Ball Exit Speed Off the Tee

It is just one way of measuring batting performance while taking away the variable of a pitched ball. (velocity, location, etc) If you have ever been to a showcase and watched BP, many times the batters performance has as much to do with the guy throwing BP as the hitter. (for two equal hitters, or the same guy in different rounds) They did this at the Stanford camp and I believe the results were in the 70-90MPH range. They could measure bat velocity, but this gives a more representative figure to what someone might see in real life.

1. You mean off the tee or from pitching?

2. When you say "this", you mean a radar reading off the tee?

Thanks for the insight

Yes off of a T. They also did BP, but put all of the ball velocities off of the T in their database along with other measurements.

You should consider varying bat weights and bat material types. Ex. wood would be approx 5-8 mph slower than non-wood.

So be careful comparing exit speeds unless you are using the same bat and the same pitch speed (0 is easier).

Agree with BOF that exit speed of the ball is a better indicator than bat speed.

My son hits off the tee throughout the winter in the garage and we have radar setup behind the screen.

1) It helps him focus on quality swings when hitting off the tee.

2) he has used it over the years to test different bats, sizes and weights of bats to help determine what bat he uses.

Just got everything setup in the gargae a couple weeks ago and with his 32/29 school bat he is conistently 70-74 mph off the tee. With wood bat of the same size and roughly same weight 67-72 mph. So I see about a 4-5 mph difference between wood and non-wood bats.

I have no idea where these numbers are for other kids his age but I am not too concerned about that. we use it as a tool to make sure he is working hard on every swing, also can tell when he starts getting tired and swing starts to break down and makes it easy to track improvement from year to year.

denjake, that's the way to do it. Very nice.

This link has some good info for averages by age group.

Wow,

Non-wood bat off the tee:
--70s,low 80s 9th
--80s JV
--mid 80s Varsity

These values seem high. No wonder they want to reduce the "pop" in non-wood bats. I can only assume that the college (D1) numbers would be 95 and higher w/non-wood bats.

Exit speed off a tee can result in long swings

Short to the ball, long through the swing.....

The exit speed velocities are not high. We have been evaluating exit speed off T for the past 2 yrs. My sophomore son has worked really hard this off season. His exit speed off of a T has improved from his freshman year by 6mph using wood. He is consistently gunned at 88 during his bimonthly lessons. I think this is due to his work in the gym and just the natural maturation process of being a teenager. His goal is to be 90+ by his Junior year.

OK - trying to get a grasp of where my son is. They are having tryouts now and although my son tore his ACL/MCL in football and is unlikely to play until May - he has been cleared to hit. They measured exit speeds today and he hit 91mph off a tee (metal bat) which seems to be really good from reading the above posts.

 

For the last 3 months we have been swinging from a seated position and using mostly upper body and working on quick hands  - it seems to be working well as he was one of the highest on the team. In the last 2 weeks he was cleared to swing away (as long as he is wearing brace). Looks like working on hands and swing path over the last 3 months has worked out well.

The highest one i've ever measured (high school) was 94 with a metal bat. This kid wasn't a very good hitter but he had a tremendous swing and was very strong... he had only 1 eye due to an accident when he was about 12 yrs old... by the time he was a senior he became frustrated with baseball and gave it up.
