Nationals placed LHP PJ Poulin on the 15-day injured list, retroactive to July 16, with a left flexor strain.

The 29-year-old southpaw has been a valuable contributor to the Nationals’ bullpen this season, posting a 2.70 ERA, 1.31 WHIP and a 25/21 K/BB ratio across 36 2/3 innings in his 35 appearances. No word yet on how long he’ll be sidelined for.
