FRIDAY, 2:42pm: ESPN.com's Jorge Arangure reports that the Cardinals will sign Mateo for $3.1MM. GM John Mozeliak solidified the agreement at Mateo's house. The Giants nearly offered him $3.5MM, but backed off at the last minute.
THURSDAY, 7:42pm: According to Baseball America's Ben Badler, the Cardinals are "zeroing in" on 16-year-old outfielder Wagner Mateo, and are prepared to offer him a $3MM signing bonus.
The international signing period begins July 2. If Mateo does indeed land $3MM, it would be the second-highest chunk of money ever tendered to a Latin American amateur. Oakland right-hander Michael Ynoa (or Inoa, depending who you ask) set the all-time record last year when he landed a $4.25MM bonus. The Cardinals began negotiations with Mateo in late May.
