Chris Carpenter is open to a trade, but he knows one may be unlikely. St. Louis fully intends to contend even without righty Adam Wainwright, who will undergo Tommy John surgery and miss the entire season. With 10 years of service, Carpenter has the right to block any deal. "It's not up to me. If the Cardinals wanted to trade me, obviously I would go. There's no question about that," Carpenter said. "I'm not going hold back or veto or do anything like that if they're looking to move me. "I'm not concerned about, though. I'm concerned about getting myself ready to pitch at the beginning of the season."
