What happened: The organization selected right-hander Owen Murphy to the major league roster while recalling JR Ritchie to Atlanta. In corresponding transactions, the club designated Carlos Carrasco for assignment and placed left-hander Martín Pérez on the 15-day injured list with a left forearm contusion.

Why it matters: The influx of fresh arms provides necessary coverage as the staff navigates midseason fatigue. Carrasco departs just over a month after his initial promotion, shifting the bullpen dynamics.

What to watch: Monitor the team's usage of Murphy to see if he operates as a spot starter or a long reliever.
