RB - been curious about that. Specifically wondered if he had been applying his philosophy of staying back in the box to everyone and how what was received by them?

Was all about hitting bombs. No situational mindset. Developed hitters but not a well rounded offense.

I'm curious to hear some thoughts and opinions on exit speeds...
How much emphasis are you putting on this?
I've measured a few of my players recently off a tee with my pocket radar.
I've got an 04 girl that is exceptionally small in stature. She's 4'10 and 85 lbs... I Know, its not a typo. She was able to reach an exit speed of 59mph!!! (has never came close to hitting a dinger) While others who can hit the occasional bomb are getting numbers more like low to mid 50's. My dd however is the largest girl on the team, hits #4, tons of power, dingers are the usual for her... Her exit speeds average 65mph?
Some contributing factors.... "hotness" of bat, bat speed, overall player strength/power...
Is there a formula that translates mph into approx ball distance?

I saw a HIT-TRAX video that looked like a video game. It could calculate the angles, bat speed, ball speed, and exit speed then show on a screen the balls flight path and distance... looked amazing. Price is way too high for home use...

Any thoughts on a formula?

Does a live pitch ball slow her bat down at impact? I was seeing that with my dd (who has a similar build) with her blast motion sensor.

All bats slow down at impact. It's all about the physics. A bat has no effect on the ball after it leaves

You can fool a pocket radar off a tee by popping the ball up when the radar is positioned for a line drive. The speed will read significantly higher than actual.

I never said it happened after the ball left the bat. It happens as the ball is colliding with the bat. Strength plays a large part in how much that bat gets slowed down and how much the barrel/ball will compress at impact.

Bat speed and ball exit speed are things I monitor approximately once every 10 to 12 weeks. I will typically measure 20 or 25 swings and utilize the average of the results. I use a Zepp for bat speed and a pocket radar for ball exit speed. I really have two purposes for the measurements. First, I like to start with a baseline and track improvements throughout time. Second, many of the hitters I work with like technology. So sharing that information with them helps keep them motivated to improve.

I believe this is where power comes from. Obviously, your bat needs to be quick enough to get to the pitch and put 'good wood' on it. but the ball is truly driven by the speed of the bat that split second the ball sits on the barrel. not only the barrel/ball compression but how fast the barrel/ball is already moving forward as the two explode back against each other.
