The pitch was the same. But the condition of the pitch changes due to the dew at night. This happened because BCCI had to organize the Day/Night match due to their broadcaster's request for more TRP.
Yeah. These greedy boards and broadcasters are usually the reason why the pitch conditions change drastically for two teams in the same match making it completely unfair for both of them.
You won't find such an issue in sports like Basketball, Baseball etc in comparison.
At least someone understood my point. It's true that broadcasters and the boards/event organizers want to make money from those tournaments, but it also changes the luck of the teams. The toss plays a big role in day/night matches. I feel like if India could have won the toss and elected to bowl first, they could have been the World Cup winner today.
All those are just excuses at this moment. Yeah, Dew cannot change the match conditions in Basketball, soccer and some more games because both team has to face the same condition at the same time.
