After watching Jacob DeGrom pitch in the MLB World Series in 2015 for the New York Mets I became intrigued by his poise and control on the mound. For his tall stature DeGrom is very athletic as he was a shortstop in high school.
I noticed DeGrom has a tremendously long stride which has its advantages and disadvantages. By having an extra long stride it normally makes a pitcher land on his hell which can disrupt a delivery and cause imbalance. By doing this it also effects the location of pitches.
Another thing a long stride does is it brings a pitches release point a lot lower in which he doesn’t use his height to his full advantage by throwing downhill.
Another thing I see in his delivery is that he points the ball to center field during his stride towards the plate. This is called pre-probation and it is more difficult to be able to pronate through his release point which could “flatten” out his pitches.
One last negative thing I see is that he slightly picks the ball up to the power position with his elbow and not with his hand. However, he does recover by the time his stride foot lands so this is semi-acceptable.
Now on to the positive attributes of DeGrom. He keeps his elbows below his shoulders for 90% of his delivery. There is a slight window where his throwing arm gets above his shoulder but he recovers. His long stride allows him to release the baseball a lot closer to the plate than the majority of Major League pitchers. What this does it allows the hitter less time to see the pitch and the hitter has to make a quicker decision on the type of pitch and weather to swing or take the pitch. His great hip/shoulder separation is where he generates his 94-97 MPH fastball. He seems to have a strong and flexible core which generates great velocity.
Overall, I do like his delivery despite the few minor flaws that I see. You can see the examples of what I am talking about in the still photos.
