The Connection Nobody Is Talking About: The Adames Trade
On May 21, 2021, the Rays traded shortstop Willy Adames and reliever Trevor Richards to the Brewers for relievers J.P. Feyereisen and Drew Rasmussen. Rays executive Peter Bendix later called it the most difficult trade he had been part of, and Adames said he spent much of that afternoon crying. The move turned out to define both clubs: Adames became a franchise shortstop in Milwaukee, and Rasmussen became a key arm for Tampa Bay, one of the Rays’ players to watch in this World Series according to Bleacher Report.
Contreras arrived in Milwaukee after the 2022 season and shared the Brewers clubhouse with Adames in 2023 and 2024, until Adames signed a $182 million deal with the Giants. Contreras is now engaged to Adames’ sister, which means the catcher’s future family tree includes the man at the center of a trade that links the two teams in this series.
