Watching cricket and you get similar ridiculous statistics in Tennis.
"He's bowling at 90 MPH" at 60 a ball would travel 29 yards or 1.3 lengths of the wicket, so at 90 the ball will travel 1.95 lengths of the pitch. yet the batsman has time to pick where the ball will bounce, decide on the shot, adjust his feet, raise the bat and swing it, all in half a second.

Not sure why that is useless or ridiculous, it's very factual and better than saying he/she has very little time to do all that. Cricket especially they have a lot of time to fill so there are far more useless facts mentioned that you could have picked on.

what I'm saying is the players couldn't react that fast at 90 mph the ball travels between the wickets in 0.5 seconds. The average reaction time is 200 milliseconds so 0.3 seconds to decide on the shot move the feet and bat and play the shot it just couldn't happen that fast.
If The bowler is running at 20 MPH to accelerate the ball to 90 MPH would mean that in the course of a rotation of the arm from to in front of the body . ie in 1/2 Pi * 6ft ( assuming a 3 foot arm length ) so approximately 10 feet the ball goes from 0 to 70
70MPH is 102 feet a second so given a constant acceleration that's an average of 51 feet per second so 0.2 of a second for the bowling action.
The G forces would also be enormous 1 g = 22mph in a second we are proposing 3 times that in 0.2 seconds so 3 * 5 = 15G

Then friction gets to work both through the air & off the pitch so the ball will not arrive at that speed. Reaction time without friction .48 sec - thats elite sportsmen for you cricketershub.com/how-long-to-react-to-cricket-ball/#:~:text=This%20is%20a%20speed%20we%E2%80%99ve%20seen%20regularly%20from,how%20do%20they%20make%20it%20look%20so%20easy%3F

On the first point: the speed is measured; its a fact (yes with some leeway for in accuracy). Only the very fastest bowlers get it above 90mph, and they do not manage it every ball but may manage it when they are really 'in the groove'. With respect to reaction times: there are two critical points: 1. Top sports people's reaction times are faster than the general population. 2 its a well known thing that in a sport such as cricket (and I suspect the likes of baseball), its erroneous to think purely in terms of the time taken from release of the ball to the point at which they have to play the shot. The batsman will be reading the bowlers arm movement, hand position, approach to the wicket, and working off the knowledge of previous balls and in effect is making judgements about how the ball is likely to pitch (where on the wicket) and what it is likely to do and what shot to play even as the ball is being released. Otherwise they don't stand a chance: forget about the time of travel from release by the bowler, its going to be an even shorter period of time from the point it impacts the wicket and does what it is going to do post impact. A batsman can easily misplay - and be out from - a slower ball from a fast bowler, even if he has been happily dealing with the faster balls. So though he had more 'reaction time' its his reading of what will happen, not what is happening, that he falls foul of.

Bracknellboy is of course correct, and that's why if you throw rather than bowl you are no-balled. Throwing means the arm straightens with a jerk so the batter cannot use the same prediction from the trajectory of the arm, and only gets 0.5 seconds to plan the shot. If bowlers were allowed to throw at 90mph then batting would be impossible.
