YANKEE, no outlet of which I am aware has Umpire info for the first game of a series.
However, once you know the umps for Game 1 of a series, you will know who is going to call the subsequent games.
They rotate clockwise. The first base umpire will call the plate in following game.
Crews change with each series, so you can only use this info for games after the opener of a series.
