10/3/2012-The Pecos League will remove the the DH in the 2013 season. The Pecos League did not have a DH in the first half of the 2011 season. The DH was inserted in the halfway point of the 2011 and the entire 2012 season. The removal of the DH allows for pitchers to hit and lower scoring games in high altitudes.

In baseball, the designated hitter rule is the common name for Major League Baseball Rule 6.10,[1] an official position adopted by the American League in 1973 that allows teams to designate a player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher each time he would otherwise come to home plate, rather than letting the pitcher bat. Since then, most collegiate, amateur, and professional leagues have adopted the rule or some variant; MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.
