Adam Dunn – 6’6
He had a long career before he retired, and he spent it with some prominent teams. He played for the Reds, the Diamondbacks, the Nationals, and the White Socks as well as the Athletics. And he had the most unattractive nickname in the game. Due to his height and some other reasons, his fans and teammates called him Big Donkey. Nice, right?
