Actually, Catching Coach, it takes well over 87 MPH to travel the 127 feet in one second. I think you are forgetting the decelleration of the ball in flight, which is about 1 MPH or every 10 feet.
An 87 MPH throw gets there in 1.07 seconds. It takes a 94 mph muzzle velocity to get to second base in 1.0 seconds.
