I see where an 18 year old pitcher was killed in Montana at a Legion game when he was struck in the head by a batted ball. I am not sure if legion switched to the BESR rating, or if the batter was already using one but hopefully this convinces them that they need to make it mandatory if the batter wasn't. It may not have made a difference but yet it may have, we'll never know. Hopefully it makes us more responsible in checking for the ratings before a game

This bat-safety issue must be solved. I've seen enough pitchers get pasted, and many near-misses It is established fact that the ball accelerates when coming off an aluminum bat.The fear of injury has unmeasured negative influence on the psyche of pitchers. They are scared and this likely compromises their skills. A new bat design is on the market, called MetalWood. See http://www.metalwood.com It has an aluminum handle and a wood head. Acceptance by baseball leagues and administrators should be expedited. Besides improved safety, this bat reduces by about 3 years the time it takes an aluminum bat player (high school, college, Legion) to adapt to the feel of ML wood bats. MetalWood also gets us back to real baseball instead of bling-ball long ball and long outs. NOTE; the aluminum bat safety issue applies to fasat pitch softball too. This new generation of girls generate tremendous bat contact. The high school mound-plate distance needs to be increased to the college specs. Pat O'Reilly, umpire, sports researcher |

kids swinging a 33"/30 oz. aluminum would have no problem with a 32" wood bat for a little bit then they can step back to a 33" after a dozen times of BP. they will notice that they arent hitting 5,000 MPH shots back at the pitcher, and they will notice that it makes for a better game. Quote:

Pat: Where do you live that has a different distance from the rubber to the plate in high school?

It should have been http://www.metalwoodbats.com, however the site is under construction.

Pat, I see that you are relatively new to this forum with only a few posts....
I checked out your profile... What is Occupation:Sports Researcher, Sports Officiaal, Sports Inventor??? I understand the Official part but what is the "Researcher" part and what sports inventions are you involved in?

It's time for all these governing bodies (NCAA, NAIA, NFHS, Legion, etc.) to just say WOOD. It is how the games should be played and eliminates all this nonsense about BESR, weight to length ratios and composite materials. When safety finally outweighs $$$$$$$ they will go to it.

Ball accelerates?
"It is established fact that the ball accelerates when coming off an aluminum bat."
I know that the ball rockets off some metal bats much faster than off wood ones, and something has to be done. Even in softball people are being killed and seriously injured by shots off red-hot bats. Softballs are coming off bats at 105 miles an hour, so baseballs must be far above that. One physicist estimated that a ball Mickey Mantle hit off the Yankee Stadium façade was traveling 155 mph (don't know whether he meant at the time it hit the façade or the time it left the bat). That was of course with a wood bat, so who knows how fast they are leaving a metal one these days. But a technical question: Is it physically possible for a ball to accelerate in flight?

I would like to give you an emphatic NO!
But that is not quite technically correct.
A curve ball technically accelerates because it changes direction ==> it gets going faster in that particular direction to which it is curving. This is an acceleration but does the overall speed of the ball increase from the time it leaves the pitcher's hand? If it does it would be pretty minimal and would require some fairly high powered analysis of the ball's flight to prove the overall speed was increasing. Perhaps this would be a good use for the wonderful QuesTech system! Overall does the speed increase during flight... possibly, in a very minimal amount due to the spin of the ball but realistically, NO. A ball does not leave a bat at 100 MPH and increase it's speed so that by the time it is caught it is traveling 125 MPH. Quite the contrary is what happens; the ball decreases speed in the direction it is traveling due to the friction and drag of the air. You can see this in the projected flight of a ball as it leaves the bat and climbs at a nice gradual angle but as it reaches the extent of its upward movement the descending angle in which the ball falls is much steeper than the ascending angle. This is because the ball has slowed down (due to air friction) and at this point in the flight, gravity has a much greater affect/portion of the ball speed than the original impetus provided by the bat. Can the speed increase due to gravity be greater than the original speed? Not on a level playing field. Yes, if you hit the ball over a cliff where the distance the ball falls is much greater than the distance the ball rose into the air. So in the sense that you asked the question the answer is no. I think some of this talk about acceleration has to do with the materials of the bat (given that the COR, Coefficient of Restitution/Resiliency, of the ball is constant). A soft bat, such as a wooden one, dents in more and the dent rebounds back to its original shape more slowly - less energy is transferred to the ball and consequently the ball leaves the bat at a slower speed (for a given speed of the bat). A harder metal bat does not dent as much as the wooden bat and the dent's rebound is quicker - more energy is imparted to the ball and the ball leaves the bat at a higher speed ==> therefore quicker and farther flight and the need for quicker responses by the defense. It is for this reason that highly resilient bat materials become a safety issue for the infielders because they cannot respond fast enough to the increased ball speed. Hope that helps and that I haven't confused anyone. Tony [Edited by DownTownTonyBrown on Aug 4th, 2003 at 03:44 PM]

On it's downward path gravity will overtake friction and the ball will accelerate slightly. Since it is doubtful that it was high enough to obtain termninal velocity as it falls, it should accelerate righ to the point it hits the ground or glove. But the instant it leaves the bat friction and gravity will work to slow it's velocity.
