A young Yankees fan was drilled in the forehead by a Giancarlo Stanton home run ball on Thursday ... but fortunately, the kid seems like he's going to be OK.
The scary scene all went down during New York's game against the Minnesota Twins at Yankee Stadium ... when Stanton hit a laser beam to right field.
The ball was absolutely crushed -- it left the park in less than 3 seconds -- but on its way down, it collided with a kid's face.
