The Cardinals have signed 16-year-old righthander Ronald Medrano, one of the top Nicaraguan prospects for July 2.

Medrano is 6 feet, 170 pounds and pitches to both sides of the plate with a fastball that sits around the high-80s and has touched 90-91. He has shown good pitchability for his age and feel for his secondary stuff, including a curveball with good spin that could become an above-average offering, as well as a changeup. Medrano trained at the Nicaragua Baseball Academy run by former major league righthander Dennis Martinez and Gary Wendt.

Medrano is the fourth confirmed international signing for St. Louis so far since July 2. The Cardinals also signed Panamanian shortstop Edmundo Sosa as well as catcher Joshua Lopez and outfielder Luis Bandes, who are both from Venezuela.

Last week the Yankees signed lefthander Corby McCoy, who was considered one of Nicaragua's top pitching prospects along with Medrano.
