WASHINGTON -- The Nationals traded right-hander Emiliano Fruto to the Arizona Diamondbacks on Tuesday for prospect Chris Carter, who then was shipped to the Boston Red Sox to complete last week's deal that sent outfielder Wily Mo Pena to Washington.
Fruto was 3-9 with a 5.26 ERA in 18 appearances, including 16 starts, for Triple-A Columbus in 2007. Washington acquired him last offseason when it traded second baseman Jose Vidro to Seattle.
Carter is a lefty-hitting first baseman who was batting .324 with 18 homers and 84 RBIs at Triple-A Tucson. He becomes the player to be named from Friday's trade in which Washington got Pena and cash from Boston.
In three games with the Nationals, Pena is 5-for-11 (.455) with a double, two homers and three RBIs.
