Designated hitter obr rules explained?

[Micky]

I am struggling with the DH rules. For high school there is a great video from Umpire Classroom: 

 

But for obr I cannot find a good explanation of the rules. Only pretty generic explanations. But not diving deep like in this video. Does anybody know of such a video? Or an article that explains it in depth with examples etc?

TIA

Curious (not flaming back that it's a dumb question): who does OBR w/ DH that doesn't have their own ruleset? Men's league?

[Micky]

I live in Holland. We don't have High school or Collega rules. We only use OBR for all age groups. With a few little exceptions for U12, U15 and U21. So from the highest league till Beeball, we use OBR. But for example, infield fly only starts at U15.

Got it. I don't expect you'll find in depth analysis since only Pros umpire deal with straight OBR with no added layers.

The original rule seemed straight forward (at least according to Refsports):  https://www.refrsports.com/blog/the-designated-hitter-rule-in-mlb-how-it-works

Once a designated hitter is listed in the lineup, that player must hit for the pitcher throughout the game, unless substitutions or double switches change the situation. A few key points:

• If the DH takes a position in the field, the team loses the DH spot for the rest of the game.
• If a pinch hitter or runner replaces the DH, the new player becomes the DH.
• The pitcher can still hit for himself if a team chooses not to use a DH—but this is almost never done at the professional level anymore.

 

 

Ohtani added complexity though. This article discusses the 2022 2-way player changes:

Never realized that. There seems to be a lot more video learning material voor high school and college rules. If OBR is indeed mainly for MLB pro umpires, they don't need the video material, I guess they have had enough training and support from their organization.

Thanks for the articles!

Somewhere in a building in Indianapolis, IN a group of men and women just got a chill. Like, an impending dread that their purpose(s) in life is no longer needed. Not, not their lives were no longer needed; nay, that there isn't a reason, or purpose, for them to be sitting in that room, in that building, mulling over what they mull.

I disagree... they either ponder, ruminate, or muse.  And, after all that, we know they pontificate, but, they never mull.

I guess this is humor we don't get at the other side of the ocean. 🙂

The nice thing about strict OBR is that there's no reentry. It's a bit easier to manage.

If I remember correctly a past MLB illegal reentry penalty was missmanaged.
