Ranking the 10 Biggest MLB Trade Deadline Mistakes of the Last Decade

Key Points:

• The MLB trade deadline is a critical time for teams to either bolster their rosters for a postseason push or rebuild by trading away assets, but mistakes made can have long-lasting negative impacts.
• The Cincinnati Reds' 2022 trade of Luis Castillo to the Mariners is considered a major error, as Castillo continued to excel while the prospects received in return failed to contribute significantly.
• The Padres' 2022 trade for Juan Soto involved surrendering multiple top prospects and, despite Soto's strong individual performance, the team missed the playoffs and later traded him away, highlighting the risk of trading heavily for star players.
• The Mets' 2021 trade sending top prospect Pete Crow-Armstrong to the Cubs for Javier Báez and Trevor Williams is viewed as a significant misstep, as Crow-Armstrong has since become an All-Star while Báez only contributed briefly before leaving in free agency.
• Other notable deadline blunders include the Pirates trading away future stars Tyler Glasnow, Austin Meadows, and Shane Baz for Chris Archer in 2018, and the White Sox trading Fernando Tatis Jr. for James Shields in 2016, both deals heavily favoring the receiving teams in the long term.
