Red Sox spend a lot of money on Cuban teen. A LOT of money...

And apparently, there was good reason for doing so.

Keith Law (ESPN):

If Moncada were in the 2015 MLB draft, he'd be the first or second pick...He'd be a top-10 pick in any draft class, given his potential to play somewhere in the infield and hit for average and power; even if you want to cap his ceiling as that of an average regular at second or third, that's at least a $15 million-a-year player, and the Red Sox would recoup most of their investment before Moncada hits his second year of arbitration.

It may turn out to have been money just thrown away, but it sure looks like they have added a lot of talent to the organization in the last year. And, of course, by signing Moncado, we get the secondary benefit of the Yankees not getting Moncado. So that's a good thing, too...
