I hope we get a full 5 days play in the last test match of the series.
I don't think so. Third match is scheduled to start from 21st August (this Friday) and the venue is the same (The Rose Bowl, Southampton). As per the weather prediction, widespread rains are expected for all the five days. I will be really surprised if the outcome is anything other than a draw. But please don't get disheartened. We have the T20I series starting from 28th.
Since the venue is same does not look good for the prospects and England would have wanted to win the series by like 3-0 or so or atleast would have tried to do the whitewash if match would have happened without any rain interruption. Unfortunately, that is not the case and England may still win the series but by 1-0 assuming third one ends in draw.
