In the end, no one remembers about such an innings. He even failed to get himself a century. According to the records, India managed to beat England by 7 runs. How they managed to do that is inconsequential. I would say that it was another close match, which England failed to finish properly.
Nonsense. Many people including me will always remember how Curran heroically played till the end for his country. This was his first ODI 50 and it would have been his first ODI 100 too though he sadly fell short.
Dismissing his effort and calling India's close win inconsequential is pure stupidity. This is a rare occasion where a bowler almost won the decider for his country which is why it will always be remembered.
Statistically, the margin of victory doesn't matter. Whether you lose by 80 runs or 8 runs, it's the same outcome. Eventually Indian bowlers held their nerve during the last three overs and managed to win the match (and thereby the series). What is the point in putting up such a tough fight, if he can't finish it? The 9th wicket partnership between Mark Wood and Sam Curran was worth 60 runs. If they had scored another 20 runs, then England could have won the match. Also, let's not forget the fact that Mark Wood was run out, after Sam Curran slipped and fell down in his attempt to return to strike.
