Our teammate Keith Law ranks all the farm systems and the Yanks come in ... well, you already the headline. Here is what Law wrote:
I might be jumping the gun here, but I see a lot of star potential on their bottom few affiliates, including new acquisition Jose Campos from Seattle, to go with the two power arms from their Scranton club (Manny Banuelos and Dellin Betances). The flaw in the system is the lack of near-in talent, especially position players, who could either help the big club soon or provide more fodder for trades.
So Law loves him some Jose Campos, who was the "other" player in the Michael Pineda deal. By the way, the Rays were second, while the Jays were third in Law's rankings. The Red Sox were 18th. Go read for yourself. You need Insider credentials.
