I am sure this has been discussed in great detail in the past so if you would like to direct me to that discussion or add to it please feel free. My question is regarding the 'rise ball'. Does the baseball actually begin its movement towards homeplate on a straight line and then begin to rise? Or is it a perception of the naked eye, because of leaning backwards and the particular release point the ball seems to move upwards?

F.J.,

Thanks for the quick response! I appreciate it very much, however, I am wondering if you could direct me to the peer reviewed scientific literature that states these claims (i.e., a ball cannot rise under normal conditions). Thanks again.
