Fans will go to great lengths to catch a baseball, just make sure your kid is safe first.

In Monday’s spring training game between the Mets and Marlins, Chris Young laced a ground-rule double into the right-center field gap, and as the ball rolled into a picnic area, one fan let go of a wagon holding his kid and tried to retrieve the ball.

The wagon went rolling down the hill and crashed into the fence. The fan didn’t even come away with the ball, either.Cameras later showed the kid was OK, but the dad may be in bigger trouble, with both his son and his wife.
