D’Backs Sign Wagner Mateo

The Diamondbacks officially signed 17-year-old prospect Wagner Mateo to a deal worth $512K today. Nick Piecoro of the Arizona Republic reported that the sides were nearing a deal in late April; MLBTR contributor Blake Bentley reported that the deal was done days later and Piecoro added the dollar amount. Today, Piecoro noted (via Twitter) that the deal had become official.

The $512K is a steep, but expected, drop from the $3.1MM deal that Mateo signed with St. Louis last July. That contract was voided by the club out of concerns about Mateo's vision. The Dominican outfielder was rumored to join the Giants in the winter, but a deal never materialized.
