Arizona traded 1B Paul Goldschmidt to St. Louis in a blockbuster trade. This was a good trade for Arizona, as Goldschmidt has already shown signs of a coming decline and would command a significant contract next offseason. They’re a rebuilding team and locking up a player in his 30’s doesn’t make sense for them. They also received a good package headlined by potential future ace in Luke Weaver. St. Louis received the best first baseman in the game for a good package, but unless they sign him to an extension, or go far in the playoffs next season, it might end up being a mistake.
