The Nationals have assigned Orlando "El Duque" Hernandez to Class AA Harrisburg after a successful stint in the Gulf Coast League by the 44-year-old right-hander.
Hernandez, who was signed to a minor-league contract last month, appeared in five games in Viera, allowing one earned run and five hits in six innings of relief work. He struck out nine and did not walk a batter.
The half-brother of Nationals starter Livan Hernandez, "El Duque" has not pitched in the majors since 2007 with the Mets. His signing with the Nats helped facilitate the club's subsequent signing of Cuban right-hander Yunesky Maya, who is currently pitching in the Gulf Coast League.
Don't be surprised if Maya winds up pitching alongside Hernandez in Harrisburg soon. Hernandez also could make his way to Washington as a September call-up if he performs at Class AA.
