The two sides settled on a signing bonus of $150,000, and DeAza is expected to begin his professional career in the Dominican Summer League. The 6-foot-4 outfielder weighs 190 pounds and is from San Luis, Dominican Republic.
DeAza, who took part in the Dominican Prospect League, became eligible on July 2, 2011, but was passed over by Major League clubs during last year's signing period. He has been working out in Santo Domingo with trainer Josue Herrera, who also has spent time with fellow prospect Luis Castillo of the Arizona Diamondbacks.
According to scouting reports, DeAza currently has the ability to play all three spots in the outfield with an above-average arm and plenty of raw power.
DeAza recently traveled to Florida, where he took part in the Team One Futures East showcase in front of Major League scouts, but it was not immediately known whether that was where he piqued Toronto's interest.
In February, DeAza was selected to the Dominican Prospect League All-Star team. He didn't take part in the DPL's Spring Training this year because of Toronto's interest in his services.
