How much velocity is gained from 1st time to midseason


how many miles per hour are added, on average, from the first time a pitcher picks up a ball in the winter to mid season form?


Hi chew1109,

This is a difficult question to answer because there are many variables.
However, a good rule of thumb would be about 5 miles per year through your high school years. Now, the range can be higher or lower than this depending on various factors including:

  1. weight training
  2. improved pitching mechanics and delivery
  3. plyometric usage and other arm speed and strengthening drills and
  4. genetics

Ideally, what should happen is that you gain strength and velocity during the off season (summer and fall) and do maintenance work through the season. Most high school pitchers that pitch regularly during the season will actually see their velocity decline somewhat during the season. To help combat a significant velocity decline, you should reduce weight lifting sessions from 4 to 5 times a week in the off season to 1 or 2 times a week during the season. In addition, you should allow your arm more time to rest between starts by not throwing for 24 to 48 hours after a start. These steps will help keep your arm working at an optimum by giving your arm time to heal.

Hope this helps,
