For those who don’t follow cricket closely, there are a few significant rule variations for women’s cricket - namely a smaller/lighter cricket ball and reduced field\boundary dimensions.

There are also implicit limits in the upper end of cricket performance- Elyse Perry holds the record for the fastest womens cricket ball bowled ag 130.5 kph, while Shoaib Akhtar holds the overall record at 161.3 kph. There’s an interesting article here that goes into more detail on the precise physical characteristics that influence bowling, where they define male fasf bowling at >122.9kph and female fast bowling at >97.8, a 30% ish difference: https://pubmed.ncbi.nlm.nih.gov/35259727/

This is all to say that there are very clear and established differences between men and women’s cricket in the interest of safety and fairness already baked into the laws of the game. If you accept that male puberty leads to a disproportionate advantage in bone density/muscle mass vs cis women, then this decision is sensible. The exact numbers are hard to quantify, skill and natural technique plays a huge part in cricket, but on the bell curve of something like pace bowling the risk of a trans woman significantly outperforming cis women is undeniable.
