing on deck as his ship goes down.

"If you are going to go down, go down fighting. MS Dhoni got right to the pitch of the ball and hit it gun-barrel straight. Straight has been the key."
Fetch it! Here comes Dhoni, six down the ground off Sodhi.

Phillip Huntsman: Without wanting to ruin this... MS Dhoni is still there. If this game has taught us anything it's don't write people off.
Some fans in Nagpur can't even watch, with Corey Anderson back on to prolong India's boundary hunt. Still it won't come, still Dhoni has to settle for singles, still the rate continues to climb. It's like someone has turned the volume down in Nagpur. There are four overs to go, three of which no doubt to be bowled by the spinners.

"Even on a good pitch, on a good day, 66 runs to win from 30 balls would see the advantage with the bowling side. And on this pitch, despite MS Dhoni being the crease... it's going to be very tough for India. New Zealand won't want to settle in though, I think they'll really want to make a statement."
Now Dhoni looks for the big one, but a mishit off Sodhi only brings a couple. The skipper is right to think the burners are needed soon - that rate could get unmanageable. However, the boundary still hasn't come and there are only three wickets left in the bank. India need 66 from five. A huge ask.

"Virat Kohli batted well but other than that some of the shots India have played have been lacklustre. It's almost as if they expected this to happen."
Mitchell Santner is all over the place here, sprinting to field off his own bowling. Mixing the pace, turning the ball, keeping a mesmeric hold over these Indian batsmen. What do Dhoni and Ashwin do? At the moment, it looks like the plan is to hang in there until a blast at the end. Problem is, the required rate will be 12 before much longer.
