Nothing official yet. But there are rumors the Pedro Martinez will throw out the first pitch.
There's also talk that Neil Diamond himself will be here for "Sweet Caroline."
Dr. Dre took one off the wall in BP, too.
UPDATE, 6:24 p.m.: It's Pedro for sure. That'll be cool. Wonder if he will be pitching for one of these teams before the season is over.
Pedro throwing out the first pitch at Fenway and Nomar retiring as a Red Sox. John Henry is settling all family business, but in a good way.
