Jeon Jun-woo of the Lotte Giants attempted to do his best Willie Mays impersonation after hitting a ball he thought he crushed for a homerun.

Only problem, was that it wasn’t a homerun and after he dropped his bat and pointed to the sky, he realized, along with the rest of the players on each team that it was a fly out. Whomp. Whomp.

There is such a thing as unwritten rules in baseball, and this goes to show why you respect them.
