with an imminent possibility of rain, it is quite common for coaches to update tactics using signals. Hansie Cronje, the former cricket captain of South Africa, once took the field with a wireless link to the coach, Bob Woolmer. Subsequently, the use of gadgets to transmit messages was banned by the International Cricket Council. Regardless, the coach is merely an adviser; it is almost always the case that the cricket captain has complete authority over the team once play starts. In baseball, by contrast, managers and coaches will often direct the players (through hand signals) to carry out a play (such as a stolen base or hit and run), or to field at a particular depth. In fact, "stealing signs" can play an important part in baseball strategy when a player on an opposing team tries to interpret hand signals between pitcher and catcher or between runner and base coach, and possibly then relay this information to another player without being themselves detected. On-field players and captains In cricket, the captain, bowler, and wicketkeeper may all confer over where to place fielders, and what type of ball to bowl. Non-active bowlers may offer advice to the current bowler. The catcher has an outsized role in baseball, having to make many signals to the pitcher on what type of pitch to throw. Sign stealing is an issue. The closest example of a wicketkeeper advising his bowler would be MS Dhoni advising Joginder Sharma in the 2007 ICC World Twenty20 Final in the final over, and this was likely influenced by Dhoni being the captain. Strategy over the course of the game In both sports, strategy varies with the game situation. In baseball, pitcher, batter, and fielders all play far differently in the late innings of a close game (e.g., waiting for walks, trying for stolen bases or the squeeze play to score a decisive run) than they do early, or when one team has already scored many more runs than the other (where batters will be likely to swing at many more pitches and try for extra-base hits and even home runs). The number, speed, and position of baserunners, which have no equivalent in cricket, all dramatically change the strategies used by pitcher and batter. A runner on first base must decide how large a lead to take off the base—the larger the lead, the greater the chance of advancing on
