09:45 AM ET 08.12 | Shortstop Starlin Castro has improved by "leaps and bounds," but that doesn't make him immune from sessions with manager Dale Sveum, such as the one the two had Saturday. "It went well," Sveum said. "He was, I don't know if 'remorseful' is the right word, but he knew he made a big mistake [on the basepaths in Friday's 10-8 loss to the Reds]." The mistake came when Castro tried to steal second, lost sight of a single to right field by Josh Vitters and was thrown out at third in the sixth inning Friday against the Cincinnati Reds. The Cubs trailed 8-3 at the time. Sveum was visibly upset after the game but waited until Saturday to talk with Castro.
