  1. MLBAM Stats and Data Capture Symposium on Statistics and Operations Research in Baseball July 11, 2007

  2. MLBAM Stats and Data Capture OPERATIONAL OVERVIEW • On-site data capture (MLB, Triple-A, minor league All-Star Games, Arizona Fall League and Hawaii Winter Baseball, Caribbean Series, World Baseball Classic and other events, etc.) • Call-in system (Double-A, Full-Season and Short-Season A, Mexican Winter League) • Scoresheets (Rookie and complex leagues, Caribbean winter leagues) • Roster and schedule management • Data validation and editing • Historical data sourcing and integration

  3. MLBAM Stats and Data Capture PRODUCTS AND SERVICES • Gameday, wireless and other live data products • Syndication to ESPN and other media partners • Pitch-by-pitch MLB and play-by-play data to all 30 MLB clubs • "Universal stats reports" to MLB PR departments • Minor league "private portal” detailed reports • Ad hoc reports for MLB and minor league clubs

  4. MLBAM Stats and Data Capture CLUB DATA DELIVERY • Files sent daily via FTP in .csv and .txt format • Play-by-play data Pre-game data Complete play-by-play Run and error details Detailed substitutions Ejections Injuries Post-game data • Season-to-date summary data “Card 10” Batting Fielding Pitching Player bio • Box score files Batting Pitching

  6. 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

  7. 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

  8. 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
