I think Its B, having 2nd cover. In softball the pitcher is the key to the whole season and the more times she is put in dangerous situation the higher the chance to lose her to injury. Not that i would coach this way but i have seen others that will see that and intentionally try to run into the pitcher, I would like to hope its not to cause injury but we all know there are some coaches out there that do indeed coach this way...I think same question can be asked abut who covers the plate on pass ball. I am a firm believer that the corner that is playing in should be there to cover pass ball if possible just to keep Pitcher out of harms way.
