Third-ranked Arizona lost 8-0 Friday to No. 12 UCLA at Easton Stadium in Westwood.
The game ended on a three-run homer by the Bruins Bubba Nickles. UCLA starter Rachel Garcia threw a two-hit shutout.
Two Wildcat errors led to five unearned runs for the Bruins.
Arizona (47-6, 17-5) still controls their own fate in the conference though, as Utah lost 5-0 to Oregon State. UA's magic number is two.
The Bruins (38-12, 12-7) are currently tied with Washington for fifth place in conference play.
