The Nationals have announced a trio of roster moves. The club has selected the contract of southpaw Dan Jennings, creating 40-man roster space by designating righty Austin Adams for assignment and clearing an active roster spot by placing third baseman Anthony Rendon on the 10-day injured list with an elbow contusion.

While the Nats had resisted a move on Rendon, their best player, he wasn’t healing quite fast enough from a recent hit-by-pitch and the roster pressure proved too great. His placement is retroactive to April 27, meaning he’ll be eligible to return as soon as May 7.

Jennings, who recently inked a minors deal with the D.C. organization, will try to help steady one of the game’s shakiest middle-relief units. The 32-year-old has long been a steady hurler, with a 2.96 ERA over 344 frames in the past seven seasons.

As for Adams, who’s closing in on his 28th birthday, he has seen minimal opportunities in the majors over the past three seasons. It’s interesting that the club didn’t give him a lengthier audition given the volume of strikeouts he has racked up at Triple-A. After averaging 15.2 K/9 against 3.9 BB/9 in 46 1/3 frames last year with the Nats’ top affiliate, Adams has racked up a 20:3 K/BB ratio in an even ten frames so far in 2019.
