You make good points and a good illustration why I think college is easier to call ball/strikes than HS. No need to expand the zone and it's much easier to be consistent with a more 'true' zone. Always bugs me when HS pitchers want that pitch that's on the outside part of the chalk called a strike (happens a lot) - in college, they know better. And, let's face it, we all probably give in and call that pitch at times because we're 2 hours in and it's still the 5th inning 😜
