Wasn't there game where the Cubs' closer was struggling to finish it out and everyone met on the mound and it was reported afterwards Neifi said something, like, "you see this glove? This glove is made of gold. Get him to hit it to me," and then that's what happened?
I might just be imagining it, and a quick Google search found nothing along those lines, but that possibly made up memory is the one cool Neifi Perez moment I can think of.
