Batted Ball exit speed

I do not know the numbers for BBCOR, but the thought behind moving from BESR to BBCOR of course, was to get the numbers closer to Wood.....

Since I do leagues using BBCOR and Wood, I can tell from my position behind the pate that moving from BESR to BBCOR did work....

I still see hits of all kinds.....homers, doubles and triples etc.....the only aspect i see not addressed is that balls miss-hit with aluminum can still go fair, yet that same contact on wood can more often result in foul balls.....

I did find this informative link, however the data for high school was updated in 2010. Most high schools went to BBCOR last spring - 2012. So, I wonder if the info for hs players using non-wood is for BESR models?

And since the MLB numbers say 2009, I would assume the same date for College players? Also, pre-BBCOR which was started in 2011 for college players.

My best guess is that you can subtract 5-7 mph exit speed from BESR to BBCOR.Is that fair?

I think I found the answer to my own question. I found a Demarini Top 96 evaluation sheet posted online.

"Based upon hitting a baseball (line drive) off a tee with BBCOR bat"

Exit velocity speed for High School: 63-78 with 69 as average for HS

A range of 82-93 for college. 87-89 as mid level for college

Pro level 102

If you check the Combine scores at this site http://www.ninebaseball.org/Wordpress/ you'll see some of the exit velocities by grad year.  It's not a large sample, but you may start to get a better idea.  Brought 2017 son to a combine there last month.

NYdad2017,

Thanks for the link. I spent some time looking at the combine numbers for exit speed and it looks like the info from Demarini was pretty much on target. At the various ninebaseball combines this spring, there weren't a lot of kids with exit speeds at 85 or higher. Pretty much a lot in the 60's-70's.

I like the different drills they use for their combined score, especially the way they run a 30 yard drill for their speed test. A more realistic way of measuring speed for baseball in terms of what coaches actually want on the basepaths.

Anyway I can help.

I prefer the series of tests that they did as well.  Obviously the 30yd is a more realistic gauge of what most kids will do when playing baseball.  They run home to 1B a heck of a lot more times then they run from home to 2B, which wouldn't be in a straight line anyway.  

The vertical jump and 5-10-5 are also good indicators of leaping ability and lateral quickness.  

Overall I thought it was a pretty good series of tests.

Here is an older post that I found using the Search function.

I like that they were measuring exit speed, however, this was in BP off of BP pitching.

So the exit speeds will be higher off of a pitched ball than off a tee according to info in the link provided by

Bolts-Coach-PR: http://www.efastball.com/hitti...-speed-by-age-group/

How much faster, I don't know. It's all relative to the pitch speed.

My son had an option of using a wood or bbcor bat at the combine.  I told him to use bbcor as it appears the velocity should be greater off the tee with that bat.  When we got there all of the other kids were swinging bbcor as well.

When a baseball is hit squarely the exit speed will be higher than the pitch speed.  This happens all the time when a pitcher who hasn't throw a pitch over 85 registers a velocity in the 90s.  Of course that is the velocity off the bat when that happens. Unfortunately, sometimes parents will see that velocity reading and think their son just topped out at 93 mph despite no other pitch reaching above 85.

Just like the questions regarding average HS pitching velocity, it is impossible to know the average exit velocity.  I will say this... based on the 69 mph average for high school mentioned earlier, that would mean the average pitching velocity would be somewhere around 65.  I do not believe that number at all.

It really doesn't tell us anything unless the ball is squared up. A hitter could make contact 5 times, once at 60, once at 65, once at 70, once at 75.  Then square one up and register 95 mph. It's the 95 that shows his ability, not the foul balls or weak ground balls. His average on the first four would be 67.5 and that would be very misleading for someone who can generate the bat speed to hit the ball 95 mph.

I'd assume that's why they prefer that kids hit it off the tee.  For consistent numbers?

Yes, the 69mph average that I referenced was off of the tee. This info was from a Demarini Top 96 evaluation sheet I found online. The rating was for exit speed off of a tee using a BBCOR bat.

what would you suggest for a player to improve exit speed?

same player with the same model bat 33/30 or 31/28

unfortunately, we are numbers drive and not performance oriented, although there is certainly a connection, its not the absolute truth

thanks
