In Hall, the Red Sox add a left-hander who can pitch out of the bullpen and strike hitters out. The 26-year-old has just 21 MLB appearances under his belt, but Boston obviously feels like there is some untapped potential here.

The Tigers recently designated Hall for assignment, so they did well to add a future asset in Nunez here. Nunez is a 25-year-old, switch-hitting catcher who has yet to reach Triple-A ball. He will provide depth for Detroit.

There is no fantasy impact here, as neither Hall nor Nunez are going to play major roles with their new MLB clubs in 2020.
