This initiative is especially meaningful to the Orioles, whose director of public relations, Monica Barlow (picture above right), is batting Stage 4 cancer. She joined representatives from each club and MLB for this afternoon's press conference, all of them wearing SU2C T-shirts. It provided the most powerful scene of the Winter Meetings, one that cannot be topped by any trade or free agent signing.
