Per Alex Speier:
"Meanwhile, the Sox had already blown past their international spending guidelines (approximately $1.9 million) for the 2014-15 international amateur signing period, something the team did by signing a pair of highly regarded starting pitchers (Anderson Espinoza and Chris Acosta) to a combined $3.3 million in bonuses.
For that reason, the team will not be able to sign any international amateurs under the age of 23 to bonuses in excess of $300,000 in either the 2015-16 or 2016-17 international amateur signing periods. In some ways, then, the Sox seized an opportunity to crash through a closing window on their international amateur free agent possibilities."
