You can only understand baseball if you've played it at some level...
So says somebody on one of these threads somewhere. I think having played can help your baseball knowledge, but you can pick up an awful lot about the game by watching, listening and reading.
For this thread, please state your highest level of baseball played. No softball or kittenball stats, please.
No school-affiliated ball, but I played summers and my last year was the summer of my age 15 year in the Babe Ruth league. I was a 6'0, 140 pound, R/R 3B/OF. All glove, no hit, with a questionable glove. I played in the All-Star game because the third baseman who was supposed to be there got sick and I was home when they called. I also pitched one game and threw a 2-hitter. We lost 4-2.
As such, I know everything about baseball.
