What is the reason for such big scores in IPL?

At the time of the toss, the teams have to list five substitutes. If there are not less than four foreigners in the starting XI, the substitute must be a local. Teams are using this rule to score quick runs in the last few overs.

Mithali says, 'We have seen how it is helping teams to put up big scores. It is helping the teams batting later, especially.'

Along with Hyderabad's two record scores, this season also saw Kolkata Knight Riders score 272/7. They made that score against Delhi Capitals. In that match, Sunil Narine, who opened for Kolkata, played an innings of 85 runs off 39 balls.
