Baseball defence positions

"Baseball is unlike most other competitive sports in that the defense is given control of the ball. Additionally, the number of players on the field at any given time is lopsided in favor of the defense which always has nine players on the field; the offense has between one and four. ...
Each play starts with the ball in the hands of the pitcher, whose job as a member of the defense is to use his skills to somehow prevent the batter from reaching base. The pitcher throws the ball toward the catcher, whose must catch the pitched ball if it is not hit by the batter. In each half-inning, the defense attempts to force three outs.
There are three basic ways in which an out can occur: 1.) If three strikes are recorded against the batter, 2.) if a ball hit by a batter is caught by a defensive player before it hits the ground, or 3.) if a runner who is between bases or has not reached a base to which he is forced is put out by a defensive player in possession of the ball.
If the batter manages to hit the ball, all nine defensive players become active and use the ball in attempting to prevent the batter from reaching base and runners already on base from advancing or scoring. while the offense is busy attempting to move runners around the baseball diamond toward home plate, the defense uses the ball in various ways to achieve outs.
If the defense forces three outs, their team is moved into the offensive role. The exception is if it is the ninth or an extra inning and they are ahead, in which case, the game ends and the defensive team wins." [Defense (sports). Wikipedia]

"Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since 1964. ...
The court dimensions.
A volleyball court is 18 m (59 ft) long and 9 m (29.5 ft) wide, divided into 9 m × 9 m halves by a one-meter (40-inch) wide net. The top of the net is 2.43 m (8 ft 0 in) above the center of the court for men's competition, and 2.24 m (7 ft 4 in) for women's competition, varied for veterans and junior competitions.
The minimum height clearance for indoor volleyball courts is 7 m (23 ft), although a clearance of 8 m (26 ft) is recommended.
A line 3 m (9.84 ft) from and parallel to the net is considered the "attack line". This "3 meter" (or "10-foot") line divides the court into "back row" and "front row" areas (also back court and front court). These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player.
After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball. All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them." [Volleyball. Wikipedia]

"Man-to-man defense is a type of defensive tactic used in team sports such as American football, association football, basketball, and netball, in which each player is assigned to defend and follow the movements of a single player on offense. Often, a player guards his counterpart (e.g. center guarding center), but a player may be assigned to guard a different position. The strategy is not rigid however, and a player might switch assignment if needed, or leave his own assignment for a moment to double team an offensive player. The term is commonly used even in women's basketball, though the gender-neutral 'player-to-player' also has some usage. ...
When defending the ball (i.e. guarding the man with the basketball) away from the basket in basketball, players typically should use a version of the following technique: The defender stands and faces the opponent. He is positioned between the ball and the basket and may be angled in one direction or another depending on the defensive scheme of that defender's team. He has his feet positioned beyond shoulder width with most of the weight distributed to the balls of his feet. However, the defender's heels should not be off the floor as this will put him off balance. The defender's knees should be bent at roughly a ninety degree angle with the bottom of his thighs parallel to the ground. This will place the defenders buttocks in a seated position. The defenders back should be straight with just a slight tilt forward. This will place the defender's head over the center of his body and maintain proper balance. Depending on the teachings of his coach, the defender should position his hands wide as if he were stretching his wingspan or place one hand high and one hand low." [Man-to-man defense. Wikipedia]

"Offensive tactics in set pieces. ...
Throw-ins[edit]
How throw-ins are best handled depends on where it is:
(1) In one's own half the aim of a throw-in may be to retain possession in order to build up the next attack. The throw may or may not go toward the opponents' goal; the most unmarked player may be a full-back who is behind the ball. Such a throw followed by a quickly taken 'switch' pass can be an effective tactic. Under pressure however, the ball is often thrown up the line, toward the opponents' goal line to gain as much ground as possible.
(2) If the thrower is unmarked, a simple tactic is to take a short throw to the feet or chest of a marked player who immediately returns the ball to the thrower.
(3) In the last third of the pitch a player with a long throw can put pressure onto the defenders by throwing the ball deep into the opponents' penalty area, resulting in somewhat similar tactics to a corner kick situation, but with the added advantage of avoiding the offside trap, as an attacking player cannot be offside from a throw in. ...
Goal kicks.
A goal kick is an important 'set piece' that will occur many times in a game and yet few teams practice it. If taken quickly the kick may be taken short to a full-back who has run into a wide position. Although this may gain little ground it retains the all-important possession of the ball. A longer kick to the midfield is more common and it is vital that the midfield unit are in a position to receive it.
Corners.
A corner kick (or "corner") is a real goal scoring opportunity and it is essential to know who is the best at taking a good corner from both the left and right side of the pitch. A good corner will be aimed high across the goal and may be 'bent' towards or away from the goal. At least one of the forwards should be on or close to the goal line when the kick is taken.
Another tactic on a corner is to let the best shooter stay in the back "trash" position and have the defence worried about those up front. The player taking the corner kick makes a small pass back to the trash shooter who has time and space to take a good shot." [Association football tactics and skills. Wikipedia]

"Baseball is played between two teams with nine players in the field on each team. On a baseball field, the game is under authority of several umpires. There are usually four umpires in major league games; up to six (and as few as one) may officiate depending on the league and the importance of the game. There are four bases. Numbered counterclockwise, first, second and third bases are cushions (sometimes informally referred to as bags) shaped as 15 in (38 cm) squares which are raised a short distance above the ground; together with home plate, the fourth "base," they form a square with sides of 90 ft (27.4 m) called the diamond. Home base (usually called home plate) is a pentagonal rubber slab 17 in (43.2 cm) wide. The playing field is divided into three main sections:
(1) The infield, containing the four bases, is for general defensive purposes bounded by the foul lines and within the grass line (see figure).
(2) The outfield is the grassed area beyond the infield grass line between the foul lines, and bounded by a wall or fence.
(3) Foul territory is the entire area outside the foul lines.
The pitcher's mound is located in the center of the infield. It is an 18 ft (5.5 m) diameter mound of dirt no higher than 10 in (25.4 cm). Near the center of the mound is the pitching rubber, a rubber slab positioned 60 ft 6 in (18.4 m) from home plate. The pitcher must have one foot on the rubber at the start of every pitch to a batter, but the pitcher may leave the mound area once the ball is released." [Baseball rules. Wikipedia]
