Does the forfeiture rule apply to a defendant who fails to object to his sentence?

The People contend defendant has forfeited his challenge to his sentence because he failed to object at the sentencing hearing. (People v. Scott (1994) 9 Cal.4th 331, 353 [forfeiture rule applies to "claims involving the trial court's failure to properly make or articulate its discretionary sentencing choices," including the failure "to state any reasons or give a sufficient number of valid reasons"].) We agree that because no objection was raised at the sentencing hearing, the forfeiture rule precludes defendant's claims.
