Major League Baseball and the players’ union are publicly disputing an MLB advertising push aimed at winning over fans. MLB has launched a campaign titled “Level the Playing Field,” which critics say has become difficult to avoid, particularly through MLB’s television presence. The players’ union argues that the messaging is “perverse,” though the reporting indicates the sides are framing the disagreement around how the campaign addresses—or fails to address—ongoing concerns held by fans.

MLB says the campaign is meant to respond to those fan concerns, presenting it as an effort to explain the league’s position and policies. The articles describe the ad push as part of a broader effort to shape public perception while the union and MLB continue to negotiate and manage the relationship with the fan base.

Across the sources, the main points are that MLB is actively promoting the campaign to bolster support, and the union is pushing back with criticism of the campaign’s framing and impact.
