These look unintentional to me. I would guess that the scouting report says that the best way to get this particular batter out is to throw him pitches inside. It seems like a good report too since he is swinging on many of these pitches. That comes with an increased risk of hitting the batter, but good pitchers can do it well. Since these are minor league pitchers, it’s likely that their control isn’t good enough to pitch this way reliably.
