8. Alex Colome
While this deal came a few years too late for the Nats, Colome is a veteran closer regardless. He may not become the go to closing pitcher for Davey Martinez, but he's similar to Wily Peralta in the sense that he can eat up some later innings for the Nats. Last year certainly wasn't the strongest of Colome's career, but he was pitching in Colorado, home to the most hitter friendly stadium. Colome was another player the Nats signed to a minor league contract, so the trend of singing low risk players continued with him. The bullpen is surprisingly enough one of the stronger components of this Nationals roster, but those areas can never have enough depth, making this move pretty decent.
