From what I can gather by a quick internet search, available evidence does not seem to suggest that big-money signings in Latin America have a great payoff for MLB clubs. Here's a list from 2009 of top LA signing bonuses ever: http://www.beyondtheboxscore.com/2009/10/4/1069057/30-largest-latin-american-signing 31 Largest Latin American Signing Bonuses of All Time Tiny by Patrick Clark on Oct 4, 2009 8:39 PM EDT Note that I've excluded Cubans, who have generally played professionally in Cuba before signing with MLB clubs, and who are generally older than the July 2 prospects.

I don't even see anyone whose become a full-time starter here). To be fair, a large number of these have signed in the past coupe of years, so we can't really judge their success, but of that group only J. Montero seems to possess a particularly high probability of success at MLB level. When we look at the top 15 signing bonuses from all international signings, we see much of the same. Except that the clearest example of success comes in the form of Byung-hyun Kim.

I'm not saying otherwise by any stretch. And, frankly, when July 2 rolls around, i find myself wanting to see the cubs mentioned on a big name. But there seem to be few success stories involving the big money deals paid to 16 year-old kids. I like the spread-the-money-around strategy adopted by the Cubs, given the evidence of the success rate of the big bonus deals. I would, however, like to see them more aggressive on deals for players in the 6-figure range, the kinda guys who show more potential than the rather anonymous guys they tend to sign but who also seem to have more questions or ambiguity surrounding them than the big names. And I would also like the Cubs to allocate more money to increasing the number (and possibly quality) of their international scouts, to get more looks at more players (I would also like to increase this for the Cubs' U.S. amateur scouting, a la what the Blue Jays have done).
