Atlanta designated Toussaint for assignment Saturday.
Toussaint was once a big-time prospect, and he showed flashes in the big leagues as recently as last season, but the right-hander has struggled to the tune of a 6.26 ERA and 1.63 WHIP in 41.2 innings for Triple-A Gwinnett this season. The Atlanta front office lost patience, but Toussaint is still just 26 years old, so he may be appealing to another team as a reclamation project.
