The changes were made at the league's winter meeting Saturday.Pioneer League teams were scheduled to play 70 games last year, with the playoffs being a best-of-five format.

Opening day for next season tentatively is set for June 19.

There will be one more day off next year - the day of the major league All-Star game, plus three travel days. The teams had just two travel days in 1990.
