Appeal (cricket)
(重定向自Howzat)

In the sport of cricket, an appeal is the act of a player on the fielding team asking an umpire for a decision regarding whether a batsman is out or not. According to the Laws of Cricket, an umpire may not rule a batsman out unless the fielding side appeals. There have been occasions when a batsman has otherwise technically been out, but the fielding team neglected to appeal so the umpire did not declare him out. An appeal may be made at any point before the bowler starts his run-up for the next ball.
