Reds starting pitcher prospect Robert Stephenson will make his debut for Triple-A Louisville on Friday.

The top-100 prospect is one step closer to the majors after going 4-7 with a 3.68 ERA in 14 starts for Double-A Pensacola. He struck out 89 batters and issued 43 walks in 78 1/3 innings.

"Organizationally, we feel Robert is ready for the next challenge," said Jeff Graupe, the Reds director of player development, per the Cincinnati Enquirer.
