Cubs shortstop Starlin Castro was held out of the starting lineup against Atlanta last night, one night after television cameras caught him not paying attention in the field as a pitch was thrown. As reliever James Russell went into his motion in the sixth inning of Sunday night’s 6-2 loss to the Cardinals, Castro kicked at the dirt and then walked toward the outfield, never looking toward home plate when the pitch was thrown. Cubs manager Mike Quade said yesterday he was “real disappointed’’ and was giving Castro “a mental day off.’’ . . .
