Going into last season the only question mark on a loaded ​Nationals team was the closer. They tried multiple in-house options but nothing seemed to work, so they had to acquire a closer mid-season.​​

To fortify the back end of their pen, the Nationals acquired Sean Doolittle, Ryan Madson and Brandon Kintzler through trades. Doolittle became the closer and the Nationals rolled their way to an easy NL East title with second-best record in the National League.

With Doolittle, Madson and Kintzler all coming back next year, the Nationals could stand pat with their current bullpen. That is not the case, though, as they appear to be in the market for a new closer anyway.

​Greg Holland would be huge addition to the Nationals but he isn't going to come cheap as he had a big year as the closer of the Rockies. Another thing boosting his value on the market is the competition for his services. And with ​former Cub Wade Davis reportedly signing with the Rockies, Holland has got to be the No. 1 target for Washington.

Along with the Nationals, the Cardinals and Cubs have had interest in acquiring the all star closer.

Still, Holland would be worth the expensive cost for the Nats because he might just give them the best bullpen in the National League.
