Hmm, fair point. I can see how increased ball velocity and decreased reaction speed could make an injury more likely. Nevertheless, I still have these doubts:

• How much of a difference actually is there in reaction speed? I have a hard time believing that there’s enough of a difference for a biological female be unable to dodge a throw where a biological male would.
• Going with the previous question, is this alleged difference in exhaustion actually observed to a great extent among professional cricket players?
• Are these safety factors really significant as to be part of a reason to ban transgender players? If a cis woman came around that bowled significantly faster than other cis women in the sport, would it be reasonable to want them banned from the sport or to portray them as a threat to other players?

Unless there really is some big safety concern, still seems absurd to ban people on these metrics and tell people that you’re protecting the other players by doing it. With the evidence I’m aware of, it still seems minimal to me, and we’ve seen BS reasoning for banning trans women in other women’s competitions (e.g., chess). While I can’t say with confidence that there’s no decent argument in support of a ban, I still don’t think safety is part of it.
