OAKLAND, Calif. (AP) — Baseball’s new expanded replay rules this season might mean most managers start minding their manners.

That seems to be the case so far, with managers calmly leaving the top dugout step to chat with an umpire to either challenge a play or request that the umpire take a second look via review.

Through Wednesday’s games, in a count by baseball and STATS, there were 64 replays with 21 of those overturned. Nineteen of 48 were on manager challenges, and two were among 16 umpire-initiated reviews.

There could be a missing element for the baseball purists so accustomed to those screaming matches between manager and umpire made famous by by the late Hall of Famer Earl Weaver, retired Braves skipper Bobby Cox or cap-kicking Lou Piniella.
