Arizona 3, No. 1 Southern California 0 Box Score

TUCSON, Ariz. -- For the first time in 20 years, Arizona (15-5, 5-3 Pac-12) knocked off the No. 1 team in the country.

Freshman setter Penina Snuka was spectacular as she dished out 43 assists to go with 10 digs and two kills for her league-leading 10th double-double of the season. The 43 assists equal the most by any player in the Pac-12 this season in a three-set match.

No. 18 Missouri 3, No. 2 Florida 1 Box Score

COLUMBIA, Mo. -- Missouri earned its first win against a top-five opponent as it upended second-ranked Florida, 3-1 (25-23, 25-23, 23-25, 25-18) on Sunday afternoon in front of a season-high 4,202 fans at the Hearnes Center.

Coming into the match, Mizzou and Florida ranked Nos. 1 and 2 nationally in hitting and Mizzou finished the match hitting .303 while limiting Florida to .237 hitting, its second-lowest of the season. The Tigers are just the fourth team to hit .300 against the Gators this season, joining just Penn State, Stanford and Western Michigan. Senior setter Molly Kreklow was tremendous in the win, spreading 45 assists and setting up open hitters throughout the match. Seven different Tigers finished with kills in the match and five players finished with double-digit point totals.

Junior outside hitter Emily Wilson proved to be an X-factor for the Tiger offense as she led the team with 14 kills on .351 hitting to lead the offensive charge. Freshman Carly Kan was also strong all over the floor on Sunday despite playing against a much bigger Florida front line. But as she has done all season, Kan, a freshman, rose to the occasion and tallied 13 kills on .379 hitting with 12 digs, good for her third double-double of the season and third in four matches. Florida slowed two-time all-American Lisa Henning for the first three sets, but she turned it around in the fourth and tallied seven kills on .500 hitting in the final frame. In fact, Henning and Mizzou hit .471 with 17 kills and one error in the decisive frame. Henning finished the match with 12 kills.

"That's a really talented team that we beat [Sunday]," UW head coach Kelly Sheffield said. "The only way our team is going to be able to win is ...  with really good serves and really good ball control, knowing our assignments and being very tough and hard-nosed defensively. I think we were great in all of those areas. That's why we were able to come up with the win."

No. 6 Washington 3, No. 7 Stanford 2 Box Score

SEATTLE -- A back and forth roller coaster befitting two of the top-10 teams in the country went No. 6 Washington’s way as the Huskies (15-1, 7-1 Pac-12) overcame No. 7 Stanford in five sets. A season-high crowd of 4,914 fans witnessed the Dawgs overcome a rough first set and rally for a 14-25, 25-21, 25-11, 22-25, 15-12 win that moves the Huskies into a tie for first in the Pac-12.

Stanford (13-4, 6-2 Pac-12) outhit the Huskies, .287 to .210, but the Huskies had more kills, 63-61, and a big edge at the service line where UW hit 10 aces while Stanford managed only one. Brittany Howard had 14 kills to lead a balanced Stanford attack, but UW held the Pac-12’s leading hitter, Carly Wopat, to just .133 on offense after she came in hitting .498 for the year.

This was the first top-10 win of the season for the Huskies against their first top-10 opponent. It’s also the first win this season for the Huskies after losing the first set, something they’d only done once before. It’s the second five-setter on the season, as UW also won 3-2 over Gonzaga back in the first week of the season.
