I have been analyzing the 2021 MLB data in my efforts to become proficient with SDQL3 and I plan to document all of the anomalies here so that we have a record. I am willing to assist in the updating of the live database to include the missing data.
I have found that the following 9 games are missing home plate umpire data (HPU). 6 of the games are actually missing all of the game data so correcting the HPU data is not of prime concern for those ones.
