Steven Amamoto send me a link to a press release about the Giants-Mets makeup game:

Baseball Commissioner Allan H. (Bud) Selig issued the following statement today regarding the potential make-up game between the San Francisco Giants and New York Mets on Monday, September 29, 2003.
"While I believe in the sanctity of completing Major League Baseball's entire 162-game championship season schedule using every practical means at our disposal, the Giants have requested that, due to cross country travel and other logistical issues that have arisen, it would be in their best interest to forego playing Monday's game.
