Apparently they just changed that law to make it easier to be given out obstructing field (e.g. batsman changes direction to run between fielder and stumps - if he gets hit in a runout attempt, it’s obstructing field).
This law just looks silly though. Even with the law as written, the batsman isn’t doing anything wrong. There’s an arguable case that he was out under the law, but totally against the spirit and the appeal should not have been made.
Good to see the keeper/captain (who made the appeal) scored 2 off 17 and the Windies lost.
In other news, South Africa can win without Steyn, and Kenya’s U19s refused to chase 436 against NZ and just batted out the overs, scoring 190 for 4.
