If any part of the ball enters the strike zone it is a strike.Depending on rule set, the strike zone is from the armpits to the top of the knee and the width of the plate. And, the black edge to home plate is not part of the strike zone. But, you would have people screaming if any umpire actually called a strike at the armpit.
Every umpire is going to have a slightly different personal judgment of the strike zone.
Not true for NCAA!
