The 60 yard sprint is a good measurement to have. Home to first times and SB times are also good measurements. 30 yard times are good and so is the 40 yard sprint. However in my opinion the most important speed measurement of all is 10 yards or 30 feet. It pertains to every position on the field. If two outstanding middle infielders were timed at all the various distances, would you want the fastest 60, fastest 30, or fastest 10?
Usually the fast 10 will be one of the best 30s. However we sometimes see great 60 times with slow 10 yard times. So what is more important in baseball... Early speed or late speed? The first tree strides or the last three strides. You could say both measurements are important in different ways... Speed or quickness!
Something very interesting that we have discovered... In some cases we see slower 60 times that in the past would be considered too slow to play at a high level. However they have a good 10 yard time and that tells a completely different story.
One more thing that is important to know... some run much faster in games than they do in workouts. And most every player knows there are certain times they simply run faster than they normally do. This usually happens in games. So we try to get as many in game running times as possible.
