Cardinals manager Oli Marmol is ejected after home plate umpire Doug Eddings tells rookie reliever Hancel Rincon to adjust his hat during Rincon’s MLB debut. Multiple outlets report that Marmol disputes the interruption and responds to the umpire after Eddings directs the pitcher to straighten his cap.

Accounts describe the exchange as contentious, with Marmol later calling the stoppage “embarrassing” and characterizing it as unnecessary. Some reports include strongly worded criticism from Marmol toward the umpire, describing the request as a “power-hungry” move. Outlets also note that Rincon is making his first appearance at the major-league level, which places the incident in a high-profile, early-game moment.

One outlet adds additional context the next day: Eddings apologizes to Rincon following the earlier hat warning and the resulting ejection of Marmol. While the outlets generally agree on the core sequence—hat warning, argument, and ejection—they vary in how they frame Marmol’s remarks and the tone of the confrontation.
