New York Mets closer Edwin Diaz served a 10-game suspension earlier this season after he was ejected for "sticky stuff," a rule prohibiting players from using any foreign substance to "discolor or damage the ball," according to rule 3.01 of the official MLB rules and regulations.
Tuesday night, the same umpire, Vic Carapazza, who ejected Diaz addressed Chicago Cubs pitcher Justin Steele for a sticky stuff concern, but instead of ejecting him, asked him to go and wash his hands. He stayed in the game.
