Arm Speed

Based on simple physics, I would think that with a crow hop/more momentum, it is easier to throw harder.
(ex. Trevor Bauer in warmups)

People with a large difference in OF throw speed and mound speed probably have mechanical issues that need to be addressed.

I guess what I was trying to determine was that if you can manufacture that much arm speed to throw that hard (93)from the OF is it in your arm to throw that velocity from the mound if you were to gain arm strength and maturity. Only a young 16 year old sophmore and has topped out at 90 on the mound.

I'm not sure it is going to be a direct correlation as I believe Jarred Cosart of the Astros was the first guy to ever throw over 100mph (101 actually) from the outfield at a Perfect Game showcase several years ago and although he is a prime pitching prospect I think he tops out in the 95-96 range now from the mound. Perhaps PGStaff can correct me if my memory is wrong about this particular case.

I was at that showcase in Ft. Myers and Cosart hit 101. He was on Bum, Jr.'s team. What I remembered was what Bum, Jr. said about how humble and polite Cosart was, a true teammate.

Thanks ThreeBagger, Bum. Thats what I was curious about. I was looking for the correlation between the two. Appreciate it.

After spending a lot of years working with my son and being around a lot of pitchers I am of the opinion that arm speed is one of God's gifts. Some have and some don't. If you have it from the OF - then you will have it from the mound. (with some mechanics help) When my son was 16 he went to a PG event and was clocked at the same velocity on the mound as from the OF. (He is a two way OF/P) I don't really know the OF/Pitcher ratio, on one hand a crow hop will give you a boost, but throwing downhill from with a push off should also help. Bottom line if someone is throwing 93+ from the OF then that arm has a lot more value to a team on the mound than throwing out 2-6 runners. (per SEASON)

I agree. Furthermore, I think if Hunter10's son has thrown 93 from the outfield he has the raw tools to throw 93 from the mound, BUT (big but) throwing is not pitching. Pitching mechanics don't have a small role in this, pitching mechanics have a huge role in whether he will be able to do it and be effective. If it weren't the case, we'd see alot of catchers or Hunter Pence (I cringe when I watch that man throw) on the mound.

My son hit 92 from a crow hop but maxed out at 87 from the mound at a showcase this summer. I believe the momentum you get from moving forward with the hop is hard to make up with going downhill.

I may be wrong though.

There are a few kids who throw the same velocity from OF or the mound. I think when that happens they have worked on pitching much more and they don't utilize as good of mechanics for the outfield throw.

Nearly everyone should throw with more velociuty from thye outfield. Even some very good pitchers. There are no pitching mechanics that can fully replace the momentum they get running in on a ball and crow hopping. The fast arm gets even faster with the body action involved in throwing from the outfield.

A fairly recent example would be Kaleb Cowart (1st round pick by the Angels a couple years ago. Kaleb was an infielder/pitcher and was drafted as a 3B. He threw easily 90+ across the infield and mid 90s on the mound. He decided to get into a contest we held and threw 100 mph from the outfield.

Obviously being on the run and crow hopping doesn't allow for as good of accuracy as a pitcher requires. But it sure puts you in a position to throw your hardest. Going back on a fly ball is a different story, or even standing still. Best velocity is from fielding the ball with momentum towards the throw and crow hopping with a long arm action. Pitchers just don't have that luxury.

Appreciate all the opinions on the subject. Makes lots of sense with the crow hop and without. Great examples by everyone. We have a couple more years and will take note on both velo's.

Arm speed can be generated. The body is connected from head to toe. If you learn how to manipulate the hips and get them moving ahead of the upper body it forces:

1. The arm to redirect and change directions more quickly.

2. Creates momentum

3. Creates a rubber band effect between the hips/torso/shoulders/elbow

Think of it as peer pressure. The arm wants to hang out with the hips and if the hip decides he's going to "speed up", I promise you the arm won't be far behind.
