Appellant, a federal prisoner currently serving a 168-month sentence imposed following a plea of guilty to conspiracy to manufacture methamphetamine, in violation of 21 U.S.C. § 846, challenges his sentence on the ground that the district court, in applying the Sentencing Guidelines, erred in denying him a minor role adjustment pursuant to U.S.S.G. § 4B1.1.

Appellant is a career offender. Under the Guidelines, a defendant is a career offender if the following three elements are present (as they are here):

(1) the defendant was at least eighteen years old at the time the defendant committed the instant offense of conviction,

(2) the instant offense of conviction is a felony that is either a crime of violence or a controlled substance offense, and

(3) the defendant has at least two prior felony convictions of either a crime of violence or a controlled substance offense.

U.S.S.G. § 4B1.1. While a career offender's criminal history category is always Category VI, § 4B1.1 indicates that with respect to the defendant's offense level, as distinguished from his criminal history category, "[i]f an adjustment from § 3E1.1 (Acceptance of Responsibility) applies, [a court must] decrease the offense level by the number of levels corresponding to that adjustment." U.S.S.G. § 4B1.1.

In contending that the court should have granted him a minor role adjustment under § 4B1.1, appellant relies on the rule of lenity. The rule of lenity applies if a statute — in this instance, a sentencing guideline — is ambiguous. United States v. Johnson, 155 F.3d 682, 685 (3rd Cir.1998). Because § 4B1.1, by its express terms, only authorizes an adjustment based on acceptance of responsibility, and does not mention the minor role adjustment, and since "the inclusion of one implies the exclusion of others," United States v. Koonce, 991 F.2d 693, 698 (11th Cir.1993), the guideline is not ambiguous and the rule of lenity does not apply. Johnson, 155 F.3d at 685.

Several of our sister circuits appear to hold that the minor role adjustment is not available to a defendant sentenced under the career offender provision. See id. at 684 & n. 4 (citing to the First, Seventh, Eighth, and Ninth Circuits, all of which have held that mitigating role adjustments do not apply in the career offender scenario). Today we make it clear that minor role adjustments are not available to defendants sentenced under § 4B1.1.

Appellant's sentence is, accordingly,

AFFIRMED.
