batsmen usually wear helmets and heavy padding, so that being struck by the ball only rarely results in significant injury—though it is nevertheless often painful, sometimes causing concussion or fractures (although it can also have fatal consequences: Phillip Hughes died after being struck in the head/neck area by a Sean Abbott bouncer during a Sheffield Shield match in 2014). An equivalent to a batter being hit by a pitch in baseball, where the ball hits the batter without bouncing first, would be a beamer in cricket. These are rare and usually caused by the ball slipping out of the top of the bowler's hand. The even rarer intentional beamer provokes strong reaction from batter and crowd alike. The umpire is authorised to take disciplinary action in such instances. The bowler is generally given a first warning, and is dismissed from the game if the offence is repeated. A notable such case was between Waqar Younis and Andrew Symonds: Younis was banned from bowling by umpire David Shepherd for delivering a beamer to Symonds in a match between Pakistan and Australia at the 2003 World Cup; it was the first of only two times it's ever happened during an international match. What height the ball may reach the batter at, and how this plays into the possible deliveries: In cricket, a no-ball is called if the ball reaches the batter above waist-height without first bouncing. In baseball, there is no such limitation, so a pitcher could throw a sinker that is thrown towards above the batter's waist height, with the batter believing and setting up to hit the ball as if it will legally reach him at that height, but then sinks below the waist height upon reaching the batter. There is a major difference in the way in which different bowlers or pitchers contribute to a single game. In baseball, a single pitcher starts the game, and makes every pitch until the manager replaces the tiring pitcher with a relief pitcher. Replaced pitchers cannot return to pitch again in the same game (unless they are shuttled to another position in the field and thus stay in the line-up, a move rarely seen in the major leagues), and a succession of pitchers may come into the game in sequence until it ends. Although moving a pitcher to a fielding position and returning him to pitch later in the game is legal
