Colorado finished a weekend sweep on Sunday with a thrilling 3-2 win at Arizona. Set scores were 28-30, 25-21, 25-14, 23-25, 15-10.
The Buffs were coming off a 3-0 win over Arizona State on Friday.
The Buffs improved to .500 in Pac-12 play with the win (4-4) and are now 14-5 on the season. The Wildcats fell below .500 overall (8-9) and are now 2-6 in league play.
Colorado outside hitters Frankie Shebby and Alexa Smith hammered 25 kills apiece. The 25 kills were a career-best for Shebby and tied Smith's career-best, which she has done two other times this season. The duo also hit well, with Shebby recording a .357 percentage and five errors on 56 attacks. Smith hit .339 with four errors on 62 swings.
Both also picked up double-doubles as they played well on defense. Smith led the match with 18 digs, while Shebby added a career-high 15 digs. Shebby also posted three blocks in the effort, while Smith had one.
Naghede Abu added 10 kills for the Buffs and tied a team-best with three blocks. Both Anna Pfefferle and Joslyn Hayes each recorded five kills. Pfefferle had a team high hitting percentage at .700 with no errors on seven attacks.
The Buffs hit quite well in the contest at .299, their highest in Pac-12 play this season, thanks in part to Brynna DeLuzio's career-high 57-assist performance. She also added 12 digs and a pair of blocks.
Elizabeth Shelton led UA with 16 kills and Kendra Dahlke tallied 14 kills. Makenna Martin led the match with 21 digs.
Colorado hit .299 with 72 kills and 20 errors on 174 attacks and held Arizona to a .225 hitting efficiency with 65 kills and 25 errors on 178 swings. Both teams served up six aces, but UA had nine service errors to CU's six. The Buffs had the edge in digs (77-69) and blocks (8.5-5.0).
The Buffs return home to Boulder next weekend. They will host USC on Friday and UCLA on Saturday at Coors Events Center.
