In adding Herrera, the Nationals now boast an awesome 1-2 punch in the late innings (with left-hander Sean Doolittle and righty Herrera). The future is now for Washington, so they are less concerned about Herrera's pending free agency at season's end than the Royals were.

Gutierrez could eventually replace Mike Moustakas as the Royals' third baseman. Perkins may take more time but should eventually compete for a spot in the outfield. As for Morel, he is a very raw talent with upside who is several years away from prominence.

Herrera's save opportunities may remain the same going from a bad team (KC) to a good team (Wsh), despite the presence of Doolittle. Herrera's other stats should improve with the Nats. Gutierrez, Perkins and Morel all have keeper-league upside (and value), though it is a bit too early in each case to make any real commitments here.
