Top-10 teams not in tournaments:

No. 2 UCLA

The second-ranked Bruins will conclude their regular season when they matchup with Southern California on Thursday. UCLA, which has not lost a conference game (8-0-2) and last was on the losing end against North Carolina on Sept. 6, has already wrapped up the Pac-12 regular-season crown and a berth in the NCAA tournament.

Bruin goalkeeper Katelyn Rowland has 10 shutouts this year and a goals-against average of 0.32. Darian Jenkins leads the offensive attack with 10 goals, six more than any other UCLA player.

Southern California comes in having won its past two games in overtime. The Women of Troy are 8-9-2 overall and 3-6-1 in the conference, featuring a win at No. 10 Stanford.

No. 8 Santa Clara

Santa Clara has two games remaining on its schedule, as it will play at No. 12 Portland on Thursday night and at Gonzaga on Saturday afternoon. The Broncos are on a nine-game winning streak and have outscored opponents 18-2 in their past three games. They are in first place in the WCC with 21 points and a 7-0-0 conference record, but automatic bid to the NCAA tournament is still up for grabs, as Portland and BYU are tied at three points behind.

Portland beat Saint Mary’s 2-1 last weekend to rebound from a 1-0 loss to BYU, its first loss in 11 games. Gonzaga is eighth in the WCC with a 2-5-0 conference record.

No. 10 Stanford

The Cardinal fell to No. 10 in this week’s poll after a 1-0 loss at Washington State, which snapped a 26-match road winning streak in Pac-12 play. Stanford is 6-4-0 in the conference this year and 13-4-1 overall, which puts it at third place. It will play its last game of the regular season on Wednesday night when it hosts California. The Cardinal are led by Taylor Uhl and Courtney Verloo, who have 10 and nine goals, respectively.

The Bears dropped out of the NSCAA top 25 this week. They had been as high as eighth in mid-October, but then went on a six-game winless streak. They are in eighth place in the conference at 3-4-3 and 10-4-5 overall.
