Around 30k spectators in the stadium but the stands are still looking empty for obvious reasons. It doesn't look like an opening match of the ODI WC, having said that 30k audience for non-indian match in India is not bad, in most stadiums it's a full house. Still, ICC should've opted for a different stadium.
Coming to the match, I didn't feel the urge to watch the match but it seems spin played a big role in the first inning. Poms do look short here and Kiwis are marching nicely but in the middle overs Moeen-Rashid duo can slow the game, hope it goes to the wire.
The seating arrangement is more than 130k which is why the stadium seems empty. I am watching the match on Hotstar and I can see 44L showing up now. People are crazy about T20 cricket only a few like you and I are the ones who watch ODI. Watching the way spinners are getting whacked for 4 and 6, I do not agree with your analysis. It is all about captaincy and discipline when it comes to bowling. Might as well say, what a fantastic debut by Ravindra.
