Conviction and sentence for assault and battery, with finding of prior strike and prior serious felony, is affirmed over claims that: 1) imposition of enhancement was unauthorized where jury made no factual finding that current offense was serious felony; 2) evidence was insufficient that defendant harbored the requisite intent for assault or battery; 3) trial court did not understand it could consider length of the sentence to be imposed when ruling on motion to strike prior strike; 4) counsel rendered ineffective assistance; and 5) imposition of an upper term sentence violated Blakely v. Washington.
