Yes, it was from back in the day when baseball was thought of as a sport for the poor or those lacking sophistication.
What should Pete have done differently? Should he have stayed on third? Should he have allowed Fosse to have the out because he put them both at risk?
Again, no one that knows the game and looks at that play objectively can fault Pete. There was nothing "bush league" about it. If a fielder blocks the bag then he is the cause of the collision.
Here is an example of poor sportmanship where the runner is going out of his way to cause a collision and in an exhibition game. But because it was not on the big stage, mattered little and has no connection to a legend nobody but Rays fans will remember it. We remember it because when Johnny Gomes took that pussy to the ground it was seen as a team building exercise in our world series season.
