The St. Louis Cardinals gave a $3.1 million signing bonus to 16-year-old outfielder Wagner Mateo, considered to be among the top amateur free agents from Latin America.
The New York Yankees on Thursday also gave a $3 million bonus to a 16-year-old Dominican prospect, catcher Gary Sanchez.
Cardinals vice president Jeff Luhnow announced details of their signing at a news conference in Santo Domingo.
"We have a tradition of competing and winning and Dominicans have been a big part of that success. We hope that one day soon, Wagner joins Albert Pujols and helps us win," Luhnow said.
