I guess this ties back into what Zakk mentioned though.
If Rolton developed her game against 140km thunderbolts on a regular basis then she probably would've performed better against men. Like I said in my post above, that's a development/opportunity problem, not a physical one.
You don't need to be a physical powerhouse to be a good batsman (or batswoman

). But you do need good coordination, discipline and reflexes, especially against the quicks.
It's a similar skill set to that of racing car drivers in many respects and women have demonstrated that they are able to compete with men in that arena.
