Union add Costa Rican forward Martinez

The Philadelphia Union added a young, promising attacking piece on Wednesday by acquiring 21-year-old Costa Rican forward Josue Martinez from CD Saprissa.

Martinez brings a strong pedigree and attacking flair to the Union, where he joins a strikeforce that boasts other up-and-comers Danny Mwanga and Jack McInerney in addition to stalwart Sebastien Le Toux.
