As you’re probably aware by now, the start of the 2022 Major League Baseball season will be delayed by at least a week, as the owners and the players’ union continue their standoff. If there’s any silver lining to that development, it’s that it forestalls at least for now, the advent of advertising on MLB uniforms, which was widely expected to be part of the new labor deal.
This probably just delays the inevitable. The two sides will eventually find common ground, and most inside observers agree that the common ground will likely include uniform ads. It's not a completely done deal (the continued bad faith and suspicion between the two sides may be our best hope of avoiding uni ads), but it’s still the most probable outcome.
