The Nationals signed right-handed reliever Manny Delcarmen to a minor league contract that includes an invitation to major league, according to his agent Jim Masteralexis. The signing gives the Nationals bullpen depth in the form of an accomplished reliever who last pitched in the majors in 2010.

Delcarmen spent 2013 in Baltimore’s organization, posting a 2.83 ERA in 54 innings for Class AAA Norfolk with 46 strikeouts and 22 walks. Pitching for Licey in the Dominican this winter, Delcarmen has struck out 18 and walked four in 14 1/3 innings, impressing Nationals scouts with a fastball that sat between 93 and 97 miles per hour.

Delcarmen, 31, was once a prized Boston Red Sox prospect and became a crucial piece of their bullpen, peaking in 2007 with a 233 ERA+ over 44 innings for a World Series champion. Between 2005 and 2009, Delcarmen posted a 3.74 ERA over 240 1/3 innings for the Red Sox.

Delcarmen remained in the majors until 2010, when the Red Sox designated him for assignment after a rough stretch. Delcarmen finished the season with the Rockies and has not made it back to the majors, cycling through stints with minor league teams for the Mariners, Rangers, Yankees and Orioles.
