MEMORANDUM **

Pedro Morales-Cardenas appeals from the district court’s order denying his motion, under Fed.R.Crim.P. 35(a), to correct the judgment. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

The government contends that the appeal waiver in Morales-Cardenas’ plea agreement precludes our reaching the merits of Morales-Cardenas’ claim on appeal. Because Morales-Cardenas challenges the sentence imposed in the written judgment as unconstitutional, the appeal waiver does not apply, and we may reach the merits. See United States v. Bibler, 495 F.3d 621, 624 (9th Cir. 2007) (citations omitted).

Morales-Cardenas contends that the district court erred when it declined to correct the written judgment to reflect the sentence of nine months imprisonment pronounced at the sentencing hearing. This contention fails because the court’s oral pronouncement of sentence was ambiguous. Although an unambiguous oral pronouncement controls a directly conflicting written judgment, see United States v. Munoz-Dela Rosa, 495 F.2d 253, 256 (9th Cir. 1974) (per curiam), when “the oral pronouncement is ambiguous or open to reasonable interpretation ..., it cannot possibly ‘control.’ ” United States v. O'Brien, 789 F.2d 1344, 1347 (9th Cir. 1986).

AFFIRMED.
