The Nationals have acquired Royals closer Kelvin Herrera, and they didn't have to give up a whole lot to get him. Rookie sensation Juan Soto stays put in Washington, as does fellow outfielder Victor Robles. In return, KC gets three minor leaguers, the most highly rated of whom is Blake Perkins (Nats' no. 8 prospect according to Keith Law). Herrera, who has a 1.05 ERA and 14 saves, joins a Washington pen that already has three guys (Sean Doolittle, Ryan Madson, and Brandon Kintzler) with significant closing experience.
