in baseball, it is a rarely used and potentially risky strategy, as the pitcher may be unprepared to play another position. In cricket, two bowlers begin the game, with those not actively bowling spending time as fielders. Every player in the team, including the wicket-keeper but excluding the 12th man, is available to be used as a bowler. Bowlers alternate bowling overs of six balls each. A bowler will usually bowl for a 'spell' of several (alternate) overs, and will generally bowl the entire spell from the same end of the pitch. A second bowler will bowl the overs missed by the first, from the other end of the pitch, for his own spell, with the two bowlers said to be "bowling in tandem". After a bowler is taken off, he may be, and often is, asked to bowl another spell later in the same innings. The terms "bowling" and "pitching", as words, both denote underarm deliveries, as were once required in both games. The rules for delivery were also initially very similar. Once overhand deliveries were permitted in the respective sports, and pitchers were compelled to toe the pitching rubber instead of throwing from anywhere within the "pitcher's box", the actions of bowling and pitching diverged significantly. Penalties for bad or unfair delivery: The "wide" in cricket and the "ball" in baseball both derive from the concept of a "fair" delivery, i.e., a delivery that the batter or batsman has a fair chance of making contact with his bat. While there is no sharply defined "strike zone" in cricket as there is in baseball (but there are lines known as the return creases perpendicular to the other crease lines which the umpires can use as a guide, and in limited overs cricket specific wide lines are painted on the pitch 17 inches (43.2 cm) inside the return creases), in both cases the umpire must judge whether the ball was delivered fairly. Both the "wide" and the "ball" result in a "penalty". In cricket, like a no-ball, a single run is awarded to the batting team and it does not count as a legal delivery. However, a batsman may still be run out. A no-ball is a delivery in which the bowler or the fielders violate the rules in other ways; it can often occur when the bowler bowls from too close to the batter. It is a delivery in
