Obviously it’s not a requirement but it makes the game easier to follow and more enjoyable for me.. Some umps give locations. Some are very demonstrative, energetic, and easy to follow. Others are meek and quiet and you have to guess or ask somebody what the call was. Not as enjoyable.We are not public address announcer, we call balls and strikes, not high, low etc.
Like anything else personal preference. Some people go above and beyond and some do the bare minimum.
I would hope most umps enjoy the sports they choose to participate in. It’s a way to stay close and still be involved in the sport.
It seems there is a percentage of umps out there with control issues looking to supplement their income.
Always great to see umps that are approachable and willing to teach and learn themselves.
