Regarding replay, 498 Replay Reviews averages out to roughly one review for every 1.6 games played. Arguing Replay Review decisions continued to be a non-factor, cementing the finality of Replay Review in baseball. Further supporting this theory, the one Replay Review ejection in 2016 concerned potential bona fide slide interference—a new rule for this season.
As I wrote in last month's Ejections & Replay Sabermetrics analysis, ejections were largely down in April due to a distinct lack of Throwing At and Fighting activity (there were zero fights and one throwing-at ejection in April 2016). Baseball has rectified the issue in May, thanks in large part to this Texas brawl, and Throwing At, Fighting and overall ejections are now back to about-average levels. We are again on pace for a 200+ ejections season.
