Players of opposing teams shall not fraternize at any time while in uniform. The rule about spectators is there to prevent gamblers from having access to players at the ballpark, and also to protect personnel. But it is broken nearly every day, in fact every MLB team sponsors events that break the rule, such as Autograph Day. The other rule against fraternization is broken before every game in Major League Baseball every season. It s a sign of the player movement that exists in the Free Agent era.
Players often know more people on opposing teams than they do on their own.
When a manager, player, coach or trainer is ejected from a game, he shall leave the field immediately and take no further part in that game . He shall remain in the club house or change to street clothes and either leave the park or take a seat in the grandstand well removed from the vicinity of his team's bench or bullpen. If a manager, coach or player is under suspension he may not be in the dugout or press box during the course of a game. Umpires and opposing teams just wink at this rule, allowing ejected managers to call the shots from the clubhouse tunnel. In many cases the acting manager talks to the ejected manager on the dugout phone, a fact that umpires are fully aware of.
