What is the test for overturning a conviction for prosecutorial misconduct?

"A defendant's conviction will not be reversed for prosecutorial misconduct ... unless it is reasonably probable that a result more favorable to the defendant would have been reached without the misconduct." ( People v. Crew (2003) 31 Cal.4th 822, 839, 3 Cal.Rptr.3d 733, 74 P.3d 820 ( Crew ).) To preserve a claim of misconduct for appeal, a defendant must make a timely objection and ask the court to admonish the jury, unless an objection would have been futile and a request for admonition ineffective. ( People v. Hill (1998) 17 Cal.4th 800, 820, 72 Cal.Rptr.2d 656, 952 P.2d 673 ( Hill ).)
