Possibly the most ignored rule in baseball?

[TussAgee11]

Anybody see Lastings Milledge for the New York Metropolitans this weekend? Slapping high fives to fans as he ran out to his position in the top of the 11th (maybe 12th?) after hitting his first career homerun to tie the score?

Well, 3.08 (OBR) reads...

"Players in uniform shall not address or mingle with spectators, nor sit in the stands before, during, or after a game. No manager, coach or player shall address any spectator before or during a game. Players of opposing teams shall not fraternize at any time while in uniform."

Well hell, that goes on all the time. How the hell do you police this one, even if you felt like it? And what would the penalty be?

You see it all the time, first baseman talking to the runner, little Johnny going to get a dollar from his Mommy in the stands for a drink. Heck, even an OF tossing the ball into the crowd after the 3rd out of an inning. That could be considered as "addressing".

So what gives about this rule?
