After further review, the record stands

Bobby Cox's 162 career ejections stand as the most in MLB history, and with replay review taking the argument out of managers' hands, the record is about as safe as they come. John McGraw is second at 121, the most by an active manager is 54 by Cincinnati's Terry Francona, and the Yankees' Aaron Boone is next among active managers with 47. At his current pace of one ejection every 26.3 games, Boone would need another 3,024 games, almost 19 more seasons, to catch Cox.
