Rotational Changes & Injuries

The New York Mets demoted All-Star David Peterson from their starting rotation and replaced him with Sean Manaea, a move that comes despite Peterson's strong performance in 2025.

Meanwhile, the Minnesota Twins have designated Simeon Woods Richardson for assignment amid struggles, recalling rookie John Klein to bolster their pitching depth. On the injury front, Seattle Mariners catcher Cal Raleigh, who was placed on the injured list May 14 with a right oblique strain, took his first swings since aggravating the injury, offering hope for his return to the lineup in the near future.
