Don't worry, it's not the wave.
(We don't need to get into the fan "celebration" that made its way around Wrigley Field during Sunday's Cubs-Marlins finale.)
But, there was a really nice moment in the stands.
Marcell Ozuna hit a fly ball down the right field line and wound up going foul, through the hands of a Cubs fan and ricocheting back onto the field. So Nate Schierholtz goes over, picks up the ball, tosses it back into the stands, where a Marlins fan catches it.
The Marlins guy, being the good person that he is, turns around and tosses the ball to the distraught Cubs fan, whose eyes light up like a 4-year-old on Christmas morning.
But the story doesn't end there. There was one more kind gesture in store:
If that doesn't at least make you say "aww," your heart may be made of ice.
