MEMORANDUM **

California state prisoner Derrick Lee Billups appeals pro se from the district court’s judgment following a jury trial in his 42 U.S.C. § 1983 action alleging that defendant violated his Eighth Amendment rights. We have jurisdiction under 28 U.S.C. § 1291. We review for an abuse of discretion evidentiary rulings and will reverse only if an erroneous ruling was prejudicial. Allstate Ins. Co. v. Herron, 634 F.3d 1101, 1110 (9th Cir. 2011). We affirm.

Billups’s contention that his trial exhibits were improperly excluded by the district court is unavailing as Billups has not shown that the exclusions “more probably than not” caused his trial to result in a tainted verdict. McEuin v. Crown Equip. Corp., 328 F.3d 1028, 1032 (9th Cir. 2003).

Billups’s contention that the district court did not allow him to subpoena witnesses is unsupported by the record.

AFFIRMED.
