I recall that Don Mattingly was forced to remove his pitcher due to two mound meetings in an inning. I've read articles that indicate that a limit was placed on manager-led mound meetings to speed up the game.

The MLB rule reference (8.06):

8.06 A professional league shall adopt the following rule pertaining to the visit of the manager or coach to the pitcher:

(a) This rule limits the number of trips a manager or coach may make to any one pitcher in any one inning;

(b) A second trip to the same pitcher in the same inning will cause this pitcher's automatic removal;

(c) The manager or coach is prohibited from making a second visit to the mound while the same batter is at bat, but

(d) if a pinch-hitter is substituted for this batter, the manager or coach may make a second visit to the mound, but must remove the pitcher. A manager or coach is considered to have concluded his visit to the mound when he leaves the 18-foot circle surrounding the pitcher's rubber.

Are there any historical reasons that caused this rule to be put in place?

    Arguably, in the Don Mattingly case, he was making a second trip while the same batter was at bat, which should have been prohibited by rule (b) to begin with before rule (c) would have come into effect. Commented Feb 24, 2012 at 22:07

The rule is in place so that a manager can't keep coming out and slowing down the game. 1. It annoys everyone 2. He could be intentionally taking his time so that a pitcher in the bullpen can warm up.

  • Point 2 is very plausible, although paying customers probably would prefer point 1!

This was at least in place when I was a child and first watching baseball games in the mid 1980's. This person says early 1970's. This edition of Baseball Digest from 1986 had the rule listed at the bottom of a page, but I'm not sure if that's to simply convey the rule or to identify rule changes that enacted in the year.


I don't believe previous editions of the official MLB rules are publicly available, so I was not able to check when this particular rule was first enacted. All I can prove is that it existed as of 2006.

My guess is that this particular rule was added to speed up the pace of the game.
