Cuban right-hander Carlos Sierra agreed to a contract with the Houston Astros, multiple media outlets reported Thursday.
Sierra was considered an international free agent after leaving Cuba legally in February to move to Madrid, as his grandfather is from Spain. He worked out for major league teams in October.
According to MLB.com, the 21-year-old utilizes four pitches, including a fastball that he throws from three angles. He is a three-year veteran of Sancti Spiritus in the Cuban Serie Nacional league, and he participated on the 16-and-under and 18-and-under national teams.
More recently, Sierra pitched for the Tenerife Marlins in Spain's top baseball league, according to Bleacher Report.
The Houston Chronicle reported that the Astros did not make a major financial commitment to Sierra, who is expected to begin his U.S. career in the minor leagues.
