UEFL's MLB Umpire Sabermetrics - April 2018

UEFL's MLB Umpire Sabermetrics report for April 2018 features 28 ejections and 253 Replay Reviews through 419 regular season games played.

Though ejections are projected to decrease year-over-year, based on current rates, replays are projected to enjoy a modest increase.*
*The month of April is usually light on ejections. April 2018, for instance, featured seven more ejections than did April 2017.

The attached Most & Least Accurate Umpires, Replay Review contains the top and bottom of the Replay Review table ordinarily found in the "Read More" detailed section of the monthly report.
