Carlos Pena has signed a deal with the Cubs, but he won't forget all the support he received from fans in Tampa Bay. He took out a half-page ad in Monday's St. Petersburg Times in which he poured out his heart to express his feelings. "Now I know more than ever that anything is possible if I believe it to be with all my might. When I first became a Ray we were the worst team in baseball. But what was about to happen next, not even the greatest fiction writer in the world would have been able to come up with it. "I have never in my life seen a team come together in such a way, where everyone humbly but undeniably believed with all their strength that we could make it to the top. This is the story of the little engine that could. The underdog story. The story of a team in oblivion, that went on to become American League East Champs twice, American League Champs once, and made a World Series appearance. "I am so honored to be able to say that I was a part of that. I am so honored to be able to say that I was a RAY. Thanks for cheering for me when I performed well, but most importantly thanks for patting me on the back and encouraging me when it was difficult."
