One of the talking points that was seemingly least divisive between players and owners during CBA negotiations was the expansion of the designated hitter to the National League. That was one of the first changes that they appeared to agree upon, and now that they’ve finalized it, the concept of pitchers hitting in MLB games is all but officially dead (aside from mid-game DH removals and two-way outliers like Shohei Ohtani).
Obviously as an AL team, the Yankees have only dealt with pitchers hitting in interleague and World Series games during the past couple decades.
