That's not even the issue. A ball off the top of the wall is NOT a home run either way. The issue was whether or not it hit the ivy behind the wall and then bounced off the top of the wall. umm the announcer said that at this park if the ball hits all yellow its a homerun thus if it hits the top of the wall it IS a homerun. If it if hits the ivy behind the wall wouldn't that be a homerun since it went behind (or over) the wall. Well then that announcer is wrong. At every ballpark, the yellow line on the wall denotes the point the ball has to clear to be a home run. Hitting all yellow and coming back into play = no HR. Seriously, it takes two seconds to look up the Miller Park ground rules: The play being discussed here happened about 200 ft from the left field corner. http://www.ballparkdigest.com/visits/miller_park_2.htm Scroll down from the link above, and you'll see a picture of the area being described in the ground rules (5th pic on the page). It's a vertical pad that runs the first few feet above the wall, in front of the foul pole. Earlier on that same page is a shot of the RF wall. You've gotta hit the ball completely over those yellow pads for a HR, just like in all ballparks. But at least there can be cases where a ball that hits the yellow line and comes back in play is a HR.
