Answer to “How Fast Should My Son Be Throwing”
The question, “How fast should my son be throwing at age xx” is one that crosses many parent’s minds. We want our son to be successful at baseball, or maybe we see that he’s faster than most of the other kids in his league. It is natural to wonder how he stacks up for his age.
Before we get to some numbers, let’s consider a few important things.
- Be careful of over use and injuries. If your son throws hard or throws strikes, there are a lot of unscrupulous coaches out there who’d love to over-throw your son. Look at ASMI’s guidelines for pitch counts and demand that they be observed. He’s your kid. You have the final say. http://www.asmi.org/research.p...on=positionStatement
BTW. Travel ball is not an absolute necessity to be a good player. But, if you do want to participate, find a good team and coaches who protect players. Search this board’s forum for more information about the pros, cons, value and just plain useless hype involved in the travel ball industry.
- Be careful yourself about over-throwing issues. Too much practice at full-intent can be dangerous. Make sure that they get a lengthy period of rest each year. See ASMI for more information on that.
Now, on to what you came for.
- How hard a kid throws as compared to others can be a bit deceiving. Most every poster on this forum can tell a story about a kid who while young was dominant with his fastball, bat, etc., but who largely fizzled later on. What generally happens here is that a kid has matured early on as compared to his peers, and is bigger and stronger and thus dominant. Sometimes these same kids largely quit growing and the others catch up. So, it can be dangerous to try to identify future Big Leaguers” or project fastball velocity out into the post puberty time frame. Some kids do continue to grow and get better. If they have big parents, then some projecting may be valid.
I’ve seen one guy post a chart on line that purports to project velocity to 16 y/o based on what a kid throws at 8 or 9. NO! There are way too many variables for this to be true.
- How does the kid throw for his particular size? Do you look at him and say, “Man, for his size he really throws it”? Or do you look at him and say, “Man for a big kid, his fastball’s pretty soft”? Those who are soft for their size are often times either not very well trained or not particularly gifted at pitching. If your son is a bit small but throws as hard as a lot of bigger guys that’s a positive. However, if you are 5’9” and your wife 5’2”, then maybe your son won’t be that big and may never have elite velocity.
On that note, if your son is a 5’10” 145 lb sophomore throwing upper 70s low 80s and you have reason to believe that he will grow taller and stronger, then one might be able to carefully project his future somewhat.
Remember to be wary of “Daddy Glasses.”
- It is a bit hard to get real averages for fastball velocities. Quite simply, no one is taking readings of every kid who throws in a game across the nation. What information we have is usually compiled by trainers and some researchers and often times include kids who are already to some degree a bit advanced. So, what’s the true average?
- There’s no substitute for hard work and want-to. Mechanical adjustments and work out programs can help a lot.
- A pitcher should throw as hard as he can while still throwing strikes (in games). Intent is an important part of velocity. At the younger ages, throwing hard is a little more important than throwing strikes. Learn to throw with effort and sound mechanics; then dial those pitches in for strikes.
Now, here is what a few people have had to say:
Steve Ellis - http://www.thecompletepitcher.com/pitching_speeds.htm
10 and below – between 40 and 50 mph.
11 and 12 – between 50 and 60 mph
13 and 14 – “55 mph (on the low side) to 75 mph. A pitcher throwing 75 mph is well above average for this age, and their fastball is at a high school caliber.”
High school – “A high school pitcher can be anywhere from 14 to 18 years of age. This plays a factor in determining an average fastball velocity, however keep in mind that most high schools have a Freshmen, Sophomore, and Varsity program to break up the large age gap. On the average, a typical Varsity high school fastball is between 75-85 mph, although many good Varsity pitchers will be seeing the upper 80s and low 90 range. The Freshmen pitchers will usually be throwing at a comparable speed to the 13 and 14 year olds, and the Sophomores will lie somewhere in the middle.”
