MLB Pipeline began to unveil their Top 10 positional rankings Tuesday night on MLB Network and shortly after on their website. They will go through each position over the next 10 days until they unveil their Top 100 prospects on the 29th.

Today they began their lists with the Top 10 Right Handed Pitching prospects in minor league baseball. While the Cincinnati Reds are flush with pitching prospects, only Robert Stephenson cracked the list of right handers. The soon-to-be 23-year-old cracked the list at #7. Here’s what Jim Callis had to say about Stephenson in the article:

Cincinnati went with an all-rookie rotation in the second half of the 2015 season, and its most promising arm has yet to arrive but is on the verge. Stephenson has knockout stuff — with a mid-90s fastball, a curveball that’s devastating at times and a much-improved changeup — though he doesn’t dominate as much as he should because he’s still figuring out command.

Control seems to be the biggest thing that is holding the righty back at this point. All three of his pitches are above-average, but his walk rate has held him back over the last two seasons as he’s battled to find the strikezone at times. Over that time, he’s gone through long periods where he’s shown good control and an ability to throw strikes, so it’s likely a matter of when, not if, he’s able to really figure things out in the consistency department.

A good example of when he was on top of his control game was from May 23rd through June 19th when he had 11 walks and 51 strikeouts in 37.2 innings pitched. Earlier in the season though, from April 9th through May 13th he walked 22 batters in 28.2 innings. The inconsistency remained throughout the year, going through good and rough stretches when it came to his control.

Here’s some video from the 2015 season of Robert Stephenson that was from July with the Triple-A Louisville Bats.
