The new Cubs regime has created a revolving door of hit-and-miss talent this season, but Tuesday it made the first long-term commitment to the future. And the first seven-year, $60 million contract went to a Jim Hendry holdover, Starlin Castro, because "we're building a young core and Starlin's right in the middle of that," according to general manager Jed Hoyer. Castro may not be the last recipient of the new largesse. Hoyer and his boss, President Theo Epstein, might want to get someone like pitcher Jeff Samardzija locked up soon.
