As Jon said baseball showcases etc rely on the 60 yd. dash as a measure of pure speed. Some utilize hand time or a hand held stop watch and a more accurate way is FAT time or fully automatic timing. FAT timing takes away the human element. Most athletes do not like FAT times and most educated and progressive coaches love it. It is the only objective way to time. FAT times will typically be .2 - .6 slower than hand held times. You can see why athletes don't like this utilization.
Speed is a function of mechanics not unlike hitting or throwing. Speed must be taught by a coach who not only can recognize the deficient mechanical issues but be able to correct the issues through proper drill sequencing and muscle activation. Some are blessed with more available fast twitch fiber than others but you can be taught to be faster and run more efficiently than you currently do regardless of age.
Athletes who 'specialized' in baseball at an early age usually have not had any exposure to movement mechanics. This might be where 3.9's assumption that baseball players are slower than football players comes from.
How important is speed in baseball? I have had college and pro scouts come up to me when testing athletes at a showcase and ask if there was anyone who ran a sub 7.0 sixty. I knew the answer but I wanted to hear him say it...I asked 'Why do you ask?' His reply - "I don't care if he knows which hand to put his glove on, if he can run I can teach him to play baseball."
I have tested literally tens of thousands of athletes and approx. half of those baseball players who had aspirations of playing at the next level. I have only seen
2 sub 6.6 sixties utilizing auto time.
Missouri dad - congrats on the 6.63 your son ran. That is exciting and should get some attention.
