Re: The "age" of diva umpires
Although great players such as Ruth and Cobb regularly had stormy encounters with umpires, in the last 75 years or so I can recall very, very few great players who did not have cordial relationships with umps. Even someone such as Ted Williams, who certainly had temper tantrums and less than harmonious dealings with the press ("The knights of the keyboard") got on well with umpires.
I can recall Williams in "My Turn At Bat" writing about how he never tried to "show up" an umpire. He recalled one all star game when Jocko Conlan called him out on strikes. Williams wrote that he merely exclaimed "******, Jocko that's no strike" as he returned to the dugout. Nothing else was said until years later when he encountered Conlan at a spring training game (Conlan was a NL umpire). Conlan admitted to Williams that he missed the call and that it had always bothered him.
Another recent thread here discussed the infamous Pete Rose-Dave Pallone dispute, but that incident occurred after Pete's retirement as a player. I cannot recall Rose having any problems with umpires when he was playing.
My guess is that Bryce Harper will learn not to do anything that can set off some of the more sensitive members of the arbiters in blue.
