CBSSports.com's Danny Knobler reports that the Nationals have agreed to a contract with veteran lefty reliever J.C. Romero. The contract is a minor-league deal, and as Knobler notes, Romero will open the season down on the farm.
Romero, 36, spent the majority of the 2012 season at the Triple-A level. For his career, he owns an ERA+ of 110 to go with a 1.51 WHIP and 1.40 K/BB ratio. Against Romero, left-handers have managed a lifetime batting line of just .220/.314/.298.
The Nats are set to open the season with only one left-handed reliever -- Zach Duke -- on the active roster, so Romero, assuming he rounds into form, will provide the NL East champs with depth at some point.
"The way I look at it, he gives us insurance," said manager Davey Johnson. "We lost three pretty good lefthanders from last year."
