BASEBALL—The National League voted to follow the pattern set by the American, namely, splitting into two divisions next year when its newest franchises—San Diego and Montreal—begin play. The six teams in the National League's East Division will be Chicago, Montreal, New York, Philadelphia, Pittsburgh and St. Louis. In the West Division will be Atlanta, Cincinnati, Houston, Los Angeles, San Diego and San Francisco. Both the National and American Leagues also adopted similar playing schedules, under which each team will play every other club in its division 18 times and each opponent in the other division 12 times. Then, at the conclusion of the 162-game regular season, the first-place team in the East will enter a best-of-five playoff against the winner of the West in its league. The winners of those league playoffs will then meet in the World Series
