Ben Badler of Baseball America reports that MLB is investigating the age of Cuban defector Aledmys Diaz (who some hope the Pirates will sign as a shortstop of the next few years). Unlike the typical age investigation, here the question is whether Diaz is younger than he claims, because if he's under 23 he's subject to the Latin American signing caps.
But more concerning may be this tidbit at the end:
"Age questions and unblocking issues aside, scouting reports on Diaz's talent remain modest. Though Diaz has played shortstop in Cuba, scouts have said he doesn't have the lateral range, quickness or footwork to stay at the position."
