For the first time in nine years, the festive Maryland Million celebration will be conducted at historic Pimlico Racecourse. Focal point of the day is the 11-race card for offspring of Maryland stallions. More than a million dollars in purses are up for grabs for Thoroughbreds of all ages and both sexes. The $200,000 Maryland Million Classic for older horses tops the card. Testing, the defending champion, is one of nine entered to start in the 1 3/16 mile test. Gates open at 10:30 a.m.
