Until Brown develops a third pitch he’ll never be a quality starting pitcher. If you’re a hitter you either sit on a fastball or curve ad wait for him to throw you a hittable pitch. He throws nothing that moves horizontally off the plate so as a hitter it’s easy to lay off pitchers on the corners,
At 6’7, it’s a lot easier to pick up the spin on a breaking pitch too when it starts at eye level due to his height and over the top delivery.
Siitter, cutter, anything. He’ll spend his career in the pen until he develops at least another pitch.
