The Locked On Mariners podcasters proposed a trade of Luis Castillo and $12 million (over two years) to San Francisco for right-handers Hayden Birdsong and Trent Harris.D-train wrote: ↑Fri Nov 21, 2025 9:55 pmSo they are trading Castillo, right? I read some of the replies of Card fans on that site. Some reasonable replies but what do they think JC and Arroyo are in A ball. So easy to look them up if they have the internets...lolharmony wrote: ↑Fri Nov 21, 2025 9:50 pmIt's worth noting that that this year the Washington Nationals finished last in fWAR from the catcher position (but for the Angels, a distant, distant last):

The podcasters proposed replacing Castillo with Washington left-hander MacKenzie Gore, who comes with two years of team control and a projected 2024 salary of $4.7 million.
But think of it as swapping Castillo's guaranteed 2026 salary of $24.15 million for Gore at $10.7 million (his projected $4.7 million salary plus the $6 million the Mariners send with Castillo). Castillo has a guaranteed salary through 2027 while, on top of the $6 million the M's send the Giants in 2027, Gore will be due an arbitration raise in 2027 unless the left-hander is non-tendered.
