The number of games between interleague rivals such as the Yankees and Mets, Cubs and White Sox
, and Dodgers and Angels will be reduced under Major League Baseball's new schedule format for 2013.
Players' union head Michael Weiner said Tuesday that in most instances the rivalry games will be cut from six to either four or three. The new format was caused by next year's move of the Houston Astros
to the American League, creating two 15-team circuits and the need for interleague play throughout the season.
"It wasn't fair to have six games against an opponent that other teams in your division didn't," Weiner said Tuesday during a question-and-answer session with the Baseball Writers' Association of America. "The Mets, for example, would say `Why do we have to play the Yankees six times every single year when some of our division opponents are playing teams that aren't traditionally as strong? We understand we've got to play the Yankees every year. That's OK. Why should we play six?"'
Teams in a division will play three games each against teams in another division: for example, the NL East vs. the AL Central. The interleague rivalries will be either one three-game series or a home-and-home of two games each, Weiner said.
