Stephenson was recalled from Triple-A Louisville on Friday.
Stephenson has had two of his best starts of the year for Triple-A Louisville over his last two outings but he still allowed three walks in each contest, which remains a big problem for him. It is unclear how the Reds plan to deploy Stephenson in September but even if he gets a shot in the rotation, it's hard to point to a specific reason why he would be worth a look in standard leagues other than the fact that he used to be a top prospect.
