Volatile velocity, low as 86; downhill plane from long arms and extension, hard arm-side run at its best; inconsistent command
Inconsistent, flashes average; nice sweeping action, tight at its best, spun well at times; struggled to keep shape, several backed up; needs reps but can get there
Not a standout pitch; mild arm-side fade, used sparingly; inconsistent, meshed in with fastball, just looked like a slower version
Perdomo benefits from his tall body and extension, utilizing it well to create downward plane with his running fastball. With average velocity, it's a nice pitch, but command issues are very apparent with all of his pitches. The slider was inconsistent through the entire outing, showing different shapes but flashing the makings of an average pitch with greater consistency. The changeup needs a lot of work, as he only threw a handful that had the look of a slower version of his fastball.
Long-term outlook is a bullpen arm, with some potential be a swingman if he makes strides with his change. The velocity and movement on his fastball combined with the potential average slider makes it more likely he settles into a middle-relief role.
