Starlin Castro may be a two-time All-Star who has twice hit above .300, but the Cubs would like to see him get "to another level" offensively. Manager Dale Sveum is among those urging Castro to eliminate his leg kick and hand movements, especially in key at-bats like one Friday when he hit a three-run homer. "He's obviously at one level; we want to get him to another whole level," Sveum said. But Castro led the National League in hits last season.
