The Philadelphia Phillies aimed to strengthen their bullpen and outfield before the 2024 MLB Trade Deadline, but their acquisitions have performed below expectations. Austin Hays, a new outfielder, has struggled and faced injuries. The trade for closer Carlos Estevez, however, might have the most significant negative impact on their season.

Estevez's regression shows in his performance metrics post-trade, with a noticeable rise in his WHIP and walk rate. Although his current ERA seems respectable, deeper metrics suggest he may not hold up under postseason pressure. The organization may need to rethink its closer strategy to improve their chances in October.
