Kerry Wood declined a request to talk with Cubs beat reporters, but told WGN-AM 720 on Wednesday he has an "obligation" to return in '07 and feels "there is something to prove." The Cubs are not planning to exercise Wood's $13.5 million option, and will buy it out for $3 million. But general manager Jim Hendry already has said he would like to have Wood back as a reliever, so all that remains to be decided is what kind of an incentive-laden deal can get it done. "It's obvious Jim and myself have to sit down and discuss that," Wood said. "I know I haven't given this organization or the fans or this team what they paid for two, three years ago. As a player, you feel?you don't want to say 'guilty'?but you [don't] feel like you've done your job and earned your money and gone out and done what you're supposed to do. "There's an obligation there, absolutely. This organization has given me everything I have and gave me a chance to play baseball and they drafted me. There's definitely loyalty here. I love Chicago, I love the fans, I love the stadium, I love Wrigley Field. I love everything about the situation I'm in. "But I understand the reality of the game. Hopefully, it'll be only one conversation. We'll talk and decide what's best for the organization and best for me and, hopefully, that's staying here."
