Breaking the plane HR theory
 

Been reading and researching online about a recent MLB game involving a batted ball hitting off the top of the OF fence, coming back into play, and eventually being knocked back out of play by the OFer.

The late, great, Mr. Carl Childress responded back in 2001, please see...

My question is this...

If a batted ball hits the top of the wall and continues forward breaking the plane of the OF fence, and the fielder leaps and knocks the ball back into the playing field, would it be considered a HR?
