Designated Hitter - Background and History

Background and History

The rationale for the designated hitter rule is that, with a few exceptions — most notably Babe Ruth, who began his career as a pitcher with the Boston Red Sox — pitchers are usually weak hitters who ordinarily perform once every four or five games. The designated hitter idea was raised by Philadelphia Athletics manager Connie Mack in 1906, though he was not the first to propose it. The rumors were that he grew weary of watching Eddie Plank and Charles Bender flail at pitches when at bat. Mack's proposal received little support and was even lambasted by the press as "wrong theoretically". The notion did not die. In the late 1920s, National League president John Heydler made a number of attempts to introduce a 10th man designated hitter as a way to speed up the game, and almost convinced National League clubs to agree to try it during spring training in 1929. However, momentum to implement the DH did not pick up until the pitching dominance of the late 1960s. In 1968, Denny McLain won 31 games and Bob Gibson had a 1.12 ERA, while Carl Yastrzemski led the American League in hitting with a .301 average. After the season, the rules were changed to lower the mound from 15 to 10 inches and change the upper limit of the strike zone from the top of a batter's shoulders to his armpits. In addition, in 1969 spring training, both the American League and National League agreed to try the designated pinch hitter (DPH), but they did not agree on the implementation. Most NL teams chose not to participate. On March 6, 1969, two games utilized the new DPH rule for the very first time. Two newly formed expansion teams, the Montreal Expos and the Kansas City Royals would participate in one such game, and the New York Yankees and Washington Senators in the other. On March 26, 1969, Major League Baseball nixed the idea for the time being. Like other experimental baseball rule changes of the 1960s and '70s, the DH was embraced by Oakland A's owner Charlie O. Finley. On January 11, 1973, Finley and the other American League owners voted 8–4 to approve the designated hitter for a three-year trial run.

On April 6, 1973, Ron Blomberg of the New York Yankees became the first designated hitter in Major League Baseball history, facing Boston Red Sox right-handed pitcher Luis Tiant in his first plate appearance. "Boomer" Blomberg was walked.

As would be expected, the result of the first season of the DH was that the American League posted a higher batting average than the National League, something which has remained consistent to this day.

The designated hitter offers American League managers two options in setting their teams' lineups: they can either rotate the role among players (for example, using a left-handed hitting DH against a right-handed pitcher and vice-versa) or they can employ a full-time designated hitter. It also allows them to give a player a partial day off. The adoption of the designated hitter rule has virtually eliminated the use of the double switch in the American League.

In recent years, full-time DHs have become less common, and the position has been used to give players a partial off-day, allowing them to bat but rest while the other team is batting. Only a handful of players compile over 400 at-bats as a DH each year.

With the Houston Astros moving to the American League for the 2013 MLB season, which will require Interleague play season-round (as well as the Astros to start using a DH full-time), there is debate within MLB to unify the rules of the two leagues, with either the National League adopting the DH or the American League returning to its pre-1973 rules and have the pitcher hit, like the National League.
