The St. Louis Cardinals appear closer than ever to parting ways with superstar third baseman Nolan Arenado. While Arenado’s no-trade clause and preference for certain teams complicate matters, a proposed three-team trade involving the Philadelphia Phillies and Seattle Mariners could resolve key issues for all parties involved.
Bleacher Report’s Kerry Miller outlined a deal that would send Arenado to the Phillies, Alec Bohm to the Mariners, and highly-touted prospect Colt Emerson to the Cardinals. Emerson, a 19-year-old shortstop ranked as the No. 35 prospect by Bleacher Report, represents the kind of talent the Cardinals could prioritize in a post-Arenado era.
Breaking Down the Proposal
Arenado to Philadelphia
For the Phillies, adding Nolan Arenado would be a game-changer. The eight-time All-Star and 10-time Gold Glove winner brings elite defense and consistent offensive production. In 2024, Arenado slashed .283/.341/.509 with 30 home runs and 105 RBIs. Pairing him with Bryce Harper and Trea Turner could give Philadelphia one of the most formidable lineups in baseball.
Bohm to Seattle
Alec Bohm, an All-Star in 2024, offers the Mariners a younger, more affordable option at third base. The 27-year-old hit .280 with 18 home runs and 82 RBIs last season. His solid defense and consistent bat would fit well in Seattle’s long-term plans, especially as they look to contend in a competitive AL West.
Emerson to St. Louis
For the Cardinals, 2023 first-round pick Colt Emerson could be the centerpiece of a much-needed rebuild. Emerson boasts an .838 OPS across 94 minor league games and impressed in the Arizona Fall League. At just 19, he has the potential to develop into a cornerstone player, making him an enticing return for parting with a franchise icon like Arenado.
Why This Trade Makes Sense
Arenado’s willingness to waive his no-trade clause for the Phillies, combined with the Cardinals’ need to acquire young talent, makes this deal a logical fit. The Mariners’ involvement ensures that St. Louis receives a high-upside prospect like Emerson—something they might struggle to secure in a direct trade.
The Phillies gain a proven star who could elevate their World Series hopes. The Mariners fill a need at third base while maintaining payroll flexibility, and the Cardinals take a significant step toward their future by landing a top-40 prospect.
Challenges Ahead
While this proposal appears mutually beneficial, executing a three-team trade is always complex. Each team must agree on the value being exchanged, and Arenado’s preferences add another layer of difficulty. However, if all parties align, this trade could redefine the trajectories of the Cardinals, Phillies, and Mariners for years to come.
