What happened: Contenders seeking rotation help are weighing trade paths before the cutoff. MLB has used a single trade deadline since eliminating August waiver deals in 2019.

Why it matters: Deadline additions can reshape postseason rotations and determine how clubs allocate prospects. Players must be in an organization by Aug. 31 to retain postseason eligibility.

What to watch: Watch for the first completed starter deal to establish the acquisition cost across the market.
