Major League Baseball pitchers are signed to pro contracts because they can throw a baseball with more speed than the average human being. Most begin their professional careers throwing their fastball 92 MPH or higher. However, something mysterious happens when pitchers get to the big leagues — over time, they lose velocity. Why?
In every other sport — heck, in nearly every other human activity, athletic or not — people tend to get better, not worse. And certainly, world-class athletes will improve their skill and be at their peak performance when they reach age 25 to 30. But Major League Baseball pitchers tend to LOSE rather than GAIN velocity during that age range and continue to suffer from diminished velocity into their early 30s. What’s the reason?
There is more than one explanation, and in this podcast episode we focus in particular on Los Angeles Angels of Anaheim pitcher Jered Weaver’s drastic loss in velocity. Weaver touched 95-96 MPH when he began his professional career, and now struggles to break 80 MPH.
Listen to pitching motion expert Angel Borrelli explain the reasons why Weaver and other MLB pitchers lose velocity.
