Alfonso Soriano hasn't produced as much as the Cubs had hoped when he signed an eight-year, $136 million contract. He was booed when introduced during opening ceremonies at the Cubs Convention. "They don't see me as a baseball player," Soriano said of the fans. "They see me as the contract. They don't see my heart, nothing like that. That's what it is. I know I have a big heart." Soriano's teammates understand his plight and they believe in him. "You give anyone $136 million and unless he's in the top 10 in the MVP every year, he's going to get booed," Marlon Byrd said. "It'll be interesting to see what happens with Albert [Pujols] with the money he got [from the Angels]. [Alex Rodriguez] is one of the best right-handed hitters of all time and he was booed in New York. "Once you get that contract, it happens," Byrd added. "'Sori' is used to the boos and it doesn't bother him. It's all worth it when he gets those cheers, and that's what he loves. When he hits that big home run and goes to the outfield and the entire left field is applauding him and bowing to him, that's what he loves. Boos come with the big market. He played in New York, he knows what that's about." Cubs manager Dale Sveum has heard about Soriano's work ethic. "He's a guy who still put up 28 home runs and drove in almost 90 runs," Sveum said of Soriano, who hit 26 homers and drove in 88 runs in 137 games last season. "You need that kind of bat in the lineup."
