The
 Red Sox dove in big time. The Sox went over their international 
spending limit (which means a penalty and restrictions on signings next 
year) by signing Cuban infielder Yoan Moncada to a  
$30 million contract.  
Boston can't sign an international player to a bonus of more than 
$300,000 until July 2 of 2017, but they have Moncada, who is considered 
talented enough that he would be the first pick in the 2015 MLB Draft 
were he eligible, since is considdered as a Top 15 prospect by baseball 
scribes.
The
 current trend is clearly to seek out South-of-the-Border talent in 
Cuba, the Caribbean and Latin America. With additional interest in these
 youth baseball areas, the cost of signing prospects is going up (which 
is why MLB put in signing restrictions).
