MLB Ejection & Replay Review Stats: Week 8 Sabermetrics

Ejection & Instant Replay Review Statistics and Sabermetrics are now available for MLB Week 8. As the numbers and trends begin to form, Close Call Sports and the Umpire Ejection Fantasy League continues with the strategic statistics reporting, the first measure of umpire-centric sabermetrics in professional baseball. Visit Instant Replay Review Statistics 101: Week 1 Sabermetrics for an introduction to Ejection & Replay Review definitions and terms, including Review Affirmation Percentage (RAP), also known as QOC (Quality of Correctness), Replay Percentage of Success (RPS), alternatively, 1.000 - RAP = RPS, and Manager's Challenge Success Percentage (CSP). Also included is Team Success Percentage (TSP), which includes all Replay Reviews; both Manager's Challenges and Crew Chief Reviews.
