Archer has been "developing a change" ever since he hit the MLB level, and he has always thrown it 8%-11% of the time...just like this year.
His CH has had roughly the same movement and velocity delta this year that it's always had.
Archer's change is what it is at this point. Or do you think the Braves are experts at teaching 30 year olds new change ups?
Why do you think we got Venters?
