It was expected as Dhoni was just wasting the balls and not trying to score , even he was weak in running between the wicket. And in the end West Indies won this low score thriller match.
May be Dhoni was really tired in this match and so was the reason he was not striking the ball really well,he wasted a lot of balls ,may be the pitch is not suitable for batting,but either way India could have won the match but ,it was a stellar performance from West Indies despite defending a low score.
Dhoni will be blamed for this defeat, but he did score 50+ runs. In a low scoring match, this could have been crucial in achieving the target. Unfortunately, India couldn't finish the match and Dhoni gets the blame.
It was an easy match if anyone of the other end batsmans stayed without giving a gift wickets to West Indies bowlers. Dhoni should have played more attacking and out looked like they don't care about a loss. The series could have been a whitewash.
