    UNITED STATES of America, Plaintiff-Appellee, v. Igancio Del ANGEL-BALDERAS, Defendant-Appellant.
    No. 04-50911.
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Decided June 27, 2005.
    Joseph H. Gay, Jr., Assistant U.S. Attorney, U.S. Attorney’s Office, Western District of Texas, San Antonio, TX, for Plaintiff-Appellee.
    Gary B. Weiser, El Paso, TX, for Defendant-Appellant.
    Before WIENER, BENAVIDES, and STEWART, Circuit Judges.
   PER CURIAM:

Ignacio Del Angel-Balderas was charged in a two-coimt indictment with possession with intent to distribute 100 kilograms or more of marijuana and possession with intent to distribute five kilograms or more of cocaine. Del AngelBalderas pled guilty to both counts without the benefit of a plea agreement. He appeals his sentence.

For the first time on appeal, Del Angel-Balderas contends that the enhancement of his sentence based on prior convictions which he did not admit and that were not alleged in the indictment is unconstitutional in light of Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). As Del AngelBalderas did not raise a claim under Blakely or United States v. Booker, — U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005) below, this court’s review is for plain error. See United States v. Mares, 402 F.3d 511, 520 (5th Cir.), petition for cert. filed, No. 04-9517 (U.S. Mar. 31, 2005).

Del Angel-Balderas’ sentence was enhanced based on his prior convictions. Booker reaffirmed the holding in Apprendi that prior convictions are excluded from the facts that must be admitted or proven to the jury. See Booker, 125 S.Ct. at 756. Thus, Del Angel-Balderas’ sentence was not affected by a Booker error or a Sixth Amendment violation. See Booker, 125 S.Ct. at 750, 769. As such, the district court committed no error, plain or otherwise, by enhancing Del Angel-Balderas’ sentence .based on his prior convictions.

Del Angel-Balderas next contends that the district court erroneously denied his request for a minor-role reduction as an abuse of discretion that adversely affected his base offense level and states that, as a mere courier or “mule” in the offense, he was less culpable than the other participants in the drug trafficking scheme.

Del Angel-Balderas was convicted and sentenced based on his possession of the drugs that were found in his tractor trailer. Thus, he is not due a minor-role adjustment. Moreover, his transportation of 322.05 kilograms of marijuana and 89.58 kilograms of cocaine provided an indispensable service to the others involved in the drug-trafficking scheme and was essential to their success. As such, Del Angel-Balderas has not shown that he was substantially less culpable than the average participant. See United States v. Brown, 54 F.3d 234, 241 (5th Cir.1995); Garcia, 242 F.3d 593 at 597. Accordingly, the district court did not clearly err in determining that Del Angel-Balderas was not entitled to a minor-role downward adjustment. See United States v. Villanueva, 408 F.3d 193, 203 n. 9 (5th Cir. 2005).

AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
