The Cubs are looking to trade pitcher Carlos Silva, who says the team misled him about his role this spring. Silva also threw new pitching coach Mark Riggins under the bus for the way Riggins told him he wouldn't make the team. "It's very clear they knew what they were doing," said Silva, who thought it was "weird" last week when the Cubs scheduled him to back up Carlos Zambrano with a three-inning relief outing. "I was like, 'Something's going on. Maybe they know who's going to be the fifth starter.' . . . Don't say people are competing for a spot because it wasn't true. Nobody was competing for a spot. They already [had] their rotation decided. It was very clear." The team's version of events is far different, with more than one member of the organization using the word "delusional" to describe Silva's perspective.
