The Boston Red Sox need to replace Triston Casas at first base, and they could use top prospect Kristian Campbell as the solution.

Spotrac puts his market value at 12 years, $539 million. ESPN's Jeff Passan also recently had Tucker in his rarefied air of players who could sign $500 million contracts. And if the Cubs are the ones making that happen, it's pretty unlikely they'll then turn around and trade for the roughly quarter of a billion dollars left on Devers' deal.

The Boston Red Sox have had a long week and it continued on Monday. Boston got blown out by the Detroit Tigers, 14-2. On top of this, the speculation and rumors about designated hitter Rafael Devers continued.
