What do the rules of cricket say?
The reason for this change is that the bells used in the existing WPL also burn at a slight movement, even if both spigots have not completely out of the groove. According to the rules of cricket, the vine falls completely only when both spigots come out completely from the groove. According to the report of ESPNcricinfo, this rule was changed because the bells used in this WPL burn when there is a slight movement, even if both are not completely out of the spigot groove.
Teams were not aware of the rule
Now the third umpire will give his decision on the basis when Bells completely comes out of the groove. The third umpire in the Capitals-Mumbai match, Gayatri Venugopalan, took three runs-out decisions based on this new rule. Reports have revealed that the match officials were told about the change in the morning of the Capital-Mumbai match, which was the second game of the season. However, the teams were informed the next day of the match. It is a bit strange that the teams were informed a day after the match.
