Shawn Kelley
Shawn Kelley is another arm out of the Nats bullpen that could help the Rockies but he has done very well this year. In 34 appearances, Kelley, 34, has an ERA of 2.59 (167 ERA+) in 34 appearances. His WHIP is also excellent (0.862) and he is walking only 1.4 batters per nine innings compared to 9.2 strikeouts.
The righty is yet another impending free agent on the Nats so he would probably be another rental option for fairly cheap, both on prospects going back and in money, as he is only owed about $2 million for the rest of the season.
Kelvin Herrera
The Nationals acquired Kelvin Herrera from the Royals about six weeks ago to help bolster their bullpen for the rest of the season but if they are selling, they very well might try to trade him away. The 28-year old reliever, combined with the Royals and Nationals, has a 1.83 ERA in 41 games, including 15 saves. He is walking less than two batters per nine innings while striking out just under eight per nine innings.
As we discussed in this article just before he was traded to the Nationals, he is former teammates with Rockies closer Wade Davis and one of their bullpen coaches, before becoming a special assistant for the team, is current Rockies pitching coach Steve Foster.
He is yet another impending free agent so, yet again, we are talking about another rental option.
