The captain's acumen in deciding the strategy is crucial to the team's success. The captain makes a number of important decisions, including setting field positions, alternating the bowlers and taking the toss. The captain's job on the team is very important but can be rather stressful at times. Much blame is placed on a captain when his team loses. However, it is considered an honour to be in such a privileged position and much praise is given to the captain when his team wins. The burden of the captain's duties can interfere with his quality of play considerably, slightly, or not at all, depending on how well he deals with the stress of his position.
In the event of a batsman being fit to bat but too injured to run, he may ask the umpire and the fielding captain for a runner. The runner chosen must, if possible, be a player who has already been given out. After a batsman hits the ball, the runner's only task is to run between the wickets in place of the injured batsman.
In all forms of cricket, if a player gets injured or becomes ill during a match, a substitute is allowed to field instead of him; though he cannot bowl, bat, or act as a captain or wicket-keeper. Here the substitute is a temporary role and leaves the field once the injured player is fit to return.
For 9 months from July 2005, the ICC trialed the concept of a Super Sub in one-day international (ODI) cricket and some other limited overs competitions. A single full substitution was allowed, with the replaced player not allowed to return to the game. It was discontinued from March 2006.
