The Nationals added veteran reliever David Carpenter on Thursday in a deal with the Yankees. Washington acquired the 29-year-old right-hander in exchange for Minor League infielder Tony Renda, and the Nats moved Nate McLouth to the 60-day disabled list in order to make room for Carpenter.
Carpenter has pitched in the big leagues in each of the past five seasons, and he's logged an 11-11 record and a 3.73 ERA in 210 appearances in the Major Leagues. Carpenter, a West Virginia native, was 0-1 with a 4.82 ERA in 22 appearances with the Yanks this season.
