MLBAM Stats and Data Capture
THE PITCH-F/X SYSTEM

Optical tracking system captures
detailed data describing pitch velocity,
movement and location

Outputs raw data as well as graphical
renderings of pitch trajectory and
strike zone

Permanent installation of two cameras
mounted in weather-tight enclosures

Permanent power and video cabling between cameras and central
computer, consistent with broadcast-quality connections

Central computer mounted in operations area such as scoreboard
control room

MLBAM Stats and Data Capture
HOW DOES IT WORK?

Two cameras at high home and
high first base

Each camera records ~60 images
per second, roughly 30 total
images per pitch

Ball is tracked along entire
trajectory from release point to
termination

Manual operator verifies data and
performs routine maintenance

MLBAM Stats and Data Capture
HOW DOES IT WORK?

Data is transmitted back to a central computer that aggregates and
interprets the data

Software uses images to calculate equations of motion and determine
the ball’s position at any point along the trajectory

Manual operator evaluates data and can reject any invalid or
incomplete data

Accuracy is verified by computing offset between each camera’s
measurement of each point along the trajectory: zero difference
indicates system has accurately centered the pitch

Pitch data also plotted against video to verify accuracy
