From Bob Klapisch:

Regardless of where the pendulum rests, this will be a sea-change moment in baseball history, particularly in New York. According to one industry official, "several" prominent Yankees will be named by Mitchell in his 2 p.m. news conference in Manhattan. The official, who spoke to a third party who'd seen the final report, predicted, "It's going to be a rough day in the Bronx" after the identities are made public.
