There have been a lot of rumors suggesting the Boston Red Sox could cut ties with veteran third baseman Alex Bregman, but they don't make sense.

The Boston Red Sox could be looking at a very lucrative extension on a new contract for Alex Bregman. Keeping Bregman would mean cuts elsewhere on the roster.

In this MLB mock trade, the Boston Red Sox send star third baseman Alex Bregman to the Seattle Mariners in exchange for ace Luis Castillo and key offensive depth, shaking up the playoff race before the 2025 trade deadline.
