High 3/4. Quick, whippy, and loose. Some of the best arm action in the minors; can be free and effortless. Similar to Neftali Feliz. Generates plane, and uses his 6'5 frame to his advantage. Front side can get weak, and needs to get front arm up, pointed toward the target. He can put on muscle in his legs, but the flexibility may go away if he adds too much weight overall.
Fastball is free, easy, and loose. Has some arm side wiggle and two seam dart at times. Plenty of life, both up and down in the zone. Command is still an issue, and he often misses high and toward arm side. Loose arm, and should have no problem staying at his current velocity, and may even add a tick.
Change up is out pitch at current. Can generate some swings and misses, and has shown he can throw the pitch in fastball counts. Generates some arm side fade and vertical dropping action, with good arm speed and deception. Command of the pitch isn't quite there yet, but the movement and arm speed give the CH the possibility of playing close to plus. Needs to throw pitch more frequently, and it will be more effective when he has an older catcher guiding.
Has issues inducing spin. Tries to generate torque, but ball comes out flat, and floats. Occasionally flashes a solid average breaker at 11-5, but mostly has trouble throwing it with any conviction. Struggles to throw it for a strike at current, needs a lot of refinement.
Briceno is an extremely intriguing arm, one that has taken strides forward in the last 18 months. He's not adding velocity as once hoped, but his fastball has even more life, and the command is starting to come around. At the highest level, he's going to have to refine the change up and use it as an out pitch, while spinning some strikes with the CB. I've wondered out loud if Briceno should think about developing a splitter, as he possesses massive hands; it may work as an out pitch down the line.
