Focus on your home to first speed and your first to third speed. Last year, my son saw many of his private showcases throw out the the 60. Its very hard for coaches to assess a taller kid's speed vs a shorter kid's speed on the bases vs in the field. For example, I saw a 5' 8" kid beat a 6' 4" from home to first three times. In the 60, the taller kid beat him due to distance and stride length. Where do you run the 60 in baseball?
Comes down to quick twitch and the jump. Many great NFL running backs aren't the greatest sprinters.
