MEMORANDUM
Jesus Alberto Reyna-Acevedo appeals from the district court’s judgment and challenges the 46-month sentence imposed following his guilty-plea conviction for importation of cocaine, in violation of 21 U.S.C. §§ 952 and 960. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
Reyna-Acevedo contends that the district court violated Federal Rule of Criminal Procedure 32(i)(3)(B) by failing to resolve factual disputes relating to his role in the offense. We review for plain error, see United States v. Christensen, 732 F.3d 1094, 1101 (9th Cir.2013), and find none. Reyna-Acevedo did not file objections to the presentence report, see Fed.R.Crim.P. 32(f), and neither his sentencing memorandum nor his arguments at the hearing sufficiently alerted the district court to the presence of a factual dispute to trigger the court’s obligations under Rule 32(i)(3)(B). See United States v. Petri, 731 F.3d 833, 841 (9th Cir.) (“Only specific factual objections trigger Rule 32(i)(3)(B).” (internal quotations omitted)), cert. denied, — U.S. -, 134 S.Ct. 681, 187 L.Ed.2d 554 (2013).
Reyna-Acevedo also contends that the district court erred by denying him a role adjustment under U.S.S.G. § 3B1.2(b). He argues that the court failed to apply the correct legal standard and that its deficient explanation of its ruling on the issue prevents meaningful appellate review. The record does not support the inference that the district court applied the wrong legal standard. Furthermore, the record is sufficient to permit appellate review and reflects that denial of the adjustment was proper because Reyna-Acevedo failed to carry his burden of proving that he was “substantially less culpable than the average participant” in the criminal scheme. See U.S.S.G. § 3B1.2 cmt. n. 3(A); United States v. Rodriguez-Castro, 641 F.3d 1189, 1193 (9th Cir.2011).
AFFIRMED.
