The Reds optioned Stephenson to Triple-A Louisville following Thursday's game.
EDGE Analysis
Stephenson tossed five innings and picked up the win in his big league debut Thursday, but he was simply being used as a spot starter, and will head back to Louisville for more seasoning. He is one of the Reds' top pitching prospects, so chances are good he will be back with the big club at some point later this season.
