A double play (also known as twin killing) happens when two outs are made on a single play without an intervening mistake. When a line drive is caught by an infielder who subsequently tags the base before the runner returns, a "unassisted double play" occurs. An out is recorded when the ball is put into play via any means other than a collision with a player at any time during an inning. A run can still score if the batter reaches first base before being retired due to this double play.
This type of double play is very rare because runners will often try to advance beyond second base if they see that there is no possible way for the batter to reach first. This sometimes results in the opposing team scoring despite the fact that you have just used up your only opportunity to retire the batter. However, this does not always happen and depending on how the batter hits the ball, it may be able to be caught safely by one of the fielders.
In addition, an infielder can throw out a baserunner attempting to steal while another player covers the base he was trying to leave. This is called a "pick-off" operation and can also result in an unassisted double play. It is important to note that although these types of plays do occur occasionally, they are very unusual.
The last type of double play involves the use of technology.
A double play (abbreviated DP in baseball statistics) is the act of making two outs on the same continuous play in baseball and softball. Major League Baseball (MLB) defines the double play in the Definitions of Terms and for the official scorer in Rule 9.11. A double play can be made by any player who is positioned at second base or less, so long as that player has the ball. A double play requires two players to be involved in a single action; therefore, it is not considered an error by the umpire.
In addition to the two players involved, a double play requires the involvement of at least one batter during which time he cannot be said to have reached base. A batter does not have to touch home plate to initiate a double play; any part of his body other than his feet can do so. For example, a batter could reach over the plate with his arm while playing backpedal guitar solos to create a double play.
When a double play occurs, each player involved in the action receives credit for an out. If both players make successful throws, then they have recorded a perfect double play. Otherwise, they have recorded an unsuccessful one. The number of successful double plays per team in MLB during 2011 was 1,042/3. In addition, there were three instances of triple plays that year.
When two offensive players are ruled out on the same play, it is called a double play. It's known as "a pitcher's best buddy" since it's twice as beneficial to his cause as any given out. Double plays may be produced in a variety of ways, the most common being on a ground ball with a runner on first. If the ball is not caught, then both runners will advance by one base. A fly ball double play works much the same way except that only one runner is awarded a base when the ball is not caught. A pop-up double play is when the batter hits a ball that is caught but falls for an error while trying to field a third strike. This allows the batter and anyone else at bat to proceed to the next turn without delay while the batter who hit the pop-up can go back to the plate if he or she so desires.
A line drive double play occurs when a player launches a ball down the left-field line for a double. If the fielder making the play does so successfully, no run will score and the batter will have another chance to bat. If the ball is not caught, however, then both runners will advance by one base. A roller-ball double play works similarly except that the ball must travel at least 397 feet (122 meters) before it is considered caught; otherwise, it's a single.
A batting practice double play involves two batters going up to the plate during batting practice.
This is a defensive play in which two players are substituted. When there is a runner on first base and the batter hits a ground ball to the shortstop, this is an example of a double play. The ball is fielded by the shortstop, who tosses it to the second baseman, who steps on second base for a force out, and then throws the ball to first base for a...
It counts as a double play if the defense gets the out at first base and then tags another runner out on the bases. Pitchers with the most double plays often produce a high frequency of ground balls. The most important part of making a good double play is to get the ball to the proper fielder as quickly as possible.
There are three ways that a double play can be executed: 1-2-3, 2-1-2, and 3-3-3.
In a 1-2-3 double play, the first baseman fields a bunt and throws to second base to put out the batter while the second baseman covers first. The third baseman positions himself between the pitcher's mound and home plate and waits for a hit or an error. If the batter strikes out or walks, the catcher steps up and makes the routine throw to first base for the double play. This is how most double plays are made during an ordinary baseball game.
In a 2-1-2 double play, the first baseman fields the bunt and throws to second base who in turn throws to first base for the out. The third baseman stands over first base while the second baseman covers first. If the batter hits a dribbler toward first base, the second baseman may go back and tag the runner there instead of throwing him out at first.
This occurs when the defensive team gets two outs on a single live play. There are several ways for a team to obtain a double play. A batter can strike out or walk off the field of play (or both), or a fielder can catch a ball while another player is covering first base. If this happens, there is no further action taken by the batting team and the other team takes their place at the plate.
The number of times this has happened in any game varies greatly from year to year. In 2008, Major League Baseball played more than 600 games with two outs twice. Pitchers recorded six straight two-out hits once during that season. The most recent time this occurred was on September 29, 2013 during Game 2 of the National League Division Series between the Chicago Cubs and San Francisco Giants. Javier Báez had an infield hit during that game, giving the Cubs two outs with nobody on base.
In 2011, there were four games with two outs twice. One of these occurred on May 23 between the New York Yankees and Boston Red Sox at Fenway Park.
