Defendant's valid waiver of his right to appeal forecloses his claim that the trial court failed to exercise its sentencing discretion ( see People v. Callahan, 80 NY2d 273; People v. Diaz, 304 AD2d 468, lv denied 100 NY2d 561). Were we to conclude otherwise, we would find this claim to be unpreserved and unavailing. Even if we were to conclude that the court mistakenly believed that it had no discretion to impose a lower sentence, there would be no need to remand for resentencing because the court expressed no reservations about the agreed-upon sentence ( id.).
The appeal waiver also forecloses defendant's excessive sentence claim, and if we were to find otherwise, we would perceive no basis for reducing the sentence.
