MEMORANDUM **

Oregon state prisoner Jose Abel Bar-dales appeals from the district court’s judgment dismissing his 28 U.S.C. § 2254 habeas petition. We have jurisdiction under 28 U.S.C. § 2253, and we affirm.

Bardales contends that the state court’s decision to admit at trial statements he made to a police officer violated his Fifth and Fourteenth Amendment rights under Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966). The state court’s decision was not based on an unreasonable determination of the facts and was neither contrary to, nor an unreasonable application of, clearly established law as determined by the Supreme Court of the United States. See 28 U.S.C. § 2254(d); Oregon v. Mathiason, 429 U.S. 492, 495, 97 S.Ct. 711, 50 L.Ed.2d 714 (1977) (per curiam) (no Miranda warning necessary because defendant was not in custody or otherwise deprived of his freedom of action in any significant way) (internal quotation marks omitted).

Bardales also contends that his sentence violates the Eighth Amendment because it is grossly disproportionate to the severity of his crime. The state court’s determination that the sentence did not violate the Eighth Amendment was neither contrary to, nor an unreasonable application of, clearly established law as determined by the Supreme Court of the United States. See 28 U.S.C. § 2254(d); Lockyer v. Andrade, 538 U.S. 63, 73, 123 S.Ct. 1166, 155 L.Ed.2d 144 (2003) (noting that the only “clearly established law” in Eighth Amendment cases is the gross dispropor-tionality principle, which is applicable only in “exceedingly rare” and “extreme” cases).

AFFIRMED.
