India and Australia decided to implement the ICC's proposed one-day international rule changes in their seven-match series from Saturday itself. The new rules, supposed to come into effect from October 1, were advanced to avoid a mid-series adjustment. In June, the ICC had ruled the following changes in ODI playing conditions:
An additional fielder will be allowed outside the fielding circle during the second or third Powerplays.
If an ODI innings is reduced, the numbers of overs making up each of the three Powerplays shall be reduced proportionately.
If a bowler bowls a front foot no-ball, the following delivery will be deemed a free hit and the batsman cannot be dismissed by the bowler from that delivery. He can only be run out.
There will be a mandatory change of the ball after 35 overs of each innings; the replacement will be a clean, used ball.
The ICC had also increased the stipulated minimum boundary sizes for all international matches, with the square boundary measuring at least 150 yards from one side of the ground to the other (minimum 65 yards on one side; previous total minimum size was 140 yards); and the straight boundaries 70 yards at both ends (previous minimum was 65 yards); maximum boundaries to be used allowing for three yards between boundary rope and advertising boards up to a maximum of 90 yards from the centre of the pitch.
