In this direct criminal appeal, Kent Walker challenges the reasonableness of the sentence that the district court 1 imposed upon revoking his supervised release. Having carefully reviewed the record, see United States v. Growden, 663 F.3d 982, 984 (8th Cir. 2011), we conclude that the revocation sentence of 8 months in prison, which was within the advisory Guidelines range and below the statutory maximum, followed by 6 months of supervised release, which was also authorized by statute, was not unreasonable, see 18 U.S.C. § 3583(e)(3), (h); 21 U.S.C. § 841(b)(1)(B); United States v. Petreikis, 551 F.3d 822, 824 (8th Cir. 2009). Accordingly, we affirm the judgment of the district court, and we grant counsel’s motion to withdraw.
