failing to timely serve Federal Rule of Civil Procedure 26 disclosures. We affirm.
We have jurisdiction under 28 U.S.C. § 1291. We review orders granting
motions for summary judgment de novo. UMG Recordings, Inc. v. Shelter Cap.
Partners LLC, 718 F.3d 1006, 1014 (9th Cir. 2013). We review orders imposing
sanctions for an abuse of discretion. Conn. Gen. Life Ins. Co. v. New Images of
Beverly Hills, 482 F.3d 1091, 1096 (9th Cir. 2007).
1. Lockhart’s strict liability claims fail because there is no genuine issue
of material fact about the dangerousness of the product. Lockhart brings strict
liability claims based on two theories: design defect and manufacturing defect. To
prove a design defect, a plaintiff must show that the product was in an unreasonably
dangerous condition when it left the defendant’s control. See Golonka v. Gen.
Motors Corp., 65 P.3d 956, 962 (Ariz. Ct. App. 2003). To show a manufacturing
defect, a plaintiff must prove that something went wrong during the manufacturing
process and that, as a result, the product failed to perform as safely as an ordinary
consumer would expect. Id.; Gomulka v. Yavapai Mach. & Auto Parts, Inc., 745
P.2d 986, 988–89 (Ariz. Ct. App. 1987). Lockhart has presented no evidence
relevant to the risks and benefits of the product to prove it was in an unreasonably
dangerous condition. See Gomulka, 745 P.2d at 989 (stating that one way to
determine whether a product is unreasonably dangerous is by conducting a
risk/benefit analysis). She has also presented no evidence that anything went wrong
2
during the manufacturing process. Lockhart’s expert report does not create a genuine
issue of material fact because, although it analyzes the source of the apparent failure
in the leaf blower, it does not present evidence relevant to the risk/benefit analysis
for the product. See Loomis v. Cornish, 836 F.3d 991, 997 (9th Cir. 2016) (“Mere
allegation and speculation do not create a factual dispute for purposes of summary
judgment.” (alteration omitted) (quoting Nelson v. Pima Cmty. Coll., 83 F.3d 1075,
1081–82 (9th Cir. 1996))). Lockhart’s strict liability claims thus fail.
2. Lockhart’s negligence claims fail because there is no genuine issue of
material fact about defendants’ conduct or knowledge at the time the leaf blower
was manufactured. Lockhart alleges negligent design and negligent failure to warn.
To prove negligent design, a plaintiff must show that “the manufacturer acted
unreasonably at the time of design or manufacture in light of the foreseeable risk of
injury from use of the product.” Golonka, 65 P.3d at 962. To prove negligent failure
to warn, a plaintiff must show that the defendant had a duty to warn consumers about
the product’s dangerousness because the product’s risk was known or knowable.
Powers v. Taser Int’l, Inc., 174 P.3d 777, 783 (Ariz. Ct. App. 2007). Nothing in the
record shows what a reasonably prudent manufacturer would have known regarding
the safety of the materials used to make the leaf blower. Lockhart has also presented
no evidence that the alleged inadequacy of any warning caused her injury.
Lockhart’s negligence claims thus fail.

3. The district court did not abuse its discretion by imposing sanctions on
Plaintiff for failing to serve Rule 26 disclosures. Federal Rule of Civil Procedure
26(a)(3) governs pretrial disclosures and requires that each party provide “the name
and, if not previously provided, the address and telephone number of each witness”
as well as “an identification of each document or other exhibit.” Fed. R. Civ. P.
26(a)(3)(A)(i), (iii). Courts have discretion to order sanctions for violations of Rule
26, including by “order[ing] payment of the reasonable expenses, including
attorney’s fees, caused by the failure.” Fed. R. Civ. P. 37(c)(1)(A), (C). Because
Lockhart failed to timely serve Rule 26 disclosures, the district court did not abuse
its discretion by imposing a monetary sanction of a portion of defendants’ attorneys’
fees. Lockhart argues that any failure to disclose was cured by her ultimate
disclosures, which did not include new information. But the district court was
entitled to manage its case schedule, and Lockhart provided no good cause for her
extended failure to disclose even after acknowledging the missed deadline. See
Wong v. Regents of the Univ. of Cal., 410 F.3d 1052, 1062 (9th Cir. 2005)
(addressing failure to disclose witnesses and finding “[d]isruption to the schedule of
the court and other parties . . . is not harmless.”).
AFFIRMED.
