It's really official now. The Cape Cod Baseball League has officially announced in an April 13th press release that the All-Star Game will be held at Fenway Park. Speculation about Fenway arose on CodBall on December 4th and we announced that it was official on March 7th. Tickets are $10 and general admission. They are on sale beginning April 15th at 10am or noon. The Redsox.com page says noon, the CCBL press release says 10am. I tend to believe Redsox.com, but I'll have my web browser ready at 10am too.
Post your ticket hunting experiences in the comments. But, make sure you're done with your taxes first!
