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.

After Triston Casas was ruled out for the rest of the season due to a knee injury, Devers was asked by the Red Sox to take over defensive duties at first base, which is something he's never done for Boston at the MLB level.
