share-square-505765 HOUSTON -- Called a “rapid mover to the big leagues,” Cuban outfield prospect Pedro Leon was signed by the Astros on Friday for $4 million (according to a source) -- one of 10 international free agents the club signed. Leon, No. 7 on MLB Pipeline’s Top 30 International Prospects List, has five-tool potential, according to Astros senior scouting advisor Charlie Gonzalez. At the plate, the 22-year-old Leon has a short and compact swing. He doesn't swing and miss much, and he shows power potential to all fields. He's also a plus runner with basestealing potential. On defense, Leon has the tools to stay in center field and displays a strong and accurate arm.
