Name: Dietrich Enns
DOB: May 16, 1991
Repertoire. Fastball, Changeup, Slider, Curveball.
Fastball. While he doesn't hit the high-90s with his fastball it often times plays at an above average to plus level with his combination of solid command, deception, and late life explosion. He sat mostly in the 90-92 mph range as a starting pitcher upon his return from Tommy John surgery in 2015 and that's the range he sat mostly in as a starter even before his surgery. However, while it's certainly within the realm of possibility that he could add a tick or two on to his fastball the further he gets away from his surgery, the fact is he has sat at a higher level in shorter relief stints in the past, more in the 91-94 range as a reliever. On paper he boasts an above average fastball velocity-wise for a left-hander but it can [and often times does] play higher.
Other Pitches. Between his slider and changeup Enns has two very good big league secondary pitches in his arsenal, the most effective of which has become his above average slider. He entered the professional ranks with a big league average changeup as his main go-to secondary pitch and it still serves as his primary contact out-pitch these days too, but his slider, once a loopier high-70s breaking ball, has become a firmer 80-84 mph power slider over the years that can be a very consistent strikeout pitch. The progress of his slider is a big reason why he's been able to strike out better than a batter per inning pitched thus far in his career. He and the Yankees introduced a curveball into his repertoire full-time last season after tinkering with it behind the scenes even before his surgery and it's slowly developing into a reliable early-count strike pitch for him. It hasn't yet become a huge strikeout asset for him but, like the slider, it shows some long-term above average potential.
Pitching: Flip-flopping roles between starting and relieving during his career, Enns has had the ability to change his approach accordingly. As a starter he throws a lot of early strikes looking to induce quick contact and keep his pitch counts low but as a reliever he looks for the strikeout early and often, and he's been able to do that rather effectively now that his slider has been completely revamped. Showing a bulldog mentality in either role, he is one of the better strike-throwers around too, especially for a left-hander, and does not beat himself by walking too many batters. He is very athletic and that not only helps him repeat his delivery well but field his position well too.
Projection. One of Enns' best assets, his versatility on the mound, is what also muddies his long-term projectable role too. He has the kind of solid three-pitch [perhaps even four pitches should the curveball continue to progress] big league arsenal, solid mechanics, and natural strike-throwing ability to potentially become a middle to [more likely] back-end big league starting pitcher someday, but with his fastball playing a level higher in shorter relief stints and with the slider now becoming a wipeout pitch against left-handers [lefties are hitting a pathetic .150 against him with just one home run allowed over the past three seasons] there is also a real temptation to move him into the bullpen full-time. He's going to be Rule 5 Draft eligible in 2016 and left-handers with his kind of complete arsenal are a rare commodity so the ticking clock might force his role more on to the bullpen side of things in the immediate future. He projects best effectiveness-wise as a reliever short-term, one who could slide in rather easily as a middle reliever and potential setup man in a sort of Justin Wilson type role, with the caveat that he could still blossom down the road as a late-blooming starting option too, especially if the Yankees, currently loaded with left-handed relief options, decide to stick with him in the rotation short-term regardless of his impending Rule 5 status. He gives the Yankees some real options.
ETA. 2017. Prior to his Tommy John surgery Enns was well on his way towards a potential 2016 big league arrival time. While it isn't impossible for him to still fulfill that kind of ETA, a lot would have fall into place for that to happen. For now he seems destined for Double-A Trenton to start the season and another solid season would have him big league ready the following year at minimum.
