Unpublished opinions are not binding precedent in this circuit.

Mario Antwaine Holifield appeals his 188-month sentence imposed following his guilty plea to four controlled substance offenses. Holifield challenges his designation as a career offender under U.S. Sentencing Guidelines Manual § 4B1.1 (2014). The Government seeks to invoke Holi-field’s appellate waiver if we conclude that Holifield’s prior manslaughter convictions remain career offender predicates.

Holifield has two prior convictions for manslaughter, in violation of Alabama law. The Alabama manslaughter statute, Ala. Code § 13A-6-3, corresponds to the generic definition of manslaughter in USSG § 4B1.2 cmt. n.1. United States v. Peterson, 629 F.3d 432, 436-37 (4th Cir. 2011). Holifield’s argument that his prior manslaughter convictions are not predicate crimes is foreclosed by the Supreme *257 Court’s recent holding that the Sentencing Guidelines “are not subject to vagueness challenges under the Due Process Clause.” Beckles v. United States, — U.S. —, 137 S.Ct. 886, 890, 197 L.Ed.2d 145 (2017). Holifield does not dispute that his appellate waiver was knowing and voluntary, and his sentencing challenge falls squarely within the scope of the waiver.

Accordingly, we dismiss the appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
