Wagner Mateo is a 16 year-old center fielder in the Dominican Republic. It's been suggested by Dejan Kovacevic of the Pittsburgh Post-Gazette that the Cardinals are set to offer him a bonus north of $4MM, but Cards vice president/farm director Jeff Luhnow stressed that the team is not ready to make offers (talking to Derrick Goold of the St. Louis Post-Dispatch). The Cardinals did work Mateo out in Florida already. Goold has video and scouting on the kid, as does Kiley McDaniel at Baseball Prospectus. McDaniel suggests the Dodgers and Giants may also be involved.
