The Nationals signed lefty reliever J.C. Romero to a minor league deal, reports Mark Zuckerman of Nats Insider. The 35-year-old had been released on Friday.
Romero posted a 3.86 ERA, 5.5 K/9, and 6.6 BB/9 with no home runs allowed in 16 1/3 innings for the Phillies this year, missing time with a calf injury.
The Nationals have one lefty reliever on the active roster in Sean Burnett, and he's struggled. Doug Slaten is on the DL for an elbow injury.
