MLB Has Hawk-Eye Everywhere. It Still Cannot Call a Foul Pole. Some Problems Outrun the Cameras.
Major League Baseball has installed Hawk-Eye camera systems across its stadiums for pitch tracking, replay review, pitch-calling devices, an automated ball-strike challenge system, and biometric movement tracking. Yet it cannot reliably determine in real time whether a fly ball passes fair or foul above a foul pole. Orioles players recently raised the question publicly, and it has become a talking point across baseball.
This demonstrates what I would call 'edge-case opacity.' The mechanism: any tracking system is only as good as its sightlines, and the physical geometry of a stadium creates a blind spot directly above the foul pole. The lesson here is that deploying more technology does not eliminate irreducible uncertainty. It merely relocates it. You should always ask where your tools break before assuming they cover everything.
Major League Baseball has integrated Hawk-Eye technology across stadiums for multiple officiating and tracking functions. Orioles players surfaced the fair-or-foul gap during a Wednesday night game.
- Pull up YouTube and search for controversial MLB fair-or-foul home run calls near a foul pole.
- Watch the replay angles available and note which camera positions cannot see the ball crossing the pole height.
- Ask ChatGPT to explain how Hawk-Eye triangulates object position from multiple camera feeds. The gap between what the cameras capture and what the pole obscures is exactly what MLB's engineers are wrestling with.
