In the biggest surprise of the offseason, Johnny Damon agreed to a four-year deal with the rival Yankees on Tuesday. His parting message to fans: ''My message to Sox fans is I tried. 'I tried everything in my power. Unfortunately I know they are going to be upset. I'm always going to remember the good times, the World Series, the three out of four years we made the playoffs. I want them to know I appreciate them and I tried."
