sentence: Teams can change pitchers during a game.
sentences_after: Teams change their pitchers often because it is hard for a pitcher to throw a full game of nine innings. A pitcher can sometimes throw a no-hitter where no one on the opposite team gets an earned hit. A team can use as many pitchers as it wants to, but it is rare to use more than eight in a game. The ways that a pitcher throws the ball are called 'pitches'. Many professional pitchers use two or more different pitches.
