Excellent article on the Athletic right now about PCA. Goes into some details about the trade:
“The Mets wanted infielder Javier Báez, a potential free agent. Crow-Armstrong was not the Cubs’ initial target. Early in the negotiations, Hoyer kept asking for Allan, who recently had undergone Tommy John surgery. The Mets, viewing Allan as a future top-of-the-rotation starter, responded that he was untouchable.
Mark Vientos, then a corner infielder and outfielder at Triple A, was another player the Mets and Cubs discussed. Mets acting GM Zack Scott, who worked for the Boston Red Sox from 2004 to 2020, carried his old team’s preferences to his new one. The Red Sox liked Vientos but questioned Crow-Armstrong’s bat. Both, Scott said, had little industry value.
“Only two clubs ever brought his name up,” Scott said about Crow-Armstrong. “Texas asked for him for (Joey) Gallo, who had 1 1/2 years of control, but the New York fit scared me. The Cubs were pushing for a different prospect (Allan) and were mixed on PCA.”
Crow-Armstrong, though, had at least one strong advocate in the Cubs’ organization — assistant GM Jared Banner, who joined the Cubs in December 2020 after serving more than two years as the Mets’ farm director.
The Cubs did not have a player with Crow-Armstrong’s defensive and baserunning skills, making him more appealing than Vientos and others. But as the deadline approached, the teams were at a stalemate.”
