In baseball, the double switch is a type of player substitution. The double switch allows a manager to make a pitching substitution and defensive (fielding) substitution while at the same time improving the offensive (batting) lineup of a team. Specifically, the double switch is usually used to avoid a plate appearance (turn to bat) by a newly introduced pitcher (pitchers, especially relievers, are generally poor hitters).

A double switch consists of two substitutions made simultaneously. In the usual scenario: 1) a pitcher replaces a position player who will not be at bat soon, and 2) a position player replaces the former pitcher. The reason for this tactic is that a player must bat in the same spot in the batting lineup as the player he replaces. The advantage is that in the short-term the lineup is strengthened because a poor-hitting pitcher will not soon make a plate appearance. The disadvantage is that a position player (often referred to as the victim of a double switch) must be removed from play and replaced by another, often inferior, position player.

The advantage of the double switch over pinch hitting is that it uses up fewer players. If a relief pitcher is brought in before the at-bat, then the manager could substitute a pinch-hitter for him. However, this would require a new pitcher for the next half-inning. By pulling the double switch, a new pitcher brought in before the at-bat drops far enough in the lineup that he can be left in the game to pitch multiple innings before his spot in the lineup comes up.

Even though a position player was put in the game in place of the pitcher, and a pitcher was put into the game in place of a position player, the position player is not required to pitch, and the pitcher is not required to play the field. In baseball, a new player entering the game can play any defensive position (including pitcher) as long as he bats in the spot in the batting order in which the player he replaced was batting.

While the double switch plays an important role in the National League, the designated hitter (DH) rule in the American League has effectively eliminated the advantages of the double switch and is rarely used. The designated hitter's role is to bat in the pitcher's spot in the lineup. Major League rules do not allow a multiple substitution involving a DH to alter the lineup position of the DH. However, although uncommon, it is possible to forgo the DH privilege, e.g. if the DH becomes a position player, and then utilize the double switch later with that player.

[edit] Example

Consider a double switch made by the Boston Red Sox on October 27, 2007 in Game Three of the World Series against the National League champions Colorado Rockies, played at Coors Field in Denver, Colorado. In the bottom of the seventh inning, Red Sox manager Terry Francona decided to remove relief pitcher Mike Timlin. Instead of a single substitution, though, Francona made a double switch by removing both Timlin and right-fielder J.D. Drew. Replacing Timlin in the batting lineup was Coco Crisp, who took over in center field, and Jacoby Ellsbury was moved to right field, even though this is not part of the switch. Relief pitcher Hideki Okajima was then inserted in the Red Sox batting order for the spot that was occupied by Drew.

As a result, in the top of the eighth inning catcher Jason Varitek led off, followed by short-stop Julio Lugo, then Crisp. This gave the Red Sox an offensive advantage by not having to use a pitcher as the third batter in the inning, especially since pitchers in the American League rarely, if ever, bat during the regular season because of the designated hitter rule. The newly inserted pitcher would not have to bat until the ninth position in Francona's revised lineup. Varitek grounded out when he came to bat and Lugo walked. Crisp, batting third in the inning in place of the pitcher’s hitting position, ended up hitting a single to center field and eventually scored as part of a three-run inning that extended the Red Sox lead in Game Three to 9-5 at the end of 8 1/2 innings. Francona’s use of the double switch rule played a significant role in the 10-5 Red Sox victory and gave the American League champions a commanding three-games-to-none lead in the 2007 World Series.
