Baseball Contact Play

The contact play is a base running play in the sport of baseball. It usually refers to a runner on third base breaking for home (but occasionally refers to a runner at second base breaking for third). Similar to the safety-squeeze play, the runner at third breaks for home as soon as he sees that the batted ball is on a downward plane for a ground ball. If there is a runner at second base, he will also break for third if the batted ball is on the first base side of second. The play can backfire if the ball is hit directly at the third baseman or the pitcher as a putout will naturally be made at home plate to prevent the run from scoring. In this situation, the baserunner may freeze and return to third. At this point the runner at third's objective changes from scoring to getting in a rundown in order to provide an opportunity for the batter to end up at second base. The main advantage to breaking for home on contact is that it reduces the amount of time an infielder will have to make a play at home and, thus, increases the likelihood of the runner scoring. A secondary advantage is that the possibility of a contact play will often cause the defensive infielders to "play in," meaning closer to home plate, giving them less time to react to a hit ball and a greater likelihood of not being able to field it cleanly.

The contact play is normally used when there is one out. With no outs, it is generally considered best not to risk being thrown out at home, since there will still be two more opportunities for later batters to drive in the runner. The only exception is when there is also a runner at first, since any ball fielded quickly enough to throw out the runner trying to score is also likely to be an easy double play ball, and the team has a much higher run expectation that inning if the result of the play is an out at home and runners on first and second than if the result is two outs and a runner at third. With two outs, all runners on base automatically break on contact, since there is no point in staying at their base while the fielder gets the final out of the inning by throwing to first base.

Most students of Sabermetrics believe the contact play is proper strategy whenever there is a man on third and one out, since the loss from failure is tiny. Using standard tables of run expectation based on the number of outs and runners on base, the difference between having a runner on third with two outs (the usual result of not using the contact play on a typical ground ball out) and having a runner on second with two outs (the usual result of using the contact play and having the breaking runner caught in a rundown) is only 0.043 runs. When the contact play scores a runner who otherwise would still be at third while an out is recorded at first, the net gain is 0.730. Put another way, even if the contact play failed 16 times for every one time it succeeded, it would improve a team's run scoring overall. Even that understates the advantage, since the need for the defense to play in often results in both the runner scoring and the batter reaching base safely, in which case the net benefit is 1.186 runs, which means that it could fail 27 times as often as it helped and still benefit the team overall.

Baseball

Baseball is a bat-and-ball game played between two teams of nine players each who take turns batting and fielding. The batting team attempts to score runs by hitting a ball that is thrown by the pitcher with a bat swung by the batter, then running counter-clockwise around a series of four bases: first, second, third, and home plate.

Rules and gameplay: A game is played between two teams, each comprising nine players, that take turns playing offense (batting and baserunning) and defense (pitching and fielding).

Baseball field: A baseball field, also called a ball field or a baseball diamond, is the field upon which the game of baseball is played.

Equipment: A rounded, solid wooden or hollow aluminum bat. Wooden bats are traditionally made from ash wood, though maple and bamboo is also sometimes used.

Player rosters: Roster, or squad, sizes differ between different leagues and different levels of organized play. Major League Baseball teams maintain 25-player active rosters.

Non players: In the game of baseball, the official scorer is a person appointed by the league to record the events on the field, and to send the official scoring record of the game back to the league offices.

Distinctive elements: Baseball has certain attributes that set it apart from the other popular team sports in the countries where it has a following, including American and Canadian football, basketball, ice hockey, and soccer.

Defensive Play: Baseball is unlike most other competitive sports in that the defense is given control of the ball.

Offensive Play: Batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher.

Batting order (1-9): The batting order or batting lineup is the sequence in which the members of the offense take their turns in batting against the pitcher.

Strategy and tactics: Many of the pre-game and in-game strategic decisions in baseball revolve around a fundamental fact: in general, right-handed batters tend to be more successful against left-handed pitchers and, to an even greater degree, left-handed batters tend to be more successful against right-handed pitchers.

Baseball Positions

At the beginning of each half-inning, the nine players on the fielding team arrange themselves around the field. One of them, the pitcher, stands on the pitcher's mound.

Defensive Players

Pitcher (P): The pitcher is the player who throws the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk.

Catcher (C): When a batter takes his/her turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher.

First Baseman (1B): First base, or 1B, is the first of four stations on a baseball diamond which must be touched in succession by a baserunner in order to score a run for that player's team.

Second Baseman (2B): The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play.

Third Baseman (3B): The third baseman requires good reflexes in reacting to batted balls, as he or she is often the closest infielder (roughly 90–120 feet) to the batter.

Shortstop (SS): The position is mostly filled by defensive specialists, so shortstops are generally relatively poor batters who bat later in the batting order, with some exceptions.

Left Fielder (LF): Outfielders must cover large distances - speed, instincts, and quickness in reacting to the ball are key. They must be able to catch fly balls above their head and on the run.

Center Fielder (CF): A center fielder, abbreviated CF, is the outfielder in baseball who plays defense in center field – the baseball fielding position between left field and right field.

Right Fielder (RF): Right field is the area of the outfield to the right of a person standing at home plate and facing towards the pitcher's mound.

Offensive Players

Batter: A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, drive runners home, or advance runners along the bases for others to drive home.

Runner: In general, base running is a tactical part of the game with the goal of eventually reaching home to score a run.

Designated Hitter: The rule allows teams to have one player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher.

Pinch Hitter: Batters can be substituted at any time while the ball is dead (not in active play); the manager may use any player who has not yet entered the game as a substitute.

Pinch Runner: The pinch runner may be faster or otherwise more skilled at base-running than the player for whom the pinch runner has been substituted.

Lead Off: A lead or lead off is the short distance that a player stands away from their current base.

Lead Off Hitter: Leadoff hitters must possess certain traits to be successful: they must reach base at a proficient on-base percentage rate and be able to steal bases.

Cleanup Hitter: Cleanup hitters often have the most power on the team and are typically the team's best power hitter; their job is to "clean up the bases", hence the name.
