NEW YORK CITY — Greetings from Yankee Stadium. The live blog starts when the HBO doubleheader kicks off, so come to this blog entry around then. I only ask two things: 1. I’ll post round-by-round, and will try to respond to comment in between. So if you’re expecting more than that, I can’t help you, which means complaining will get you nowhere. 2. Don’t keep asking when such and such fight starts, because they don’t start at a set time. Wait no more than three minutes and you’ll get the information you need about what round each fight is in at the moment.
