Judgment unanimously affirmed. Memorandum: The court did not abuse its discretion by refusing defendant's request for a different assigned attorney because defendant failed to establish good cause for the substitution (see, People v Sawyer, 57 N.Y.2d 12, 18-19, cert denied 459 U.S. 1178). We further conclude that the court did not abuse its discretion by denying defendant's motion to withdraw his guilty plea. Defendant was advised of his rights, understood the consequences of his plea, and stated that he was satisfied with the advice of his assigned attorney. Defendant admitted that he committed the crime charged, and his belated and conclusory claims of innocence presented the court with an issue of credibility, which it could properly resolve against defendant (see, People v Lynch, 156 A.D.2d 884, 885).
