It's hard to match him up.
San Diego, for example, has the pitching prospects in Mackenzie Gore and Luis Patino. But they also have 3B locked up with Machado for the forseeable future. And they can't move Machado to SS, where they have Fernando Tatis. And they can't move Devers to 1B, because they have a lot of money tied up in Eric Hosmer at that position.
The Dodgers have youn pitcing prospects, and might need a 3B for next season. But Friedman appears unlikely to move any of them.
The Nats could use Devers at 3B. But they have no pitching prospects worth considering in a deal.
