The Gerrit Cole-Clint Frazier trade saga between the Pittsburgh Pirates and New York Yankees is one of the most interesting “what could have been” trade stories of the late 2010s – so much so that it's still being talked about today (by Frazier, anyway).
Reports around December 2017 and January 2018 indicated that the Yankees and Pirates had serious talks about Cole. The proposed framework centered on Frazier, the Yankees’ top outfield prospect and a former first-round pick with elite bat speed and power potential.
The Pirates were intrigued, but the Yankees refused to include Gleyber Torres or Miguel Andújar, whom Pittsburgh reportedly wanted instead.
