A game in which a pitcher allows the opposing team no hits.
Also known as a No-No. A baseball game in which the pitcher throws all nine innings and does not allow a single official hit. Can be jinxed if some moron in the audience (whether live, radio or TV) mentions the words "no-hitter".
a game where no batter gets to base by hitting, but may get there because the pitcher walks a batter or accidentally hits the batter with a pitch
