Toussaint will be one of eight Braves prospects to take part in the Arizona Fall League this year, David O'Brien of The Atlanta Journal-Constitution reports.
A 19-year-old phenom, Ronald Acuna, headlines the group, but Toussiant -- the Braves' No. 9 fantasy prospect -- has taken a big step forward in his own development this season, showing hints of improved control and posting a 10.5 K.9 and 3.6 BB/9 in 105.1 High-A innings before a promotion to Double-A in late July. The young right-hander will need to continue honing his command if he wants to remain on track as a starter, but even if he can't curb the walks he could still eventually make an impact in the majors as a high-leverage reliever.
