Diamondbacks Sign First-Rounder Touki Toussaint

MONDAY, 7:18am: Toussaint’s bonus is $2.7MM, well over the pick value of $2.338MM, tweets Nick Piecoro of the Arizona Republic.

FRIDAY, 6:27pm: The Diamondbacks have officially announced a deal with first-round selection Touki Toussaint. Nick Piecoro of the Arizona Republic reported that a deal was close (via Twitter). His bonus is expected to exceed the $2,338,200 slot allocation that came with the 16th overall pick, though precise details remain unknown.

The high school righty, who is still just 17 years old, was rated as high as the eighth-best prospect available entering the draft. MLB.com’s Jonathan Mayo and Jim Callis, who gave him that top-ten billing, say that Toussaint has a quick, loose arm and big curve ball. It sounds as if he still has work to do in commanding his offerings, repeating his delivery, and developing his third pitch (a change), but MLB.com’s experts feel that his raw stuff and athleticism give him an ample chance at success as a professional.

Baseball America (12th) and ESPN.com’s Keith Law (13th) both had Toussaint somewhat lower down their boards, but still agreed that Arizona received a good talent at its place in the draft. Indeed, in the view of Law, Toussaint arguably has more upside than any other high school right-hander in this year’s draft.

Arizona entered the draft with up to $7,228,300 in total pool space. According to Piecoro, via Twitter, the club has now inked all of its first twelve choices. Checking in at MLB.com’s bonus tracker, it appears that the Diamondbacks have saved $430.8K on their post-Toussaint picks, leaving a good deal of room to accommodate the over-slot spending needed to lure him away from Vanderbilt.
