Say the Red Sox collapse and throw in the towel.
Willson Contreras to Milwaukee for Andrew Vaughn, Jett Williams and one of Jaron DeBerry, Tyson Hardin, Coleman Crow.
Red Sox get Vaughn so they are not left naked at first base DH while Casas rehabs. Jett Williams a Top 100ish prospect who is completely blocked in Milwaukee, and a young pitching prospect, and may be able to get under the luxury tax threshold with more sales.
Contreras would add balance as a right handed power bat could primarily play 1B plus DH against lefties in place of Yelich. Bauers moves into a full-time role in right field bumping Frelick to 4th outfielder.
When Bauers leaves as a free agent this winter the Brewers aren’t left naked at 1B. Contreras under contract through 2027 by which time one of the Brewers first base prospects should be ready to take the baton.
Contreras is owed $30 million approximately from now through the end of 2027 including buy out on option. Vaughn making $7+M this year and likely $10M if retained for 2027, so the net spend for the Brewers is about $13M which is steep and the biggest wrinkle
The next biggest wrinkle would be Contreras’s no trade clause, but I think he’d probably wanna play with his brother despite all the alleged bad blood business with Milwaukee
