Padres bolster rotation with Robbie Ray and Casey Mize at the 2026 deadline, see the 3 critical roster moves San Diego must finalize now. Preller stayed true to form at the deadline, landing rotation reinforcements Robbie Ray and Casey Mize without dealing a single player off his big-league roster. San Diego is sitting right on the playoff bubble at 61-57, and the front office clearly bet that shoring up an injury-ravaged rotation would matter more than a blockbuster splash. Preller's deadline strategy was low-risk by his own aggressive standards, betting that rotation depth alone could push San Diego over the bubble. Get those three decisions right, and the Padres have real positioning to hold onto that final wild-card spot.
