This article by Baseball America discusses the ways that some MLB teams may try to evade the bonus pool limits on signing international free agent. Teams will be limited to annual total bonus amount of $2.9 million for international signings after July 7. Most of the efforts at evading the new CBA rules are best described as "cheating." Some might be described as finding "loopholes." I wouldn't want the Astros to cheat, but cheating by other clubs will have a negative effect on the honest teams' ability to sign the international players that they target. The Rangers already have made some signings that might be interpreted as looking for a loophole.
A couple of the exceptions to the rules are legal and may place a premium on certain players who meet those exceptions. For instance, a prospect who is cut by another team is eligible to be re-signed with another team for a bonus that will not count against the bonus pool. MLB says they will not interpret this exception as applying to players whose contracts were cancelled by MLB due to drug suspensions or age discrepancies. Mexican born prospects who play for a Mexican League team will not have the full bonus count toward the bonus pool, because typically 75% of the bonus is channeled to the Mexican League team. (I recall that, shortly after he took the GM job, Luhnow said that he wanted the Astros to become more active in the Mexico prospect market.)
Some of the mentioned evasions are very shady, and reminds me of economists' observations that attempting to prevent markets from clearing supply and demand will create unintended consequences. This can take the effect of non-monetary compensation, like giving the prospect or his family a new luxury automobile (reminds me of college recruiter cheating) or channeling money or perks to friends and family. of the prospect. Another form of cheating is bribing the agent or "trainer" for the 16 year old since that individual may control the prospect's signing decision.
Anyway, the article raises some interesting questions....and also raises the question as to how much effort MLB will put into enforcement against teams cheating.
