The designated hitter rule could face its first real test since it was implemented in 1976 after commissioner Bud Selig set up a rule committee. The American League has used the DH for 37 years, but the National League has never considered it. Selig's 14-member committee will consider all on-field issues. The commissioner did not mention the DH rule, but Cardinals manager Tony La Russa and longtime Braves executive John Schuerholz, both listed it as the one thing they potentially would change if they could.
