The Houston Astros can't trade Christian Walker, but it's not for lack of trying. Further hurting his market is the presence of an intriguing, if limited, free agent. The thing is, Goldschmidt will cost a fraction of what Walker will, even with Houston eating part of his contract. Goldschmidt will most certainly settle for a one-year deal, while Walker's contract isn't up until after the 2027 season. There's still a first base market between teams needing a platoon option, and other clubs who could move some pieces around to find room.
