What age to start throwing from knees?

Correct with a slight caveat. The best have crazy velocity. They can afford to put a little less effort in gaining ground. Each foot of ground gained is equivalent to about one mph.
It makes zero sense to take more time to get rid of the ball. Zero.

Some quick math* comparing a 60mph throw to a 65mph throw, and I get a difference of about 0.1 sec for a 90' distance (approx. home-2B). The catcher would have to make up over 5' on the ground, with no time lost in the catch-release, to make up that 0.1 sec. My DD is making up twice that in her knee throws just by being quicker to get rid of the ball. Conclusion: Get that ball out of your hand as quickly as possible.


* My math skills aren't excellent. Maybe @pattar can sort it out if I'm a long way off.

Dont expect more out of person like 625error pushing their personal agenda. Other than more of their agenda. Its not about whats really happening in the game for them.

Ha, your lining yourself up to discredit my opinions based upon a metric that you know I don't have.
Not in the slightest. Thats not my game. I'm simply trying to educate catchers, parents, and coaches based on a lot of experience. Thats how we all get better

My question was I response to your comment on velocity and how much it matters. Pop time is a number based on exchange time and the time of flight delivering the ball to a base. The two numbers are married at the hip and can never be separated

So a fast exchange can afford a slower ball velocity and a slow exchange requires more velocity. Again, were looking at numbers. The fastest exchange on a softball player I ever shot was .93 sec. Very high level catcher! Some may be faster, but I see her as extraordinary. The fastest baseball player I ever shot was .87. Again extraordinary and a very high prospect.

Now the fun part. We have to take those numbers and deduct them from pop time. No way around it. The softball pkayer I mentioned has a 1.9 pop time cruising(some faster some slower). That means she must have a nasty arm to get that ball to 2nd. That means she's throwing the ball GAME TIME at or around 57MPh. Fast! In practice ive shot her at 63.

I was referring to softball distances based on a 86ft throw. Again were talking about free money. No change anywhere other then trying to gain a little ground. Zero time to exchange added

WHAT? .93 is SLOW.. Look, my DD is 13yo in this video from 8 months ago. It is just a routine throw down. She doesn't cheat too much and from pop to release is .765sec.

Game time! There's a big difference. The fastest MLB player I've ever seen shot was .71. Thats in the realm of Realmuto and Molina middle of the road times. Funny to my knowledge Muto has the fastest pop time recorded

I rounded up to 90' for the sake of easier math, and the fact that the C is often a little behind the plate when they throw.

It's not "free money". The right foot travelling forward to "gain ground" takes time, which is going to delay the throwing sequence, and extend the time from catch to release. Video after video of the best in the game shows them getting their rear foot on the ground with a short move, under their torso, not a big move forward. Get that foot on the ground as quickly as possible!
