Cricket and baseball are like apples and pears.
And what I mean by that is the two maybe sports which use bats balls innings and a few other commonalities but that is where the similarities end thus the skills are not transferable, I can't possible see how a good cricketer would make a good baseball player, the sports are just so different and require a totally different type of athlete.
For example the best batsman in international cricket Sachin Tendulkar and Brian Lara are both around 5'9" and 170bls,a size unheard of compared to top MLB batsman, likewise top blowers (cricket) are usually the biggest players on the pitch and would compare in size to their MLB counterparts but the technique used to bowl and pitch are completely different and don't compare at all.
If this is a true story it is a far fetched one at that, having said that i would like to see how this film turns out..being that I'm a huge cricket fan.
