Mariners Moose Tracks, 8/1/25: Mason Miller, Carlos Correa, and Griffin Jax

Recapping a whirlwind of a deadline day.

The trade deadline has come and gone, and it was one of the wilder ones in recent memory. The Padres dealt seven of their top 17 prospects; the Yankees and Tigers rebuilt their entire bullpens; the Twins, Diamondbacks, and Orioles completely tore down; and the Rangers and Astros unfortunately got better. Let’s get to all of that and more.
