What happened: Philadelphia enters the final trading window after its internal options failed to provide enough production. High asking prices could force the club to choose between an overpay and leaving needs unfilled.

Why it matters: The Phillies need outside help to strengthen a roster built to contend in October. Any premium paid now would reduce the prospect capital available for later moves.

What to watch: Transactions must be completed before Monday's 6 p.m. ET deadline. The size and cost of Philadelphia's additions will define its approach.
