Earl Weaver was about 80 years old back in the 1970's. He was the manager of the Orioles and was a beast when he got pissed off. Some of his and Billy Martin's ejections were legendary.
I have a friend who is an umpire. He tells a story about making a close call and the coach came running out and got in his face and said “that was a great call, give me 30 seconds to throw a fit and throw me out”. My umpire friend said to the coach “throw your hat”, and then the coach said “run me” - it was all a show
I enjoyed seeing Lloyd McClenddon playing in Venezuelan winter league in the 80's, he always was a tough competitor, a mad dog in every play and people loved him or hated him.
Lloyd McClendon was one hell of a baseball player, could play ever position except pitcher on the field at a excellent level. Saw him catch a game for the Cubs.
The best managerial ejection I ever saw (in person too) was Earl Weaver vs. the Yankees. An Oriole was called out at second. Earl came charging out for the confrontation. A fan in the stands yelled, “Get back to the dugout, ya fuckin’ runt!” Earl flips his cap around so he can peck at the umpire. He then SITS DOWN on second base. The ump had no choice but to run him. So Earl let’s loose and, eventually, the ump turns and goes to brush off home plate with his back towards second. Earl makes a beeline for him like he was going to kick him in the ass. Instead, the moment the ump was through, Earl kicks dirt all over the dish. Priceless. Even Lou Pinella can’t top that one.
