Mariners Trade Deadline Outlook: Minor Moves Expected
Seattle holds a +24 run differential and a one-game AL West lead at 47-46, but their rotation shows vulnerability—Castillo (4.79 ERA, 0.329 xwOBA) and Kirby (3.76 ERA) are underperforming while Miller (1.71 ERA, 0.226 xwOBA in 8 starts) suggests depth exists. Any deadline additions likely target bullpen depth or bench help rather than franchise-altering trades.
