The Yankees selected Trevor Stephan 92nd overall in the 2017 draft out of the University of Arkansas. The Red Sox drafted Stephan in 2016 but instead chose not to sign and transferred to Arkansas. He led the Razorbacks with an ERA of 2.87 over 16 starts in his 2017 college season and finished with 120 strikeouts in 91 innings.


Fastball – Throws a running fastball that acts more as a two-seamer, it will average out around 93-95 mph but will hit 96-97 mph two to three times a game.

Change-Up – He is still working on his change, but it has become a considerable part of his success this season, sitting 86-87 mph

Slider – His slider works exceptionally well with his running fastball and can be his most dynamic pitch shortly, he can throw a slider/cutter that can range from 82-83 and a more downhill slider that will sit at 77-80 mph


Stephan throws from a very low 3/4 release that can nearly be considered sidearm. This being the main reason he scrapped his curveball early in his professional career as he was not able to get the hard over-spin on it, thus getting the term ‘soft.’ His mechanics are not bad by any means, but they showroom for improvement with men on base. His release point does give some added depth to his fastball, along with the forceful run it has.


Stephan’s fastball will take his to success in the future long enough for him to work on his change-up a bit more. The change-up is already becoming a weapon of his and will most likely top out as an above-average pitch. The slider will be a plus pitch for him once he gets his control down a bit more consistently.

Stephan has some problems with lefties and tends to pitch away from them. While he can still paint the outside zone on them, he tends to pitch around them too often which has led to some issues for him already this season. One being when he misses his mark, he will miss far outside with the slider, or in the middle of the plate and up with the fastball. His attack against righties is far more consistent, and he simply looks more comfortable throwing to them.

Stephan is much farther along than most High-A pitchers. He will most likely end the season in Double-A Trenton, but a trip to Scranton is not far out of possibility towards the end of the season either if the roster game plays to his favor. His future could be in the bullpen, but right now he looks comfortable as a starter, and despite his minor issues, he carries an ERA of 1.85 in six starts for Tampa to this point.
