Source: Eddy Julio Martinez agrees with Cubs for $3M signing bonus

Cuban center field prospect Eddy Julio Martinez has agreed to terms with the Chicago Cubs, a source close to Martinez told ESPN's Keith Law.

Martinez will receive a $3 million signing bonus, pending a physical, the source said. He will receive the standard minor league contract, as the current collective bargaining agreement prohibits major league deals for amateur players.

The agreement comes after a potential deal with the San Francisco Giants fell apart earlier this week.

The right-handed hitter is considered to be among the top international prospects. He has been training in the Dominican Republic.

Martinez, 20, a 6-foot-2, 195-pounder, left Cuba last November after playing two seasons for Las Tunas in Cuba's Serie Nacional, according to MLB.com. MLB declared him a free agent in May.
