This might not be true regarding the other two formats of the game where Bangladesh winning over West Indies makes headlines. But, in a T20 game that happens to be just a formality with both teams having an equal chance of winning or losing the match. Likewise, even in a one day international, it would not be anything new in case West Indies lose to Bangladesh despite the likes of Chris Gayle and Ramnaresh Sarwan having their presence in the team. Let alone Bangladesh, even had Ireland been in place, they would have chased down that total of 133 set by West Indies.
It might turn out to be a Romantic's Blog in case I write something favoring one particular team in games which can go anybody's side. The main culprit of the game would be the West Indian batsmen who could not pile up more than 132 runs on the board. I just condemn the WICB for not including Gayle, Sarwan, Chandrapaul etc in the playing XI for reasons best known to WICB alone. If that was one side of the coin, the other side also points fingers towards the batsmen like Barath, Bravo, Marlon Samuels etc who could have got the job done to their team.
You can take a look at the scorecard to see the bowling chart of the Bangladesh team which had just 5 bowlers bowling their full quota of 4 overs each. And, another fascinating aspect would be that every bowler from Bangladesh team returned with a wicket against his name. Perhaps! You could all blame it on the pitch they were playing on which was hosted by Bangladesh. But still, in a T20 game the pitch hardly matters whether it is the home ground to one team or not. This is truer when it comes to games involving Bangladesh and Zimbabwe.
Likewise, things were not easy for the Bangladeshi batsmen as well when they lost 7 wickets and took until the penultimate ball en route to their successful run chase of 133 on the board. That should not be a matter of worry with the game having been a 20 over affair. Still, Bangladesh have got a lot to improve with their approach not being a match winning one if not for games against West Indies, Zimbabwe and other non-test playing nations. One has to acknowledge the triple contribution of Mushfiqur Rahim who played the role of a captain, wicket keeper and match winner for Bangladesh.
