According to Mark Zuckerman of CSNWashington.com, the Nationals are calling up Abel de los Santos.
The 22-year-old right-handed reliever has a cool 2.65 ERA, 0.88 WHIP, and 35/7 K/BB ratio in 37 1/3 innings this season with Double-A Harrisburg. And de los Santos was incredibly dominant in 2014 between Low-A and High-A ball. He should be nice addition to the Washington’s middle relief corps.
