General manager Mike Rizzo and director of international scouting Johnny DiPuglia announced the signings of right-hander Ramses Rosario and outfielders Aldrem Corredor, Darryl Florentino and Luis Guzman.
Rosario is a 6-foot-3, 175-pound 16-year-old from Venezuela. According to a club release, Rosario features three quality pitches and has "advanced pitching instincts."
Corredor, also a 16-year-old from Venezuela, bats lefty and can play both corner-outfield positions. Florentino, 16, is 6-foot-2, 180 pounds and regarded as a speedy, high-quality defender with a strong throwing arm.
The Nationals say the 6-foot-1, 183-pound Guzman, a native of the Dominican Republic, should be a prototypical leadoff hitter with some power on offense and potentially plus defense.
