Sounds like mlb actually dropped a hammer on the Red Sox over this. http://www.mlbtraderumors.com/2016/07/red-sox-international-penalties.html "The Red Sox have been banned from signing international amateurs that are subject to MLB’s bonus pools for the 2016-17 signing period, reports Yahoo’s Jeff Passan. Furthermore, five prospects that the Sox signed during the 2015-16 signing period have been declared free agents that are free to sign with new teams beginning tomorrow, though each player will retain the initial bonus money he received from Boston. Per Passan’s report, right-hander Cesar Gonzalez, outfielders Albert Guiamaro and Simon Muzziotti, and infielders Antonio Pinero and Eduardo Torrealba. .... Stepping back and looking at this from the perspective of players on the upcoming international market, the punishment from MLB likely voids a fair number of agreements that were already in place between Boston and prospects out of Latin America. Badler recently reported that Venezuelan Roimer Bolivar, whom he had ranked as the No. 31 prospect on this year’s market, was expected to sign with Boston. Beyond that, the Sox were expected to sign shortstops Erik Pena and Raymond Mora as well as catchers Christian Longa and Wilfredo Astudillo. Now, that quintet of players (and presumably several more unreported teenagers) will be on the lookout for new clubs with which to sign. While they’ll undoubtedly find teams interested in paying them, their market may be more limited, as many clubs that aren’t planning to exceed their pool have likely already come close to maxing out their allotted spending limit with advance agreements." Unreported in the article but this might also have a chilling effect on other teams make these kind of package deals going forward.
