After Justin Ruggiano's home run landed, Wrigley Field's ivy generated a fresh replacement baseball

As far as ballparks are concerned, few have as much character as Wrigley Field. It's one of the most historic baseball cathedrals still in operation, for sure. 
Part of its strong sense of individuality comes from the bricks and ivy that adorn the outfield wall. Ivy is thick, and can sometimes obscure whatever's nestled inside it. It's happened quite a few times, actually, the ivy just eating up a baseball as if it were ravenous and past its feeding time. 

Judging by what happened in the Cubs' 6-4 loss to the Giants on Monday night, however, might the ivy actually have had enough to eat? Justin Ruggiano crushed an eighth-inning homer over the wall and into the netting, but while the play was developing another popped out of the ivy like it was no big deal:

That is a big deal, though. I mean, really, the possibilities of when and where this ball became lodged in the ivy are endless. A wayward pregame long-toss gone awry? A double hit by some now-legend back in 1982? Who knows. 
Maybe, though, the ivy actually does generate fresh baseballs? In this case, that'd be a great help, considering Ruggiano's homer lost another one over the fence.
Nobody knows for sure ... but it'll probably happen again in the future, so we'll see what happens.
