Because Beth Mooney is an excellent wicket-keeper, always keeps in domestic cricket, a senior player in the team, local, knows the bowlers, and will be there for the whole series.
Watched a few of the wbbl games over the weekend. Unfortunately the overall standard is very low, bowling , batting and especially fielding. Yes there are some class players involved, but there is no depth. Some of the players wouldn't make the average u12 Boys club team. Waiting for the hate, but it is a fact.
They are 65 metres as according to the laws of MCC cricket. At the WACA, the men's T20 domestic use the same boundaries. The fence is actually 85 metres from the wicket.
