Does a defendant have to oppose his sentence on appeal on the same grounds he now asserts on appeal?

^23. At no time in the trial court did defendant object to his sentences on the grounds he now asserts on appeal. To the extent an objection was required to preserve his appellate claims, we have considered his arguments on the merits in light of his contention that his trial counsel was ineffective for failing to object in the trial court. (See People v. DeJesus (1995) 38 Cal.App.4th 1, 27 [court considers constitutionality of sentence to " 'forestall a subsequent claim of ineffectiveness of counsel' "].)
