You probably have heard Riley Pint's name by now even if you don't follow the MLB draft; he's the very rare high-school arm who can legitimately reach 100 mph with in-game pitches, and he's one of the subjects of the new book "The Arm" by Jeff Passan, which discusses how gently Pint has been handled by coaches in an attempt to keep him healthy. Pint's arm is indeed special -- he's the hardest-throwing high-school pitcher I've ever personally evaluated -- but he's still more of a thrower than a pitcher, a long-term project for a team with patience and belief in its player development.
Pint pitched at 96-100 mph on Tuesday afternoon in front of a woggle of scouts, including at least 10 scouting directors, several more vice presidents and the Brewers and Rockies GMs. He had a good changeup at 90-91, but no breaking ball to speak of, throwing two bad sliders in the three innings I was behind the plate. He showed poor command and control, walking four and striking out eight in six shutout innings.
Pint's arm is ridiculously fast, even though his stride isn't long and he doesn't have a ton of hip rotation; he's just unusually gifted.
